+Adds options to the :prop_dir:`COMPILE_OPTIONS` directory property.

-exist to add preprocessor definitions (:command:`target_compile_definitions`
-and :command:`add_definitions`) or include directories
-(:command:`target_include_directories` and :command:`include_directories`).
+Arguments
+^^^^^^^^^
 
 Arguments to ``add_compile_options`` may use "generator expressions" with
 the syntax ``$<...>``.  See the :manual:`cmake-generator-expressions(7)`
 manual for available expressions.  See the :manual:`cmake-buildsystem(7)`
 manual for more on defining buildsystem properties.
+
+.. include:: OPTIONS_SHELL.txt
+
+Example
+^^^^^^^
+
+Since different compilers support different options, a typical use of
+this command is in a compiler-specific conditional clause:
+
+.. code-block:: cmake
+
+  if (MSVC)
+      # warning level 4 and all warnings as errors
+      add_compile_options(/W4 /WX)
+  else()
+      # lots of warnings and all warnings as errors
+      add_compile_options(-Wall -Wextra -pedantic -Werror)
+  endif()
+
+See Also
+^^^^^^^^
+
+This command can be used to add any options. However, for
+adding preprocessor definitions and include directories it is recommended
+to use the more specific commands :command:`add_compile_definitions`
+and :command:`include_directories`.
+
+The command :command:`target_compile_options` adds target-specific options.

+^^^^^^^
+
+.. _WRITE:
+.. _APPEND:
+
+.. code-block:: cmake
+
+  file(WRITE <filename> <content>...)
+  file(APPEND <filename> <content>...)
+
+Write ``<content>`` into a file called ``<filename>``.  If the file does
+not exist, it will be created.  If the file already exists, ``WRITE``
+mode will overwrite it and ``APPEND`` mode will append to the end.
+Any directories in the path specified by ``<filename>`` that do not
+exist will be created.
+
+If the file is a build input, use the :command:`configure_file` command
+to update the file only when its content changes.
+
+.. _TOUCH:
+.. _TOUCH_NOCREATE:
+
+.. code-block:: cmake
+
+  file(TOUCH [<files>...])
+  file(TOUCH_NOCREATE [<files>...])
+
+Create a file with no content if it does not yet exist. If the file already
+exists, its access and/or modification will be updated to the time when the
+function call is executed.
+
+Use TOUCH_NOCREATE to touch a file if it exists but not create it. If a file
+does not exist it will be silently ignored.
+
+With TOUCH and TOUCH_NOCREATE the contents of an existing file will not be
+modified.
+
+.. _GENERATE:
+
+.. code-block:: cmake
+
+  file(GENERATE OUTPUT output-file
+       <INPUT input-file|CONTENT content>
+       [CONDITION expression])
+
+Generate an output file for each build configuration supported by the current
+:manual:`CMake Generator <cmake-generators(7)>`.  Evaluate
+:manual:`generator expressions <cmake-generator-expressions(7)>`
+from the input content to produce the output content.  The options are:
+
+``CONDITION <condition>``
+  Generate the output file for a particular configuration only if
+  the condition is true.  The condition must be either ``0`` or ``1``
+  after evaluating generator expressions.
+
+``CONTENT <content>``
+  Use the content given explicitly as input.
 
-::
+``INPUT <input-file>``
+  Use the content from a given file as input.
+  A relative path is treated with respect to the value of
+  :variable:`CMAKE_CURRENT_SOURCE_DIR`.  See policy :policy:`CMP0070`.
+
+``OUTPUT <output-file>``
+  Specify the output file name to generate.  Use generator expressions
+  such as ``$<CONFIG>`` to specify a configuration-specific output file
+  name.  Multiple configurations may generate the same output file only
+  if the generated content is identical.  Otherwise, the ``<output-file>``
+  must evaluate to an unique name for each configuration.
+  A relative path (after evaluating generator expressions) is treated
+  with respect to the value of :variable:`CMAKE_CURRENT_BINARY_DIR`.
+  See policy :policy:`CMP0070`.
+
+Exactly one ``CONTENT`` or ``INPUT`` option must be given.  A specific
+``OUTPUT`` file may be named by at most one invocation of ``file(GENERATE)``.
+Generated files are modified and their timestamp updated on subsequent cmake
+runs only if their content is changed.
+
+Note also that ``file(GENERATE)`` does not create the output file until the
+generation phase. The output file will not yet have been written when the
+``file(GENERATE)`` command returns, it is written only after processing all
+of a project's ``CMakeLists.txt`` files.

+        [EXCLUDE] [PERMISSIONS <permissions>...]] [...])
+
+The ``COPY`` signature copies files, directories, and symlinks to a
+destination folder.  Relative input paths are evaluated with respect
+to the current source directory, and a relative destination is
+evaluated with respect to the current build directory.  Copying
+preserves input file timestamps, and optimizes out a file if it exists
+at the destination with the same timestamp.  Copying preserves input
+permissions unless explicit permissions or ``NO_SOURCE_PERMISSIONS``
+are given (default is ``USE_SOURCE_PERMISSIONS``).
+
+If ``FOLLOW_SYMLINK_CHAIN`` is specified, ``COPY`` will recursively resolve
+the symlinks at the paths given until a real file is found, and install
+a corresponding symlink in the destination for each symlink encountered. For
+each symlink that is installed, the resolution is stripped of the directory,
+leaving only the filename, meaning that the new symlink points to a file in
+the same directory as the symlink. This feature is useful on some Unix systems,
+where libraries are installed as a chain of symlinks with version numbers, with
+less specific versions pointing to more specific versions.
+``FOLLOW_SYMLINK_CHAIN`` will install all of these symlinks and the library
+itself into the destination directory. For example, if you have the following
+directory structure:
+
+* ``/opt/foo/lib/libfoo.so.1.2.3``
+* ``/opt/foo/lib/libfoo.so.1.2 -> libfoo.so.1.2.3``
+* ``/opt/foo/lib/libfoo.so.1 -> libfoo.so.1.2``
+* ``/opt/foo/lib/libfoo.so -> libfoo.so.1``
+
+and you do:
+
+.. code-block:: cmake
+
+  file(COPY /opt/foo/lib/libfoo.so DESTINATION lib FOLLOW_SYMLINK_CHAIN)
+
+This will install all of the symlinks and ``libfoo.so.1.2.3`` itself into
+``lib``.
+
+See the :command:`install(DIRECTORY)` command for documentation of
+permissions, ``FILES_MATCHING``, ``PATTERN``, ``REGEX``, and
+``EXCLUDE`` options.  Copying directories preserves the structure
+of their content even if options are used to select a subset of
+files.
+
+The ``INSTALL`` signature differs slightly from ``COPY``: it prints
+status messages (subject to the :variable:`CMAKE_INSTALL_MESSAGE` variable),
+and ``NO_SOURCE_PERMISSIONS`` is default.
+Installation scripts generated by the :command:`install` command
+use this signature (with some undocumented options for internal use).
+
+.. _SIZE:
+
+.. code-block:: cmake
+
+  file(SIZE <filename> <variable>)
+
+Determine the file size of the ``<filename>`` and put the result in
+``<variable>`` variable. Requires that ``<filename>`` is a valid path
+pointing to a file and is readable.
+
+.. _READ_SYMLINK:
+
+.. code-block:: cmake
+
+  file(READ_SYMLINK <linkname> <variable>)
+
+This subcommand queries the symlink ``<linkname>`` and stores the path it
+points to in the result ``<variable>``.  If ``<linkname>`` does not exist or
+is not a symlink, CMake issues a fatal error.
+
+Note that this command returns the raw symlink path and does not resolve
+a relative path.  The following is an example of how to ensure that an
+absolute path is obtained:
+
+.. code-block:: cmake
+
+  set(linkname "/path/to/foo.sym")
+  file(READ_SYMLINK "${linkname}" result)
+  if(NOT IS_ABSOLUTE "${result}")
+    get_filename_component(dir "${linkname}" DIRECTORY)
+    set(result "${dir}/${result}")
+  endif()
+
+.. _CREATE_LINK:
+
+.. code-block:: cmake
+
+  file(CREATE_LINK <original> <linkname>
+       [RESULT <result>] [COPY_ON_ERROR] [SYMBOLIC])
+
+Create a link ``<linkname>`` that points to ``<original>``.
+It will be a hard link by default, but providing the ``SYMBOLIC`` option
+results in a symbolic link instead.  Hard links require that ``original``
+exists and is a file, not a directory.  If ``<linkname>`` already exists,
+it will be overwritten.
+
+The ``<result>`` variable, if specified, receives the status of the operation.
+It is set to ``0`` upon success or an error message otherwise.  If ``RESULT``
+is not specified and the operation fails, a fatal error is emitted.
+
+Specifying ``COPY_ON_ERROR`` enables copying the file as a fallback if
+creating the link fails.  It can be useful for handling situations such as
+``<original>`` and ``<linkname>`` being on different drives or mount points,
+which would make them unable to support a hard link.

 CMake constructs a set of possible installation prefixes for the
 package.  Under each prefix several directories are searched for a
 configuration file.  The tables below show the directories searched.

+Invocation
+^^^^^^^^^^
+
+The function invocation is case-insensitive. A function defined as
+
+.. code-block:: cmake
+
+  function(foo)
+    <commands>
+  endfunction()
+
+can be invoked through any of
+
+.. code-block:: cmake
+
+  foo()
+  Foo()
+  FOO()
+
+and so on. However, it is strongly recommended to stay with the
+case chosen in the function definition. Typically functions use
+all-lowercase names.
+
+Arguments
+^^^^^^^^^
+
+When the function is invoked, the recorded ``<commands>`` are first
+modified by replacing formal parameters (``${arg1}``, ...) with the
+arguments passed, and then invoked as normal commands.
+
+In addition to referencing the formal parameters you can reference the

+into the function as well as ``ARGV0``, ``ARGV1``, ``ARGV2``, ...  which
+will have the actual values of the arguments passed in.  This facilitates
+creating functions with optional arguments.
+
+Furthermore, ``ARGV`` holds the list of all arguments given to the
+function and ``ARGN`` holds the list of arguments past the last expected
+argument.  Referencing to ``ARGV#`` arguments beyond ``ARGC`` have

 The ``TARGETS`` form specifies rules for installing targets from a
-project.  There are six kinds of target files that may be installed:
-``ARCHIVE``, ``LIBRARY``, ``RUNTIME``, ``OBJECTS``, ``FRAMEWORK``, and
-``BUNDLE``. Executables are treated as ``RUNTIME`` targets, except that
-those marked with the ``MACOSX_BUNDLE`` property are treated as ``BUNDLE``
-targets on OS X.  Static libraries are treated as ``ARCHIVE`` targets,
-except that those marked with the ``FRAMEWORK`` property are treated
-as ``FRAMEWORK`` targets on OS X.
-Module libraries are always treated as ``LIBRARY`` targets.
-For non-DLL platforms shared libraries are treated as ``LIBRARY``
-targets, except that those marked with the ``FRAMEWORK`` property are
-treated as ``FRAMEWORK`` targets on OS X.  For DLL platforms the DLL
-part of a shared library is treated as a ``RUNTIME`` target and the
-corresponding import library is treated as an ``ARCHIVE`` target.
-All Windows-based systems including Cygwin are DLL platforms. Object
-libraries are always treated as ``OBJECTS`` targets.
-The ``ARCHIVE``, ``LIBRARY``, ``RUNTIME``, ``OBJECTS``, and ``FRAMEWORK``
-arguments change the type of target to which the subsequent properties
-apply. If none is given the installation properties apply to all target
-types.  If only one is given then only targets of that type will be
-installed (which can be used to install just a DLL or just an import
-library).
-
-The ``PRIVATE_HEADER``, ``PUBLIC_HEADER``, and ``RESOURCE`` arguments
-cause subsequent properties to be applied to installing a ``FRAMEWORK``
-shared library target's associated files on non-Apple platforms.  Rules
-defined by these arguments are ignored on Apple platforms because the
-associated files are installed into the appropriate locations inside
-the framework folder.  See documentation of the
-:prop_tgt:`PRIVATE_HEADER`, :prop_tgt:`PUBLIC_HEADER`, and
-:prop_tgt:`RESOURCE` target properties for details.
-
-Either ``NAMELINK_ONLY`` or ``NAMELINK_SKIP`` may be specified as a
-``LIBRARY`` option.  On some platforms a versioned shared library
-has a symbolic link such as::
-
-  lib<name>.so -> lib<name>.so.1
-
-where ``lib<name>.so.1`` is the soname of the library and ``lib<name>.so``
-is a "namelink" allowing linkers to find the library when given
-``-l<name>``.  The ``NAMELINK_ONLY`` option causes installation of only the
-namelink when a library target is installed.  The ``NAMELINK_SKIP`` option
-causes installation of library files other than the namelink when a
-library target is installed.  When neither option is given both
-portions are installed.  On platforms where versioned shared libraries
-do not have namelinks or when a library is not versioned the
-``NAMELINK_SKIP`` option installs the library and the ``NAMELINK_ONLY``
-option installs nothing.  See the :prop_tgt:`VERSION` and
-:prop_tgt:`SOVERSION` target properties for details on creating versioned
-shared libraries.
-
-The ``INCLUDES DESTINATION`` specifies a list of directories
-which will be added to the :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES`
-target property of the ``<targets>`` when exported by the
-:command:`install(EXPORT)` command.  If a relative path is
-specified, it is treated as relative to the ``$<INSTALL_PREFIX>``.

+project.  There are several kinds of target files that may be installed:
+
+``ARCHIVE``
+  Static libraries are treated as ``ARCHIVE`` targets, except those
+  marked with the ``FRAMEWORK`` property on macOS (see ``FRAMEWORK``
+  below.) For DLL platforms (all Windows-based systems including
+  Cygwin), the DLL import library is treated as an ``ARCHIVE`` target.
+
+``LIBRARY``
+  Module libraries are always treated as ``LIBRARY`` targets. For non-
+  DLL platforms shared libraries are treated as ``LIBRARY`` targets,
+  except those marked with the ``FRAMEWORK`` property on macOS (see
+  ``FRAMEWORK`` below.)
+
+``RUNTIME``
+  Executables are treated as ``RUNTIME`` objects, except those marked
+  with the ``MACOSX_BUNDLE`` property on macOS (see ``BUNDLE`` below.)
+  For DLL platforms (all Windows-based systems including Cygwin), the
+  DLL part of a shared library is treated as a ``RUNTIME`` target.
+
+``OBJECTS``
+  Object libraries (a simple group of object files) are always treated
+  as ``OBJECTS`` targets.
+
+``FRAMEWORK``
+  Both static and shared libraries marked with the ``FRAMEWORK``
+  property are treated as ``FRAMEWORK`` targets on macOS.
+
+``BUNDLE``
+  Executables marked with the :prop_tgt:`MACOSX_BUNDLE` property are treated as
+  ``BUNDLE`` targets on macOS.
+
+``PUBLIC_HEADER``
+  Any :prop_tgt:`PUBLIC_HEADER` files associated with a library are installed in
+  the destination specified by the ``PUBLIC_HEADER`` argument on non-Apple
+  platforms. Rules defined by this argument are ignored for :prop_tgt:`FRAMEWORK`
+  libraries on Apple platforms because the associated files are installed
+  into the appropriate locations inside the framework folder. See
+  :prop_tgt:`PUBLIC_HEADER` for details.
+
+``PRIVATE_HEADER``
+  Similar to ``PUBLIC_HEADER``, but for ``PRIVATE_HEADER`` files. See
+  :prop_tgt:`PRIVATE_HEADER` for details.
+
+``RESOURCE``
+  Similar to ``PUBLIC_HEADER`` and ``PRIVATE_HEADER``, but for
+  ``RESOURCE`` files. See :prop_tgt:`RESOURCE` for details.
+
+For each of these arguments given, the arguments following them only apply
+to the target or file type specified in the argument. If none is given, the
+installation properties apply to all target types. If only one is given then
+only targets of that type will be installed (which can be used to install
+just a DLL or just an import library.)
+
+For regular executables, static libraries and shared libraries, the
+``DESTINATION`` argument is not required.  For these target types, when
+``DESTINATION`` is omitted, a default destination will be taken from the
+appropriate variable from :module:`GNUInstallDirs`, or set to a built-in
+default value if that variable is not defined.  The same is true for the
+public and private headers associated with the installed targets through the
+:prop_tgt:`PUBLIC_HEADER` and :prop_tgt:`PRIVATE_HEADER` target properties.
+A destination must always be provided for module libraries, Apple bundles and
+frameworks.  A destination can be omitted for interface and object libraries,
+but they are handled differently (see the discussion of this topic toward the
+end of this section).
+
+The following table shows the target types with their associated variables and
+built-in defaults that apply when no destination is given:
+
+================== =============================== ======================
+   Target Type         GNUInstallDirs Variable        Built-In Default
+================== =============================== ======================
+``RUNTIME``        ``${CMAKE_INSTALL_BINDIR}``     ``bin``
+``LIBRARY``        ``${CMAKE_INSTALL_LIBDIR}``     ``lib``
+``ARCHIVE``        ``${CMAKE_INSTALL_LIBDIR}``     ``lib``
+``PRIVATE_HEADER`` ``${CMAKE_INSTALL_INCLUDEDIR}`` ``include``
+``PUBLIC_HEADER``  ``${CMAKE_INSTALL_INCLUDEDIR}`` ``include``
+================== =============================== ======================
+
+Projects wishing to follow the common practice of installing headers into a
+project-specific subdirectory will need to provide a destination rather than
+rely on the above.
+
+To make packages compliant with distribution filesystem layout policies, if
+projects must specify a ``DESTINATION``, it is recommended that they use a
+path that begins with the appropriate :module:`GNUInstallDirs` variable.
+This allows package maintainers to control the install destination by setting
+the appropriate cache variables.  The following example shows a static library
+being installed to the default destination provided by
+:module:`GNUInstallDirs`, but with its headers installed to a project-specific
+subdirectory that follows the above recommendation:
+
+.. code-block:: cmake
+
+  add_library(mylib STATIC ...)
+  set_target_properties(mylib PROPERTIES PUBLIC_HEADER mylib.h)
+  include(GNUInstallDirs)
+  install(TARGETS mylib
+          PUBLIC_HEADER
+            DESTINATION ${CMAKE_INSTALL_INCLUDEDIR}/myproj
+  )
+
+In addition to the common options listed above, each target can accept
+the following additional arguments:
+
+``NAMELINK_COMPONENT``
+  On some platforms a versioned shared library has a symbolic link such
+  as::
+
+    lib<name>.so -> lib<name>.so.1
+
+  where ``lib<name>.so.1`` is the soname of the library and ``lib<name>.so``
+  is a "namelink" allowing linkers to find the library when given
+  ``-l<name>``. The ``NAMELINK_COMPONENT`` option is similar to the
+  ``COMPONENT`` option, but it changes the installation component of a shared
+  library namelink if one is generated. If not specified, this defaults to the
+  value of ``COMPONENT``. It is an error to use this parameter outside of a
+  ``LIBRARY`` block.
+
+  Consider the following example:
+
+  .. code-block:: cmake
+
+    install(TARGETS mylib
+            LIBRARY
+              COMPONENT Libraries
+              NAMELINK_COMPONENT Development
+            PUBLIC_HEADER
+              COMPONENT Development
+           )
+
+  In this scenario, if you choose to install only the ``Development``
+  component, both the headers and namelink will be installed without the
+  library. (If you don't also install the ``Libraries`` component, the
+  namelink will be a dangling symlink, and projects that link to the library
+  will have build errors.) If you install only the ``Libraries`` component,
+  only the library will be installed, without the headers and namelink.
+
+  This option is typically used for package managers that have separate
+  runtime and development packages. For example, on Debian systems, the
+  library is expected to be in the runtime package, and the headers and
+  namelink are expected to be in the development package.
+
+  See the :prop_tgt:`VERSION` and :prop_tgt:`SOVERSION` target properties for
+  details on creating versioned shared libraries.
+
+``NAMELINK_ONLY``
+  This option causes the installation of only the namelink when a library
+  target is installed. On platforms where versioned shared libraries do not
+  have namelinks or when a library is not versioned, the ``NAMELINK_ONLY``
+  option installs nothing. It is an error to use this parameter outside of a
+  ``LIBRARY`` block.
+
+  When ``NAMELINK_ONLY`` is given, either ``NAMELINK_COMPONENT`` or
+  ``COMPONENT`` may be used to specify the installation component of the
+  namelink, but ``COMPONENT`` should generally be preferred.
+
+``NAMELINK_SKIP``
+  Similar to ``NAMELINK_ONLY``, but it has the opposite effect: it causes the
+  installation of library files other than the namelink when a library target
+  is installed. When neither ``NAMELINK_ONLY`` or ``NAMELINK_SKIP`` are given,
+  both portions are installed. On platforms where versioned shared libraries
+  do not have symlinks or when a library is not versioned, ``NAMELINK_SKIP``
+  installs the library. It is an error to use this parameter outside of a
+  ``LIBRARY`` block.
+
+  If ``NAMELINK_SKIP`` is specified, ``NAMELINK_COMPONENT`` has no effect. It
+  is not recommended to use ``NAMELINK_SKIP`` in conjunction with
+  ``NAMELINK_COMPONENT``.
+
+The `install(TARGETS)`_ command can also accept the following options at the
+top level:
+
+``EXPORT``
+  This option associates the installed target files with an export called
+  ``<export-name>``.  It must appear before any target options.  To actually
+  install the export file itself, call `install(EXPORT)`_, documented below.
+  See documentation of the :prop_tgt:`EXPORT_NAME` target property to change
+  the name of the exported target.
+
+``INCLUDES DESTINATION``
+  This option specifies a list of directories which will be added to the
+  :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` target property of the
+  ``<targets>`` when exported by the `install(EXPORT)`_ command. If a
+  relative path is specified, it is treated as relative to the

+Generated Installation Script
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``install()`` command generates a file, ``cmake_install.cmake``, inside
+the build directory, which is used internally by the generated install target
+and by CPack. You can also invoke this script manually with ``cmake -P``. This
+script accepts several variables:
+
+``COMPONENT``
+  Set this variable to install only a single CPack component as opposed to all
+  of them. For example, if you only want to install the ``Development``
+  component, run ``cmake -DCOMPONENT=Development -P cmake_install.cmake``.
+
+``BUILD_TYPE``
+  Set this variable to change the build type if you are using a multi-config
+  generator. For example, to install with the ``Debug`` configuration, run
+  ``cmake -DBUILD_TYPE=Debug -P cmake_install.cmake``.
+
+``DESTDIR``
+  This is an environment variable rather than a CMake variable. It allows you
+  to change the installation prefix on UNIX systems. See :envvar:`DESTDIR` for
+  details.

+Introduction
+^^^^^^^^^^^^
+
+The list subcommands ``APPEND``, ``INSERT``, ``FILTER``, ``PREPEND``,
+``POP_BACK``, ``POP_FRONT``, ``REMOVE_AT``, ``REMOVE_ITEM``,
+``REMOVE_DUPLICATES``, ``REVERSE`` and ``SORT`` may create
+new values for the list within the current CMake variable scope.  Similar to
+the :command:`set` command, the LIST command creates new variable values in
+the current scope, even if the list itself is actually defined in a parent
+scope.  To propagate the results of these operations upwards, use
+:command:`set` with ``PARENT_SCOPE``, :command:`set` with
+``CACHE INTERNAL``, or some other means of value propagation.
+
+.. note::
+
+  A list in cmake is a ``;`` separated group of strings.  To create a
+  list the set command can be used.  For example, ``set(var a b c d e)``
+  creates a list with ``a;b;c;d;e``, and ``set(var "a b c d e")`` creates a
+  string or a list with one item in it.   (Note macro arguments are not
+  variables, and therefore cannot be used in LIST commands.)
+
+.. note::
+
+  When specifying index values, if ``<element index>`` is 0 or greater, it
+  is indexed from the beginning of the list, with 0 representing the
+  first list element.  If ``<element index>`` is -1 or lesser, it is indexed
+  from the end of the list, with -1 representing the last list element.
+  Be careful when counting with negative indices: they do not start from
+  0.  -0 is equivalent to 0, the first list element.

+
+.. _JOIN:
+
+.. code-block:: cmake
+
+  list(JOIN <list> <glue> <output variable>)

+  list(SUBLIST <list> <begin> <length> <output variable>)
+

+
+.. code-block:: cmake
+
+  list(POP_BACK <list> [<out-var>...])
+
+If no variable name is given, removes exactly one element. Otherwise,

+
+.. _POP_FRONT:
+
+.. code-block:: cmake
+
+  list(POP_FRONT <list> [<out-var>...])
+
+If no variable name is given, removes exactly one element. Otherwise,
+assign the first element's value to the given variable and removes it,
+up to the last variable name given.
+
+.. _PREPEND:
+
+.. code-block:: cmake
+
+  list(PREPEND <list> [<element> ...])
+
+Insert elements to the 0th position in the list.

+   the other ones will remain the same as before the transformation.
 
-``REMOVE_DUPLICATES`` will remove duplicated items in the list.
+``<ACTION>`` specifies the action to apply to the elements of the list.
+The actions have exactly the same semantics as sub-commands of the
+:command:`string` command.  ``<ACTION>`` must be one of the following:
 
-``REVERSE`` reverses the contents of the list in-place.

+The macro invocation is case-insensitive. A macro defined as
+
+.. code-block:: cmake
+
+  macro(foo)

+  endmacro()
+
+can be invoked through any of
+
+.. code-block:: cmake

+  foo()
+  Foo()
+  FOO()
+
+and so on. However, it is strongly recommended to stay with the
+case chosen in the macro definition.  Typically macros use
+all-lowercase names.
+
+Arguments

 In addition to referencing the formal parameters you can reference the
 values ``${ARGC}`` which will be set to the number of arguments passed
 into the function as well as ``${ARGV0}``, ``${ARGV1}``, ``${ARGV2}``,
 ...  which will have the actual values of the arguments passed in.

-Macro Argument Caveats
-^^^^^^^^^^^^^^^^^^^^^^
+The ``macro`` command is very similar to the :command:`function` command.
+Nonetheless, there are a few important differences.
 
-Note that the parameters to a macro and values such as ``ARGN`` are
-not variables in the usual CMake sense.  They are string
-replacements much like the C preprocessor would do with a macro.
-Therefore you will NOT be able to use commands like::
+In a function, ``ARGN``, ``ARGC``, ``ARGV`` and ``ARGV0``, ``ARGV1``, ...
+are true variables in the usual CMake sense.  In a macro, they are not,
+they are string replacements much like the C preprocessor would do
+with a macro.  This has a number of consequences, as explained in
+the :ref:`Argument Caveats` section below.
+
+Another difference between macros and functions is the control flow.
+A function is executed by transferring control from the calling
+statement to the function body.  A macro is executed as if the macro
+body were pasted in place of the calling statement.  This has the
+consequence that a :command:`return()` in a macro body does not
+just terminate execution of the macro; rather, control is returned
+from the scope of the macro call.  To avoid confusion, it is recommended
+to avoid :command:`return()` in macros altogether.

+Argument Caveats

+
+Since ``ARGN``, ``ARGC``, ``ARGV``, ``ARGV0`` etc. are not variables,
+you will NOT be able to use commands like

  if(ARGV1) # ARGV1 is not a variable
  if(DEFINED ARGV2) # ARGV2 is not a variable
  if(ARGC GREATER 2) # ARGC is not a variable
  foreach(loop_var IN LISTS ARGN) # ARGN is not a variable
 
-In the first case, you can use ``if(${ARGV1})``.
-In the second and third case, the proper way to check if an optional
-variable was passed to the macro is to use ``if(${ARGC} GREATER 2)``.
-In the last case, you can use ``foreach(loop_var ${ARGN})`` but this

+
+  When the ``project()`` command is called from the top-level ``CMakeLists.txt``,
+  then the version is also stored in the variable :variable:`CMAKE_PROJECT_VERSION`.
+
+``DESCRIPTION <project-description-string>``
+  Optional.
+  Sets the variables
+
+  * :variable:`PROJECT_DESCRIPTION`, :variable:`<PROJECT-NAME>_DESCRIPTION`
+
+  to ``<project-description-string>``.
+  It is recommended that this description is a relatively short string,
+  usually no more than a few words.
+
+  When the ``project()`` command is called from the top-level ``CMakeLists.txt``,
+  then the description is also stored in the variable :variable:`CMAKE_PROJECT_DESCRIPTION`.
+
+``HOMEPAGE_URL <url-string>``
+  Optional.
+  Sets the variables
+

+
+  to ``<url-string>``, which should be the canonical home URL for the project.
+
+  When the ``project()`` command is called from the top-level ``CMakeLists.txt``,
+  then the URL also is stored in the variable :variable:`CMAKE_PROJECT_HOMEPAGE_URL`.
+
+``LANGUAGES <language-name>...``
+  Optional.
+  Can also be specified without ``LANGUAGES`` keyword per the first, short signature.
+
+  Selects which programming languages are needed to build the project.
+  Supported languages include ``C``, ``CXX`` (i.e.  C++), ``CUDA``, ``Fortran``, and ``ASM``.
+  By default ``C`` and ``CXX`` are enabled if no language options are given.
+  Specify language ``NONE``, or use the ``LANGUAGES`` keyword and list no languages,
+  to skip enabling any languages.
+
+  If enabling ``ASM``, list it last so that CMake can check whether
+  compilers for other languages like ``C`` work for assembly too.
+
+The variables set through the ``VERSION``, ``DESCRIPTION`` and ``HOMEPAGE_URL``
+options are intended for use as default values in package metadata and documentation.
+
+Code Injection
+^^^^^^^^^^^^^^
+
+If the :variable:`CMAKE_PROJECT_INCLUDE_BEFORE` variable is set, the file
+pointed to by that variable will be included as the first step of the
+``project()`` command.
+
+If the :variable:`CMAKE_PROJECT_INCLUDE` or
+:variable:`CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE` variables are set, the files
+they point to will be included as the last step of the ``project()`` command.
+If both are set, then :variable:`CMAKE_PROJECT_INCLUDE` will be included before

+Linking Object Libraries
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+:ref:`Object Libraries` may be used as the ``<target>`` (first) argument
+of ``target_link_libraries`` to specify dependencies of their sources
+on other libraries.  For example, the code
+
+.. code-block:: cmake
+
+  add_library(A SHARED a.c)
+  target_compile_definitions(A PUBLIC A)
+
+  add_library(obj OBJECT obj.c)
+  target_compile_definitions(obj PUBLIC OBJ)
+  target_link_libraries(obj PUBLIC A)
+
+compiles ``obj.c`` with ``-DA -DOBJ`` and establishes usage requirements
+for ``obj`` that propagate to its dependents.
+
+Normal libraries and executables may link to :ref:`Object Libraries`
+to get their objects and usage requirements.  Continuing the above
+example, the code
+
+.. code-block:: cmake
+
+  add_library(B SHARED b.c)
+  target_link_libraries(B PUBLIC obj)
+
+compiles ``b.c`` with ``-DA -DOBJ``, creates shared library ``B``
+with object files from ``b.c`` and ``obj.c``, and links ``B`` to ``A``.
+Furthermore, the code
+
+.. code-block:: cmake
+
+  add_executable(main main.c)
+  target_link_libraries(main B)
+
+compiles ``main.c`` with ``-DA -DOBJ`` and links executable ``main``
+to ``B`` and ``A``.  The object library's usage requirements are
+propagated transitively through ``B``, but its object files are not.
+
+:ref:`Object Libraries` may "link" to other object libraries to get
+usage requirements, but since they do not have a link step nothing
+is done with their object files.  Continuing from the above example,
+the code:
+
+.. code-block:: cmake
+
+  add_library(obj2 OBJECT obj2.c)
+  target_link_libraries(obj2 PUBLIC obj)
+
+  add_executable(main2 main2.c)
+  target_link_libraries(main2 obj2)
+
+compiles ``obj2.c`` with ``-DA -DOBJ``, creates executable ``main2``
+with object files from ``main2.c`` and ``obj2.c``, and links ``main2``
+to ``A``.
+
+In other words, when :ref:`Object Libraries` appear in a target's
+:prop_tgt:`INTERFACE_LINK_LIBRARIES` property they will be
+treated as :ref:`Interface Libraries`, but when they appear in
+a target's :prop_tgt:`LINK_LIBRARIES` property their object files
+will be included in the link too.

 .. contents:: Maintainer Processes:
 
+Review a Merge Request
+======================
+
+The `CMake Review Process`_ requires a maintainer to issue the ``Do: merge``
+command to integrate a merge request.  Please check at least the following:
+
+* If the MR source branch is not named well for the change it makes
+  (e.g. it is just ``master`` or the patch changed during review),
+  add a ``Topic-rename: <topic>`` trailing line to the MR description
+  to provide a better topic name.
+
+* If the MR introduces a new feature or a user-facing behavior change,
+  such as a policy, ensure that a ``Help/release/dev/$topic.rst`` file
+  is added with a release note.
+
+* If a commit changes a specific area, such as a module, its commit
+  message should have an ``area:`` prefix on its first line.
+
+* If a commit fixes a tracked issue, its commit message should have
+  a trailing line such as ``Fixes: #00000``.
+
+* Ensure that the MR adds sufficient documentation and test cases.
+
+* Ensure that the MR has been tested sufficiently.  Typically it should
+  be staged for nightly testing with ``Do: stage``.  Then manually
+  review the `CMake CDash Page`_ to verify that no regressions were
+  introduced.  (Learn to tolerate spurious failures due to idiosyncrasies
+  of various nightly builders.)
+
+* Ensure that the MR targets the ``master`` branch.  A MR intended for
+  the ``release`` branch should be based on ``release`` but still merged
+  to ``master`` first (via ``Do: merge``).  A maintainer may then merge
+  the MR topic to ``release`` manually.
+
+Maintain Current Release
+========================
+
+The ``release`` branch is used to maintain the current release or release
+candidate.  The branch is published with no version number but maintained
+using a local branch named ``release-$ver``, where ``$ver`` is the version
+number of the current release in the form ``$major.$minor``.  It is always
+merged into ``master`` before publishing.
+
+Before merging a ``$topic`` branch into ``release``, verify that the
+``$topic`` branch has already been merged to ``master`` via the usual
+``Do: merge`` process.  Then, to merge the ``$topic`` branch into
+``release``, start by creating the local branch:
+
+.. code-block:: shell
+
+  git fetch origin
+  git checkout -b release-$ver origin/release
+
+Merge the ``$topic`` branch into the local ``release-$ver`` branch, making
+sure to include a ``Merge-request: !xxxx`` footer in the commit message:
+
+.. code-block:: shell
+
+  git merge --no-ff $topic
+
+Merge the ``release-$ver`` branch to ``master``:
+
+.. code-block:: shell
+
+  git checkout master
+  git pull
+  git merge --no-ff release-$ver
+
+Review new ancestry to ensure nothing unexpected was merged to either branch:
+
+.. code-block:: shell
+
+  git log --graph --boundary origin/master..master
+  git log --graph --boundary origin/release..release-$ver
+
+Publish both ``master`` and ``release`` simultaneously:

+Commit Messages
+---------------
+
+Part of the human review is to check that each commit message is appropriate.
+The first line of the message should begin with one or two words indicating the
+area the commit applies to, followed by a colon and then a brief summary.
+Committers should aim to keep this first line short. Any subsequent lines
+should be separated from the first by a blank line and provide relevant, useful
+information.
+
+Area Prefix on Commit Messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The appropriateness of the initial word describing the area the commit applies
+to is not something the automatic robot review can judge, so it is up to the
+human reviewer to confirm that the area is specified and that it is
+appropriate. Good area words include the module name the commit is primarily
+fixing, the main C++ source file being edited, ``Help`` for generic
+documentation changes or a feature or functionality theme the changes apply to
+(e.g. ``server`` or ``Autogen``). Examples of suitable first lines of a commit
+message include:
+
+* ``Help: Fix example in cmake-buildsystem(7) manual``
+* ``FindBoost: Add support for 1.64``
+* ``Autogen: Extended mocInclude tests``
+* ``cmLocalGenerator: Explain standard flag selection logic in comments``
+
+Referencing Issues in Commit Messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the commit fixes a particular reported issue, this information should
+ideally also be part of the commit message. The recommended way to do this is
+to place a line at the end of the message in the form ``Fixes: #xxxxx`` where
+``xxxxx`` is the GitLab issue number and to separate it from the rest of the
+text by a blank line. For example::
+
+  Help: Fix FooBar example robustness issue
+
+  FooBar supports option X, but the example provided
+  would not work if Y was also specified.
+
+  Fixes: #12345
+
+GitLab will automatically create relevant links to the merge request and will
+close the issue when the commit is merged into master. GitLab understands a few
+other synonyms for ``Fixes`` and allows much more flexible forms than the
+above, but committers should aim for this format for consistency. Note that
+such details can alternatively be specified in the merge request description.
+
+Referencing Commits in Commit Messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The preferred form for references to other commits is
+``commit <shorthash> (<subject>, <date>)``, where:
+
+* ``<shorthash>``:
+  The abbreviated hash of the commit.
+
+* ``<subject>``:
+  The first line of the commit message.
+
+* ``<date>``:
+  The author date of the commit, in its original time zone, formatted as
+  ``CCYY-MM-DD``.  ``git-log(1)`` shows the original time zone by default.
+
+This may be generated with
+``git show -s --date=short --pretty="format:%h (%s, %ad)" <commit>``.
+
+If the commit is a fix for the mentioned commit, consider using a ``Fixes:``
+trailer in the commit message with the specified format. This trailer should
+not be word-wrapped. Note that if there is also an issue for what is being
+fixed, it is preferrable to link to the issue instead.
+
+If relevant, add the first release tag of CMake containing the commit after
+the ``<date>``, i.e., ``commit <shorthash> (<subject>, <date>, <tag>)``.
+
+Alternatively, the full commit ``<hash>`` may be used.
+
+Revising Commit Messages
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Reviewers are encouraged to ask the committer to amend commit messages to
+follow these guidelines, but prefer to focus on the changes themselves as a
+first priority. Maintainers will also make a check of commit messages before
+merging.

 Resolve
 =======
 
-A MR may be resolved in one of the following ways.
+The workflow used by the CMake project supports a number of different
+ways in which a MR can be moved to a resolved state.  In addition to
+the conventional practices of merging or closing a MR without merging it,
+a MR can also be moved to a quasi-resolved state pending some action.
+This may involve moving discussion to an issue or it may be the result of
+an extended period of inactivity.  These quasi-resolved states are used
+to help manage the relatively large number of MRs the project receives
+and are not an indication of the changes being rejected.  The following

+for an extended period by work in a different MR).  This is not an
+indication that there is a problem with the MR's content, it is only a

+are actively being worked on.  As a guide, the average period of inactivity
+before transitioning a MR to the expired state would be around 2 weeks,

+
+Reviewers would usually provide a message similar to the following when

+  Closing for now. @<MR-author> please re-open when ready to continue work.
+
+This is to make it clear to contributors that they are welcome to re-open
+the expired MR when they are ready to return to working on it and moving
+it forward.  In the meantime, the MR will appear as ``Closed`` in GitLab,
+but it can be differentiated from permanently closed MRs by the presence
+of the ``workflow:expired`` label.
+
+**NOTE:** Please re-open *before* pushing an update to the MR topic branch
+to ensure GitLab will still act on the association.  If changes are pushed
+before re-opening the MR, the reviewer should initiate a ``Do: check`` to
+force GitLab to act on the updates.
+
+External Discussion
+-------------------
+
+In some situations, a series of comments on a MR may develop into a more
+involved discussion, or it may become apparent that there are broader
+discussions that need to take place before the MR can move forward in an
+agreed direction.  Such discussions are better suited to GitLab issues
+rather than in a MR because MRs may be superseded by a different MR, or
+the set of changes may evolve to look quite different to the context in
+which the discussions began.  When this occurs, reviewers may ask the
+MR author to open an issue to discuss things there and they will transition
+the MR to a resolved state with the label ``workflow:external-discussion``.
+The MR will appear in GitLab as closed, but it can be differentiated from
+permanently closed MRs by the presence of the ``workflow:external-discussion``
+label.  Reviewers should leave a message clearly explaining the action
+so that the MR author understands that the MR closure is temporary and
+it is clear what actions need to happen next.  The following is an example
+of such a message, but it will usually be necessary to tailor the message
+to the individual situation::
+
+  The desired behavior here looks to be more involved than first thought.
+  Please open an issue so we can discuss the relevant details there.
+  Once the path forward is clear, we can re-open this MR and continue work.
+
+When the discussion in the associated issue runs its course and the way
+forward is clear, the MR can be re-opened again and the
+``workflow:external-discussion`` label removed.  Reviewers should ensure
+that the issue created contains a reference to the MR so that GitLab
+provides a cross-reference to link the two.

+* Do not use ``std::auto_ptr``.
 
-  The ``std::auto_ptr`` template is deprecated in C++11.  We want to use it

-* Use ``CM_EQ_DELETE;`` instead of ``= delete;``.
+Source Tree Layout
+==================
 
-  Defining functions as *deleted* is not supported in C++98.  Using
-  ``CM_EQ_DELETE`` will delete the functions if the compiler supports it and
-  give them no implementation otherwise.  Calling such a function will lead
-  to compiler errors if the compiler supports *deleted* functions and linker
-  errors otherwise.
+The CMake source tree is organized as follows.
 
-* Use ``CM_DISABLE_COPY(Class)`` to mark classes as non-copyable.
+* ``Auxiliary/``:
+  Shell and editor integration files.
 
-  The ``CM_DISABLE_COPY`` macro should be used in the private section of a
-  class to make sure that attempts to copy or assign an instance of the class
-  lead to compiler errors even if the compiler does not support *deleted*
-  functions.  As a guideline, all polymorphic classes should be made
-  non-copyable in order to avoid slicing.  Classes that are composed of or
-  derived from non-copyable classes must also be made non-copyable explicitly
-  with ``CM_DISABLE_COPY``.

 Introduction
 ============
 
-This manual is intended for reference by developers modifying the CMake
-source tree itself, and by those authoring externally-maintained modules.
-
-Adding Compile Features
-=======================
-
-CMake reports an error if a compiler whose features are known does not report
-support for a particular requested feature.  A compiler is considered to have
-known features if it reports support for at least one feature.
-
-When adding a new compile feature to CMake, it is therefore necessary to list
-support for the feature for all CompilerIds which already have one or more
-feature supported, if the new feature is available for any version of the
-compiler.
-
-When adding the first supported feature to a particular CompilerId, it is
-necessary to list support for all features known to cmake (See
-:variable:`CMAKE_C_COMPILE_FEATURES` and
-:variable:`CMAKE_CXX_COMPILE_FEATURES` as appropriate), where available for
-the compiler.  Ensure that the ``CMAKE_<LANG>_STANDARD_DEFAULT`` is set to
-the computed internal variable ``CMAKE_<LANG>_STANDARD_COMPUTED_DEFAULT``
-for compiler versions which should be supported.
-
-It is sensible to record the features for the most recent version of a
-particular CompilerId first, and then work backwards.  It is sensible to
-try to create a continuous range of versions of feature releases of the
-compiler.  Gaps in the range indicate incorrect features recorded for
-intermediate releases.
-
-Generally, features are made available for a particular version if the
-compiler vendor documents availability of the feature with that
-version.  Note that sometimes partially implemented features appear to
-be functional in previous releases (such as ``cxx_constexpr`` in GNU 4.6,
-though availability is documented in GNU 4.7), and sometimes compiler vendors
-document availability of features, though supporting infrastructure is
-not available (such as ``__has_feature(cxx_generic_lambdas)`` indicating
-non-availability in Clang 3.4, though it is documented as available, and
-fixed in Clang 3.5).  Similar cases for other compilers and versions
-need to be investigated when extending CMake to support them.
-
-When a vendor releases a new version of a known compiler which supports
-a previously unsupported feature, and there are already known features for
-that compiler, the feature should be listed as supported in CMake for
-that version of the compiler as soon as reasonably possible.
-
-Standard-specific/compiler-specific variables such
-``CMAKE_CXX98_COMPILE_FEATURES`` are deliberately not documented.  They
-only exist for the compiler-specific implementation of adding the ``-std``
-compile flag for compilers which need that.
-
-Help
-====
-
-The ``Help`` directory contains CMake help manual source files.
-They are written using the `reStructuredText`_ markup syntax and
-processed by `Sphinx`_ to generate the CMake help manuals.
-
-.. _`reStructuredText`: http://docutils.sourceforge.net/docs/ref/rst/introduction.html
-.. _`Sphinx`: http://sphinx-doc.org
-
-Markup Constructs
------------------
-
-In addition to using Sphinx to generate the CMake help manuals, we
-also use a C++-implemented document processor to print documents for
-the ``--help-*`` command-line help options.  It supports a subset of
-reStructuredText markup.  When authoring or modifying documents,
-please verify that the command-line help looks good in addition to the
-Sphinx-generated html and man pages.
-
-The command-line help processor supports the following constructs
-defined by reStructuredText, Sphinx, and a CMake extension to Sphinx.
-
-..
- Note: This list must be kept consistent with the cmRST implementation.
-
-CMake Domain directives
- Directives defined in the `CMake Domain`_ for defining CMake
- documentation objects are printed in command-line help output as
- if the lines were normal paragraph text with interpretation.
-
-CMake Domain interpreted text roles
- Interpreted text roles defined in the `CMake Domain`_ for
- cross-referencing CMake documentation objects are replaced by their
- link text in command-line help output.  Other roles are printed
- literally and not processed.
-
-``code-block`` directive
- Add a literal code block without interpretation.  The command-line
- help processor prints the block content without the leading directive
- line and with common indentation replaced by one space.
-
-``include`` directive
- Include another document source file.  The command-line help
- processor prints the included document inline with the referencing
- document.
-
-literal block after ``::``
- A paragraph ending in ``::`` followed by a blank line treats
- the following indented block as literal text without interpretation.
- The command-line help processor prints the ``::`` literally and
- prints the block content with common indentation replaced by one
- space.
-
-``note`` directive
- Call out a side note.  The command-line help processor prints the
- block content as if the lines were normal paragraph text with
- interpretation.
-
-``parsed-literal`` directive
- Add a literal block with markup interpretation.  The command-line
- help processor prints the block content without the leading
- directive line and with common indentation replaced by one space.
-
-``productionlist`` directive
- Render context-free grammar productions.  The command-line help
- processor prints the block content as if the lines were normal
- paragraph text with interpretation.
-
-``replace`` directive
- Define a ``|substitution|`` replacement.
- The command-line help processor requires a substitution replacement
- to be defined before it is referenced.
-
-``|substitution|`` reference
- Reference a substitution replacement previously defined by
- the ``replace`` directive.  The command-line help processor
- performs the substitution and replaces all newlines in the
- replacement text with spaces.
-
-``toctree`` directive
- Include other document sources in the Table-of-Contents
- document tree.  The command-line help processor prints
- the referenced documents inline as part of the referencing
- document.
-
-Inline markup constructs not listed above are printed literally in the
-command-line help output.  We prefer to use inline markup constructs that
-look correct in source form, so avoid use of \\-escapes in favor of inline
-literals when possible.
-
-Explicit markup blocks not matching directives listed above are removed from
-command-line help output.  Do not use them, except for plain ``..`` comments
-that are removed by Sphinx too.
+This manual is intended for reference by developers working with
+:manual:`cmake-language(7)` code, whether writing their own modules,
+authoring their own build systems, or working on CMake itself.
 
-Note that nested indentation of blocks is not recognized by the
-command-line help processor.  Therefore:
-
-* Explicit markup blocks are recognized only when not indented
-  inside other blocks.
-
-* Literal blocks after paragraphs ending in ``::`` but not
-  at the top indentation level may consume all indented lines
-  following them.
-
-Try to avoid these cases in practice.
-
-CMake Domain
-------------
-
-CMake adds a `Sphinx Domain`_ called ``cmake``, also called the
-"CMake Domain".  It defines several "object" types for CMake
-documentation:
-
-``command``
- A CMake language command.
-
-``generator``
- A CMake native build system generator.
- See the :manual:`cmake(1)` command-line tool's ``-G`` option.
-
-``manual``
- A CMake manual page, like this :manual:`cmake-developer(7)` manual.
-
-``module``
- A CMake module.
- See the :manual:`cmake-modules(7)` manual
- and the :command:`include` command.
-
-``policy``
- A CMake policy.
- See the :manual:`cmake-policies(7)` manual
- and the :command:`cmake_policy` command.
-
-``prop_cache, prop_dir, prop_gbl, prop_sf, prop_inst, prop_test, prop_tgt``
- A CMake cache, directory, global, source file, installed file, test,
- or target property, respectively.  See the :manual:`cmake-properties(7)`
- manual and the :command:`set_property` command.
-
-``variable``
- A CMake language variable.
- See the :manual:`cmake-variables(7)` manual
- and the :command:`set` command.
-
-Documentation objects in the CMake Domain come from two sources.
-First, the CMake extension to Sphinx transforms every document named
-with the form ``Help/<type>/<file-name>.rst`` to a domain object with
-type ``<type>``.  The object name is extracted from the document title,
-which is expected to be of the form::
-
- <object-name>
- -------------
-
-and to appear at or near the top of the ``.rst`` file before any other
-lines starting in a letter, digit, or ``<``.  If no such title appears
-literally in the ``.rst`` file, the object name is the ``<file-name>``.
-If a title does appear, it is expected that ``<file-name>`` is equal
-to ``<object-name>`` with any ``<`` and ``>`` characters removed.
-
-Second, the CMake Domain provides directives to define objects inside
-other documents:
-
-.. code-block:: rst
-
- .. command:: <command-name>
-
-  This indented block documents <command-name>.
-
- .. variable:: <variable-name>
-
-  This indented block documents <variable-name>.
-
-Object types for which no directive is available must be defined using
-the first approach above.
-
-.. _`Sphinx Domain`: http://sphinx-doc.org/domains.html
-
-Cross-References
-----------------
-
-Sphinx uses reStructuredText interpreted text roles to provide
-cross-reference syntax.  The `CMake Domain`_ provides for each
-domain object type a role of the same name to cross-reference it.
-CMake Domain roles are inline markup of the forms::
-
- :type:`name`
- :type:`text <name>`
-
-where ``type`` is the domain object type and ``name`` is the
-domain object name.  In the first form the link text will be
-``name`` (or ``name()`` if the type is ``command``) and in
-the second form the link text will be the explicit ``text``.
-For example, the code:
-
-.. code-block:: rst
-
- * The :command:`list` command.
- * The :command:`list(APPEND)` sub-command.
- * The :command:`list() command <list>`.
- * The :command:`list(APPEND) sub-command <list>`.
- * The :variable:`CMAKE_VERSION` variable.
- * The :prop_tgt:`OUTPUT_NAME_<CONFIG>` target property.
-
-produces:
-
-* The :command:`list` command.
-* The :command:`list(APPEND)` sub-command.
-* The :command:`list() command <list>`.
-* The :command:`list(APPEND) sub-command <list>`.
-* The :variable:`CMAKE_VERSION` variable.
-* The :prop_tgt:`OUTPUT_NAME_<CONFIG>` target property.
-
-Note that CMake Domain roles differ from Sphinx and reStructuredText
-convention in that the form ``a<b>``, without a space preceding ``<``,
-is interpreted as a name instead of link text with an explicit target.
-This is necessary because we use ``<placeholders>`` frequently in
-object names like ``OUTPUT_NAME_<CONFIG>``.  The form ``a <b>``,
-with a space preceding ``<``, is still interpreted as a link text
-with an explicit target.
-
-Style
------
-
-Style: Section Headers
-^^^^^^^^^^^^^^^^^^^^^^
-
-When marking section titles, make the section decoration line as long as
-the title text.  Use only a line below the title, not above. For
-example:
-
-.. code-block:: rst
-
-  Title Text
-  ----------
-
-Capitalize the first letter of each non-minor word in the title.
-
-The section header underline character hierarchy is
-
-* ``#``: Manual group (part) in the master document
-* ``*``: Manual (chapter) title
-* ``=``: Section within a manual
-* ``-``: Subsection or `CMake Domain`_ object document title
-* ``^``: Subsubsection or `CMake Domain`_ object document section
-* ``"``: Paragraph or `CMake Domain`_ object document subsection
-
-Style: Whitespace
-^^^^^^^^^^^^^^^^^
-
-Use two spaces for indentation.  Use two spaces between sentences in
-prose.
-
-Style: Line Length
-^^^^^^^^^^^^^^^^^^
-
-Prefer to restrict the width of lines to 75-80 columns.  This is not a
-hard restriction, but writing new paragraphs wrapped at 75 columns
-allows space for adding minor content without significant re-wrapping of
-content.
-
-Style: Prose
-^^^^^^^^^^^^
-
-Use American English spellings in prose.
-
-Style: Starting Literal Blocks
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Prefer to mark the start of literal blocks with ``::`` at the end of
-the preceding paragraph. In cases where the following block gets
-a ``code-block`` marker, put a single ``:`` at the end of the preceding
-paragraph.
-
-Style: CMake Command Signatures
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Command signatures should be marked up as plain literal blocks, not as
-cmake ``code-blocks``.
-
-Signatures are separated from preceding content by a section header.
-That is, use:
-
-.. code-block:: rst
-
-  ... preceding paragraph.
-
-  Normal Libraries
-  ^^^^^^^^^^^^^^^^
-
-  ::
-
-    add_library(<lib> ...)
-
-  This signature is used for ...
-
-Signatures of commands should wrap optional parts with square brackets,
-and should mark list of optional arguments with an ellipsis (``...``).
-Elements of the signature which are specified by the user should be
-specified with angle brackets, and may be referred to in prose using
-``inline-literal`` syntax.
-
-Style: Boolean Constants
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-Use "``OFF``" and "``ON``" for boolean values which can be modified by
-the user, such as :prop_tgt:`POSITION_INDEPENDENT_CODE`. Such properties
-may be "enabled" and "disabled". Use "``True``" and "``False``" for
-inherent values which can't be modified after being set, such as the
-:prop_tgt:`IMPORTED` property of a build target.
-
-Style: Inline Literals
-^^^^^^^^^^^^^^^^^^^^^^
-
-Mark up references to keywords in signatures, file names, and other
-technical terms with ``inline-literal`` syntax, for example:
-
-.. code-block:: rst
-
-  If ``WIN32`` is used with :command:`add_executable`, the
-  :prop_tgt:`WIN32_EXECUTABLE` target property is enabled. That command
-  creates the file ``<name>.exe`` on Windows.
-
-Style: Cross-References
-^^^^^^^^^^^^^^^^^^^^^^^
-
-Mark up linkable references as links, including repeats.
-An alternative, which is used by wikipedia
-(`<http://en.wikipedia.org/wiki/WP:REPEATLINK>`_),
-is to link to a reference only once per article. That style is not used
-in CMake documentation.
-
-Style: Referencing CMake Concepts
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If referring to a concept which corresponds to a property, and that
-concept is described in a high-level manual, prefer to link to the
-manual section instead of the property. For example:
-
-.. code-block:: rst
-
-  This command creates an :ref:`Imported Target <Imported Targets>`.
-
-instead of:
-
-.. code-block:: rst
-
-  This command creates an :prop_tgt:`IMPORTED` target.
-
-The latter should be used only when referring specifically to the
-property.
-
-References to manual sections are not automatically created by creating
-a section, but code such as:
-
-.. code-block:: rst
-
-  .. _`Imported Targets`:
-
-creates a suitable anchor.  Use an anchor name which matches the name
-of the corresponding section.  Refer to the anchor using a
-cross-reference with specified text.
-
-Imported Targets need the ``IMPORTED`` term marked up with care in
-particular because the term may refer to a command keyword
-(``IMPORTED``), a target property (:prop_tgt:`IMPORTED`), or a
-concept (:ref:`Imported Targets`).
-
-Where a property, command or variable is related conceptually to others,
-by for example, being related to the buildsystem description, generator
-expressions or Qt, each relevant property, command or variable should
-link to the primary manual, which provides high-level information.  Only
-particular information relating to the command should be in the
-documentation of the command.
-
-Style: Referencing CMake Domain Objects
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-When referring to `CMake Domain`_ objects such as properties, variables,
-commands etc, prefer to link to the target object and follow that with
-the type of object it is.  For example:
-
-.. code-block:: rst
-
-  Set the :prop_tgt:`AUTOMOC` target property to ``ON``.
-
-Instead of
-
-.. code-block:: rst
-
-  Set the target property :prop_tgt:`AUTOMOC` to ``ON``.
-
-The ``policy`` directive is an exception, and the type us usually
-referred to before the link:
-
-.. code-block:: rst
-
-  If policy :prop_tgt:`CMP0022` is set to ``NEW`` the behavior is ...
-
-However, markup self-references with ``inline-literal`` syntax.
-For example, within the :command:`add_executable` command
-documentation, use
-
-.. code-block:: rst
-
-  ``add_executable``
-
-not
-
-.. code-block:: rst
-
-  :command:`add_executable`
-
-which is used elsewhere.
-
-Modules
-=======
-
-The ``Modules`` directory contains CMake-language ``.cmake`` module files.
-
-Module Documentation
---------------------
-
-To document CMake module ``Modules/<module-name>.cmake``, modify
-``Help/manual/cmake-modules.7.rst`` to reference the module in the
-``toctree`` directive, in sorted order, as::
-
- /module/<module-name>
-
-Then add the module document file ``Help/module/<module-name>.rst``
-containing just the line::
-
- .. cmake-module:: ../../Modules/<module-name>.cmake
-
-The ``cmake-module`` directive will scan the module file to extract
-reStructuredText markup from comment blocks that start in ``.rst:``.
-At the top of ``Modules/<module-name>.cmake``, begin with the following
-license notice:
-
-.. code-block:: cmake
-
- # Distributed under the OSI-approved BSD 3-Clause License.  See accompanying
- # file Copyright.txt or https://cmake.org/licensing for details.
-
-After this notice, add a *BLANK* line.  Then, add documentation using
-a :ref:`Line Comment` block of the form:
-
-.. code-block:: cmake
-
- #.rst:
- # <module-name>
- # -------------
- #
- # <reStructuredText documentation of module>
-
-or a :ref:`Bracket Comment` of the form:
-
-::
-
- #[[.rst:
- <module-name>
- -------------
-
- <reStructuredText documentation of module>
- #]]
-
-Any number of ``=`` may be used in the opening and closing brackets
-as long as they match.  Content on the line containing the closing
-bracket is excluded if and only if the line starts in ``#``.
-
-Additional such ``.rst:`` comments may appear anywhere in the module file.
-All such comments must start with ``#`` in the first column.
-
-For example, a ``Modules/Findxxx.cmake`` module may contain:
-
-::
-
- # Distributed under the OSI-approved BSD 3-Clause License.  See accompanying
- # file Copyright.txt or https://cmake.org/licensing for details.
-
- #.rst:
- # FindXxx
- # -------

-Available informational expressions are:
+And here two nested string-valued expressions:

+
+The following string-valued generator expressions are available:

+Escaped Characters
+------------------
+
+String literals to escape the special meaning a character would otherwise have:
+
+``$<ANGLE-R>``
+  A literal ``>``. Used for example to compare strings that contain a ``>``.
+``$<COMMA>``
+  A literal ``,``. Used for example to compare strings which contain a ``,``.

+
+Conditional Expressions
+-----------------------
+
+Conditional generator expressions depend on a boolean condition
+that must be ``0`` or ``1``.
+
+``$<condition:true_string>``
+  Evaluates to ``true_string`` if ``condition`` is ``1``.
+  Otherwise evaluates to the empty string.
+
+``$<IF:condition,true_string,false_string>``
+  Evaluates to ``true_string`` if ``condition`` is ``1``.
+  Otherwise evaluates to ``false_string``.
+
+Typically, the ``condition`` is a :ref:`boolean generator expression
+<Boolean Generator Expressions>`.  For instance,
+
+.. code-block:: cmake
+
+  $<$<CONFIG:Debug>:DEBUG_MODE>
+
+expands to ``DEBUG_MODE`` when the ``Debug`` configuration is used, and
+otherwise expands to the empty string.
+
+.. _`String Transforming Generator Expressions`:
+
+String Transformations
+----------------------
+
+``$<JOIN:list,string>``
+  Joins the list with the content of ``string``.
+``$<REMOVE_DUPLICATES:list>``
+  Removes duplicated items in the given ``list``.
+``$<FILTER:list,INCLUDE|EXCLUDE,regex>``
+  Includes or removes items from ``list`` that match the regular expression ``regex``.
+``$<LOWER_CASE:string>``
+  Content of ``string`` converted to lower case.
+``$<UPPER_CASE:string>``
+  Content of ``string`` converted to upper case.
+
+``$<GENEX_EVAL:expr>``
+  Content of ``expr`` evaluated as a generator expression in the current
+  context. This enables consumption of generator expressions whose
+  evaluation results itself in generator expressions.
+``$<TARGET_GENEX_EVAL:tgt,expr>``
+  Content of ``expr`` evaluated as a generator expression in the context of
+  ``tgt`` target. This enables consumption of custom target properties that
+  themselves contain generator expressions.
+
+  Having the capability to evaluate generator expressions is very useful when
+  you want to manage custom properties supporting generator expressions.
+  For example:
+
+  .. code-block:: cmake
+
+    add_library(foo ...)
+
+    set_property(TARGET foo PROPERTY
+      CUSTOM_KEYS $<$<CONFIG:DEBUG>:FOO_EXTRA_THINGS>
+    )
+
+    add_custom_target(printFooKeys
+      COMMAND ${CMAKE_COMMAND} -E echo $<TARGET_PROPERTY:foo,CUSTOM_KEYS>
+    )
+

+ Environment variables have global scope in a CMake process.
+ They are never cached.
+
+References
+ `Variable References`_ have the form ``$ENV{<variable>}``.

+For cross-compiling to iOS, tvOS, or watchOS, the :generator:`Xcode`
+generator is recommended.  The :generator:`Unix Makefiles` or

+
+Any of the three systems can be targeted by setting the
+:variable:`CMAKE_SYSTEM_NAME` variable to a value from the table below.
+By default, the latest Device SDK is chosen.  As for all Apple platforms,
+a different SDK (e.g. a simulator) can be selected by setting the
+:variable:`CMAKE_OSX_SYSROOT` variable, although this should rarely be
+necessary (see :ref:`Switching Between Device and Simulator` below).
+A list of available SDKs can be obtained by running ``xcodebuild -showsdks``.

+watchOS  watchOS           watchos              watchsimulator
+=======  ================= ==================== ================
+
+For example, to create a CMake configuration for iOS, the following
+command is sufficient:
+
+.. code-block:: console
+
+  cmake .. -GXcode -DCMAKE_SYSTEM_NAME=iOS
+
+Variable :variable:`CMAKE_OSX_ARCHITECTURES` can be used to set architectures
+for both device and simulator. Variable :variable:`CMAKE_OSX_DEPLOYMENT_TARGET`
+can be used to set an iOS/tvOS/watchOS deployment target.
+
+Next configuration will install fat 5 architectures iOS library
+and add the ``-miphoneos-version-min=9.3``/``-mios-simulator-version-min=9.3``

+
+Code Signing
+^^^^^^^^^^^^
+
+Some build artifacts for the embedded Apple platforms require mandatory
+code signing.  If the :generator:`Xcode` generator is being used and
+code signing is required or desired, the development team ID can be
+specified via the ``CMAKE_XCODE_ATTRIBUTE_DEVELOPMENT_TEAM`` CMake variable.
+This team ID will then be included in the generated Xcode project.
+By default, CMake avoids the need for code signing during the internal
+configuration phase (i.e compiler ID and feature detection).
+
+.. _`Switching Between Device and Simulator`:
+
+Switching Between Device and Simulator
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When configuring for any of the embedded platforms, one can target either
+real devices or the simulator.  Both have their own separate SDK, but CMake
+only supports specifying a single SDK for the configuration phase.  This
+means the developer must select one or the other at configuration time.
+When using the :generator:`Xcode` generator, this is less of a limitation
+because Xcode still allows you to build for either a device or a simulator,
+even though configuration was only performed for one of the two.  From
+within the Xcode IDE, builds are performed for the selected "destination"
+platform.  When building from the command line, the desired sdk can be
+specified directly by passing a ``-sdk`` option to the underlying build
+tool (``xcodebuild``).  For example:
+
+.. code-block:: console
+
+  $ cmake --build ... -- -sdk iphonesimulator
+
+Please note that checks made during configuration were performed against
+the configure-time SDK and might not hold true for other SDKs.  Commands
+like :command:`find_package`, :command:`find_library`, etc. store and use
+details only for the configured SDK/platform, so they can be problematic
+if wanting to switch between device and simulator builds. You can follow
+the next rules to make device + simulator configuration work:

+buildsystem generator CMake.  The above `Synopsis`_ lists various actions
+the tool can perform as described in sections below.
+
+To build a software project with CMake, `Generate a Project Buildsystem`_.
+Optionally use **cmake** to `Build a Project`_, `Install a Project`_ or just
+run the corresponding build tool (e.g. ``make``) directly.  **cmake** can also
+be used to `View Help`_.
+
+The other actions are meant for use by software developers writing

+
+Introduction to CMake Buildsystems
+==================================
+
+A *buildsystem* describes how to build a project's executables and libraries
+from its source code using a *build tool* to automate the process.  For
+example, a buildsystem may be a ``Makefile`` for use with a command-line
+``make`` tool or a project file for an Integrated Development Environment
+(IDE).  In order to avoid maintaining multiple such buildsystems, a project
+may specify its buildsystem abstractly using files written in the
+:manual:`CMake language <cmake-language(7)>`.  From these files CMake
+generates a preferred buildsystem locally for each user through a backend
+called a *generator*.
+
+To generate a buildsystem with CMake, the following must be selected:
+
+Source Tree
+  The top-level directory containing source files provided by the project.
+  The project specifies its buildsystem using files as described in the
+  :manual:`cmake-language(7)` manual, starting with a top-level file named
+  ``CMakeLists.txt``.  These files specify build targets and their
+  dependencies as described in the :manual:`cmake-buildsystem(7)` manual.
+
+Build Tree
+  The top-level directory in which buildsystem files and build output
+  artifacts (e.g. executables and libraries) are to be stored.
+  CMake will write a ``CMakeCache.txt`` file to identify the directory
+  as a build tree and store persistent information such as buildsystem
+  configuration options.
+
+  To maintain a pristine source tree, perform an *out-of-source* build
+  by using a separate dedicated build tree.  An *in-source* build in
+  which the build tree is placed in the same directory as the source
+  tree is also supported, but discouraged.
+
+Generator
+  This chooses the kind of buildsystem to generate.  See the
+  :manual:`cmake-generators(7)` manual for documentation of all generators.
+  Run ``cmake --help`` to see a list of generators available locally.
+  Optionally use the ``-G`` option below to specify a generator, or simply
+  accept the default CMake chooses for the current platform.
+
+  When using one of the :ref:`Command-Line Build Tool Generators`

+
+
+Generate a Project Buildsystem
+==============================
+
+Run CMake with one of the following command signatures to specify the
+source and build trees and generate a buildsystem:
+
+``cmake [<options>] <path-to-source>``
+  Uses the current working directory as the build tree, and
+  ``<path-to-source>`` as the source tree.  The specified path may
+  be absolute or relative to the current working directory.
+  The source tree must contain a ``CMakeLists.txt`` file and must
+  *not* contain a ``CMakeCache.txt`` file because the latter
+  identifies an existing build tree.  For example:
+
+  .. code-block:: console
+
+    $ mkdir build ; cd build
+    $ cmake ../src
+
+``cmake [<options>] <path-to-existing-build>``
+  Uses ``<path-to-existing-build>`` as the build tree, and loads the
+  path to the source tree from its ``CMakeCache.txt`` file, which must
+  have already been generated by a previous run of CMake.  The specified
+  path may be absolute or relative to the current working directory.
+  For example:
+
+  .. code-block:: console
+
+    $ cd build
+    $ cmake .
+
+``cmake [<options>] -S <path-to-source> -B <path-to-build>``
+  Uses ``<path-to-build>`` as the build tree and ``<path-to-source>``
+  as the source tree.  The specified paths may be absolute or relative
+  to the current working directory.  The source tree must contain a
+  ``CMakeLists.txt`` file.  The build tree will be created automatically
+  if it does not already exist.  For example:
 
-CMake is a cross-platform build system generator.  Projects specify
-their build process with platform-independent CMake listfiles included
-in each directory of a source tree with the name CMakeLists.txt.
-Users build a project by using CMake to generate a build system for a
-native tool on their platform.
+  .. code-block:: console
+
+    $ cmake -S src -B build
+
+In all cases the ``<options>`` may be zero or more of the `Options`_ below.
+
+After generating a buildsystem one may use the corresponding native
+build tool to build the project.  For example, after using the
+:generator:`Unix Makefiles` generator one may run ``make`` directly:
+
+  .. code-block:: console
+
+    $ make
+    $ make install
+
+Alternatively, one may use **cmake** to `Build a Project`_ by
+automatically choosing and invoking the appropriate native build tool.

 Description
 ===========
 
-The "cpack" executable is the CMake packaging program.
-CMake-generated build trees created for projects that use the
-INSTALL_* commands have packaging support.  This program will generate
-the package.
+The **cpack** executable is the CMake packaging program.  It generates
+installers and source packages in a variety of formats.
 
-CMake is a cross-platform build system generator.  Projects specify
-their build process with platform-independent CMake listfiles included
-in each directory of a source tree with the name CMakeLists.txt.
-Users build a project by using CMake to generate a build system for a
-native tool on their platform.
+For each installer or package format, **cpack** has a specific backend,
+called "generator". A generator is responsible for generating the required
+inputs and invoking the specific package creation tools. These installer
+or package generators are not to be confused with the makefile generators
+of the :manual:`cmake <cmake(1)>` command.
+
+All supported generators are specified in the :manual:`cpack-generators
+<cpack-generators(7)>` manual.  The command ``cpack --help`` prints a
+list of generators supported for the target platform.  Which of them are
+to be used can be selected through the :variable:`CPACK_GENERATOR` variable
+or through the command-line option ``-G``.
+
+The **cpack** program is steered by a configuration file written in the
+:manual:`CMake language <cmake-language(7)>`. Unless chosen differently
+through the command-line option ``--config``, the file ``CPackConfig.cmake``
+in the current directory is used.
+
+In the standard CMake workflow, the file ``CPackConfig.cmake`` is generated
+by the :manual:`cmake <cmake(1)>` executable, provided the :module:`CPack`
+module is included by the project's ``CMakeLists.txt`` file.
 
 Options
 =======
 
-``-G <generator>``
- Use the specified generator to generate package.
-
- CPack may support multiple native packaging systems on certain
- platforms.  A generator is responsible for generating input files
- for particular system and invoking that systems.  Possible generator
- names are specified in the Generators section.
+``-G <generators>``
+  ``<generators>`` is a :ref:`semicolon-separated list <CMake Language Lists>`
+  of generator names.  ``cpack`` will iterate through this list and produce
+  package(s) in that generator's format according to the details provided in
+  the ``CPackConfig.cmake`` configuration file.  If this option is not given,
+  the :variable:`CPACK_GENERATOR` variable determines the default set of
+  generators that will be used.
 
 ``-C <Configuration>``
- Specify the project configuration
-
- This option specifies the configuration that the project was build
- with, for example 'Debug', 'Release'.
+  Specify the project configuration to be packaged (e.g. ``Debug``,
+  ``Release``, etc.).  When the CMake project uses a multi-configuration
+  generator such as Xcode or Visual Studio, this option is needed to tell
+  ``cpack`` which built executables to include in the package.
 
 ``-D <var>=<value>``
- Set a CPack variable.
+  Set a CPack variable.  This will override any value set for ``<var>`` in the
+  input file read by ``cpack``.
 
- Set a variable that can be used by the generator.
+``--config <configFile>``
+  Specify the configuration file read by ``cpack`` to provide the packaging
+  details.  By default, ``CPackConfig.cmake`` in the current directory will
+  be used.
 
-``--config <config file>``
- Specify the config file.
-
- Specify the config file to use to create the package.  By default
- CPackConfig.cmake in the current directory will be used.
-
-``--verbose,-V``
- enable verbose output
-
- Run cpack with verbose output.
+``--verbose, -V``
+  Run ``cpack`` with verbose output.  This can be used to show more details
+  from the package generation tools and is suitable for project developers.
 
 ``--debug``
- enable debug output (for CPack developers)
-
- Run cpack with debug output (for CPack developers).
-
-``-P <package name>``
- override/define CPACK_PACKAGE_NAME
-
- If the package name is not specified on cpack command line
- thenCPack.cmake defines it as CMAKE_PROJECT_NAME
-
-``-R <package version>``
- override/define CPACK_PACKAGE_VERSION
-
- If version is not specified on cpack command line thenCPack.cmake
- defines it from CPACK_PACKAGE_VERSION_[MAJOR|MINOR|PATCH]look into
- CPack.cmake for detail
-
-``-B <package directory>``
- override/define CPACK_PACKAGE_DIRECTORY
-
- The directory where CPack will be doing its packaging work.The
- resulting package will be found there.  Inside this directoryCPack
- creates '_CPack_Packages' sub-directory which is theCPack temporary

+Label and Subproject Summary
+============================
+
+CTest prints timing summary information for each ``LABEL`` and subproject
+associated with the tests run. The label time summary will not include labels
+that are mapped to subprojects.
+
+When the :prop_test:`PROCESSORS` test property is set, CTest will display a
+weighted test timing result in label and subproject summaries. The time is
+reported with `sec*proc` instead of just `sec`.
+
+The weighted time summary reported for each label or subproject ``j``
+is computed as::
+
+  Weighted Time Summary for Label/Subproject j =
+      sum(raw_test_time[j,i] * num_processors[j,i], i=1...num_tests[j])
+
+  for labels/subprojects j=1...total
+
+where:
+
+* ``raw_test_time[j,i]``: Wall-clock time for the ``i`` test
+  for the ``j`` label or subproject
+* ``num_processors[j,i]``: Value of the CTest :prop_test:`PROCESSORS` property
+  for the ``i`` test for the ``j`` label or subproject
+* ``num_tests[j]``: Number of tests associated with the ``j`` label or subproject
+* ``total``: Total number of labels or subprojects that have at least one test run
+
+Therefore, the weighted time summary for each label or subproject represents
+the amount of time that CTest gave to run the tests for each label or
+subproject and gives a good representation of the total expense of the tests
+for each label or subproject when compared to other labels or subprojects.
+
+For example, if ``SubprojectA`` showed ``100 sec*proc`` and ``SubprojectB`` showed
+``10 sec*proc``, then CTest allocated approximately 10 times the CPU/core time
+to run the tests for ``SubprojectA`` than for ``SubprojectB`` (e.g. so if effort
+is going to be expended to reduce the cost of the test suite for the whole
+project, then reducing the cost of the test suite for ``SubprojectA`` would
+likely have a larger impact than effort to reduce the cost of the test suite
+for ``SubprojectB``).

+Qt version detection
+^^^^^^^^^^^^^^^^^^^^
+
+:prop_tgt:`AUTOMOC` enabled targets need to know the Qt major and minor
+version they're working with.  The major version usually is provided by the
+``INTERFACE_QT_MAJOR_VERSION`` property of the ``Qt[45]Core`` library,
+that the target links to.  To find the minor version, CMake builds a list of
+available Qt versions from
+
+- ``Qt5Core_VERSION_MAJOR`` and ``Qt5Core_VERSION_MINOR`` variables
+  (usually set by ``find_package(Qt5...)``)
+- ``Qt5Core_VERSION_MAJOR`` and ``Qt5Core_VERSION_MINOR`` directory properties
+- ``QT_VERSION_MAJOR`` and ``QT_VERSION_MINOR``  variables
+  (usually set by ``find_package(Qt4...)``)
+- ``QT_VERSION_MAJOR`` and ``QT_VERSION_MINOR``  directory properties
+
+in the context of the :command:`add_executable` or :command:`add_library` call.
+
+Assumed  ``INTERFACE_QT_MAJOR_VERSION`` is a valid number, the first
+entry in the list with a matching major version is taken.  If no matching major
+version was found, an error is generated.
+If  ``INTERFACE_QT_MAJOR_VERSION`` is not a valid number, the first
+entry in the list is taken.
 
-Additional command line options for moc can be set via the
-:prop_tgt:`AUTOMOC_MOC_OPTIONS` property.
+A ``find_package(Qt[45]...)`` call sets the ``QT/Qt5Core_VERSION_MAJOR/MINOR``
+variables.  If the call is in a different context than the
+:command:`add_executable` or :command:`add_library` call, e.g. in a function,
+then the version variables might not be available to the :prop_tgt:`AUTOMOC`
+enabled target.
+In that case the version variables can be forwarded from the
+`find_package(Qt[45]...)` calling context to the :command:`add_executable`
+or :command:`add_library` calling context as directory properties.
+The following Qt5 example demonstrates the procedure.

+Header and source file processing
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+target's sources for include statements of the form
+
+.. code-block:: c++
+
+  #include "ui_<ui_base>.h"
+
+Once such an include statement is found in a file, CMake searches for the
+``uic`` input file ``<ui_base>.ui``
+
+- in the vicinity of the file and
+- in the :prop_tgt:`AUTOUIC_SEARCH_PATHS` of the target.
+
+If the ``<ui_base>.ui`` file was found, ``uic`` is called on it to generate
+``ui_<ui_base>.h`` in the directory
+
+- ``<AUTOGEN_BUILD_DIR>/include`` for single configuration generators or in
+- ``<AUTOGEN_BUILD_DIR>/include_<CONFIG>`` for
+  :prop_gbl:`multi configuration <GENERATOR_IS_MULTI_CONFIG>` generators.
+
+Where ``<AUTOGEN_BUILD_DIR>`` is the value of the target property
+:prop_tgt:`AUTOGEN_BUILD_DIR`.
+
+The include directory is automatically added to the target's
+:prop_tgt:`INCLUDE_DIRECTORIES`.

 CMAKE_CROSSCOMPILING
 --------------------
 
-Is CMake currently cross compiling.
+Intended to indicate whether CMake is cross compiling, but note limitations
+discussed below.
 
-This variable will be set to true by CMake if CMake is cross
-compiling.  Specifically if the build platform is different from the
-target platform.
+This variable will be set to true by CMake if the :variable:`CMAKE_SYSTEM_NAME`
+variable has been set manually (i.e. in a toolchain file or as a cache entry
+from the :manual:`cmake <cmake(1)>` command line). In most cases, manually
+setting :variable:`CMAKE_SYSTEM_NAME` will only be done when cross compiling,
+since it will otherwise be given the same value as
+:variable:`CMAKE_HOST_SYSTEM_NAME` if not manually set, which is correct for
+the non-cross-compiling case. In the event that :variable:`CMAKE_SYSTEM_NAME`
+is manually set to the same value as :variable:`CMAKE_HOST_SYSTEM_NAME`, then
+``CMAKE_CROSSCOMPILING`` will still be set to true.
+
+Another case to be aware of is that builds targeting Apple platforms other than
+macOS are handled differently to other cross compiling scenarios. Rather than
+relying on :variable:`CMAKE_SYSTEM_NAME` to select the target platform, Apple
+device builds use :variable:`CMAKE_OSX_SYSROOT` to select the appropriate SDK,
+which indirectly determines the target platform. Furthermore, when using the
+:generator:`Xcode` generator, developers can switch between device and
+simulator builds at build time rather than having a single
+choice at configure time, so the concept
+of whether the build is cross compiling or not is more complex. Therefore, the
+use of ``CMAKE_CROSSCOMPILING`` is not recommended for projects targeting Apple
+devices.

+
+DO NOT USE THESE FUNCTIONS AT CONFIGURE TIME (from ``CMakeLists.txt``)!
+Instead, invoke them from an :command:`install(CODE)` or
+:command:`install(SCRIPT)` rule.
+
+.. code-block:: cmake
+
+  fixup_bundle(<app> <libs> <dirs>)
+
+Fix up ``<app>`` bundle in-place and make it standalone, such that it can be
+drag-n-drop copied to another machine and run on that machine as long
+as all of the system libraries are compatible.
+
+If you pass plugins to ``fixup_bundle`` as the libs parameter, you should

+
+As an optional parameter (``IGNORE_ITEM``) a list of file names can be passed,

+
+.. code-block:: cmake
+
+  copy_and_fixup_bundle(<src> <dst> <libs> <dirs>)
+
+Makes a copy of the bundle ``<src>`` at location ``<dst>`` and then fixes up
+the new copied bundle in-place at ``<dst>``.
+
+.. code-block:: cmake
+
+  verify_app(<app>)
+
+Verifies that an application ``<app>`` appears valid based on running

+is not verified.
+
+As an optional parameter (``IGNORE_ITEM``) a list of file names can be passed,

+file or an ``error:`` prefixed string if it could not be determined.
+
+.. code-block:: cmake
+
+  get_dotapp_dir(<exe> <dotapp_dir_var>)
+
+Returns the nearest parent dir whose name ends with ``.app`` given the

+
+The returned directory may or may not exist.
+
+.. code-block:: cmake

+Scans ``<bundle>`` bundle recursively for all ``<exes_var>`` executable
+files and accumulates them into a variable.
+
+.. code-block:: cmake
+
+  get_item_key(<item> <key_var>)
+
+Given ``<item>`` file name, generate ``<key_var>`` key that should be unique
+considering the set of libraries that need copying or fixing up to
+make a bundle standalone.  This is essentially the file name including
+extension with ``.`` replaced by ``_``
+
+This key is used as a prefix for CMake variables so that we can
+associate a set of variables with a given item based on its key.
+
+.. code-block:: cmake
+
+  clear_bundle_keys(<keys_var>)
+
+Loop over the ``<keys_var>`` list of keys, clearing all the variables
+associated with each key.  After the loop, clear the list of keys itself.
+
+Caller of ``get_bundle_keys`` should call ``clear_bundle_keys`` when done with
+list of keys.
+
+.. code-block:: cmake
+
+  set_bundle_key_values(<keys_var> <context> <item> <exepath> <dirs>
+                        <copyflag> [<rpaths>])
+
+Add ``<keys_var>`` key to the list (if necessary) for the given item.
+If added, also set all the variables associated with that key.
+
+.. code-block:: cmake
+
+  get_bundle_keys(<app> <libs> <dirs> <keys_var>)
+
+Loop over all the executable and library files within ``<app>`` bundle (and
+given as extra ``<libs>``) and accumulate a list of keys representing
+them.  Set values associated with each key such that we can loop over
+all of them and copy prerequisite libs into the bundle and then do
+appropriate ``install_name_tool`` fixups.
+
+As an optional parameter (``IGNORE_ITEM``) a list of file names can be passed,
+which are then ignored
+(e.g. ``IGNORE_ITEM "vcredist_x86.exe;vcredist_x64.exe"``)
+
+.. code-block:: cmake
+
+  copy_resolved_item_into_bundle(<resolved_item> <resolved_embedded_item>)
+
+Copy a resolved item into the bundle if necessary.
+Copy is not necessary, if the ``<resolved_item>`` is "the same as" the
+``<resolved_embedded_item>``.
+
+.. code-block:: cmake
+
+  copy_resolved_framework_into_bundle(<resolved_item> <resolved_embedded_item>)
+
+Copy a resolved framework into the bundle if necessary.
+Copy is not necessary, if the ``<resolved_item>`` is "the same as" the
+``<resolved_embedded_item>``.
+
+By default, ``BU_COPY_FULL_FRAMEWORK_CONTENTS`` is not set.  If you want
+full frameworks embedded in your bundles, set
+``BU_COPY_FULL_FRAMEWORK_CONTENTS`` to ``ON`` before calling fixup_bundle.  By
+default, ``COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE`` copies the framework
+dylib itself plus the framework ``Resources`` directory.
+
+.. code-block:: cmake
+
+  fixup_bundle_item(<resolved_embedded_item> <exepath> <dirs>)
+
+Get the direct/non-system prerequisites of the ``<resolved_embedded_item>``.
+For each prerequisite, change the way it is referenced to the value of
+the ``_EMBEDDED_ITEM`` keyed variable for that prerequisite.  (Most likely
+changing to an ``@executable_path`` style reference.)
+
+This function requires that the ``<resolved_embedded_item>`` be ``inside``
+the bundle already.  In other words, if you pass plugins to ``fixup_bundle``
+as the libs parameter, you should install them or copy them into the
+bundle before calling ``fixup_bundle``.  The ``libs`` parameter is a list of
+libraries that must be fixed up, but that cannot be determined by
+otool output analysis.  (i.e., ``plugins``)
+
+Also, change the id of the item being fixed up to its own
+``_EMBEDDED_ITEM`` value.
+
+Accumulate changes in a local variable and make *one* call to
+``install_name_tool`` at the end of the function with all the changes at
+once.
+
+If the ``BU_CHMOD_BUNDLE_ITEMS`` variable is set then bundle items will be
+marked writable before ``install_name_tool`` tries to change them.
+
+.. code-block:: cmake
+
+  verify_bundle_prerequisites(<bundle> <result_var> <info_var>)
+
+Verifies that the sum of all prerequisites of all files inside the
+bundle are contained within the bundle or are ``system`` libraries,
+presumed to exist everywhere.
+
+As an optional parameter (``IGNORE_ITEM``) a list of file names can be passed,
+which are then ignored
+(e.g. ``IGNORE_ITEM "vcredist_x86.exe;vcredist_x64.exe"``)
+
+.. code-block:: cmake
+
+  verify_bundle_symlinks(<bundle> <result_var> <info_var>)
+
+Verifies that any symlinks found in the ``<bundle>`` bundle point to other files
+that are already also in the bundle...  Anything that points to an
+external file causes this function to fail the verification.

+.. command:: find_dependency
+
+  The ``find_dependency()`` macro wraps a :command:`find_package` call for
+  a package dependency::
+
+    find_dependency(<dep> [...])
+
+  It is designed to be used in a
+  :ref:`Package Configuration File <Config File Packages>`
+  (``<PackageName>Config.cmake``).  ``find_dependency`` forwards the correct
+  parameters for ``QUIET`` and ``REQUIRED`` which were passed to
+  the original :command:`find_package` call.  Any additional arguments
+  specified are forwarded to :command:`find_package`.
+
+  If the dependency could not be found it sets an informative diagnostic
+  message and calls :command:`return` to end processing of the calling
+  package configuration file and return to the :command:`find_package`
+  command that loaded it.
+
+  .. note::
+
+    The call to :command:`return` makes this macro unsuitable to call
+    from :ref:`Find Modules`.

-# In a ``FooConfig.cmake`` file there may be code like this to make the install

-#    set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
-#    set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )

-#    #...logic to determine installedPrefix from the own location...
-#    set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )
-#
-# All 4 options shown above are not sufficient, since the first 3 hardcode the
-# absolute directory locations, and the 4th case works only if the logic to
-# determine the ``installedPrefix`` is correct, and if ``CONFIG_INSTALL_DIR``
-# contains a relative path, which in general cannot be guaranteed.  This has the

-# Windows and OSX, where users are used to choose the install location of a
-# binary package at install time, independent from how
-# :variable:`CMAKE_INSTALL_PREFIX` was set at build/cmake time.
-#
-# Using ``configure_package_config_file`` helps.  If used correctly, it makes
-# the resulting ``FooConfig.cmake`` file relocatable.  Usage:
-#
-# 1. write a ``FooConfig.cmake.in`` file as you are used to
-# 2. insert a line containing only the string ``@PACKAGE_INIT@``
-# 3. instead of ``set(FOO_DIR "@SOME_INSTALL_DIR@")``, use
-#    ``set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")`` (this must be after the
-#    ``@PACKAGE_INIT@`` line)
-# 4. instead of using the normal :command:`configure_file()`, use
-#    ``configure_package_config_file()``
-#
-#
-#
-# The ``<input>`` and ``<output>`` arguments are the input and output file, the
-# same way as in :command:`configure_file()`.
-#
-# The ``<path>`` given to ``INSTALL_DESTINATION`` must be the destination where
-# the ``FooConfig.cmake`` file will be installed to.  This path can either be
-# absolute, or relative to the ``INSTALL_PREFIX`` path.
-#
-# The variables ``<var1>`` to ``<varN>`` given as ``PATH_VARS`` are the
-# variables which contain install destinations.  For each of them the macro will
-# create a helper variable ``PACKAGE_<var...>``.  These helper variables must be
-# used in the ``FooConfig.cmake.in`` file for setting the installed location.
-# They are calculated by ``configure_package_config_file`` so that they are
-# always relative to the installed location of the package.  This works both for
-# relative and also for absolute locations.  For absolute locations it works
-# only if the absolute location is a subdirectory of ``INSTALL_PREFIX``.
-#
-# If the ``INSTALL_PREFIX`` argument is passed, this is used as base path to
-# calculate all the relative paths.  The ``<path>`` argument must be an absolute
-# path.  If this argument is not passed, the :variable:`CMAKE_INSTALL_PREFIX`
-# variable will be used instead.  The default value is good when generating a
-# FooConfig.cmake file to use your package from the install tree.  When
-# generating a FooConfig.cmake file to use your package from the build tree this
-# option should be used.
-#
-# By default ``configure_package_config_file`` also generates two helper macros,
-# ``set_and_check()`` and ``check_required_components()`` into the
-# ``FooConfig.cmake`` file.
-#
-# ``set_and_check()`` should be used instead of the normal ``set()`` command for
-# setting directories and file locations.  Additionally to setting the variable
-# it also checks that the referenced file or directory actually exists and fails
-# with a ``FATAL_ERROR`` otherwise.  This makes sure that the created
-# ``FooConfig.cmake`` file does not contain wrong references.
-# When using the ``NO_SET_AND_CHECK_MACRO``, this macro is not generated
-# into the ``FooConfig.cmake`` file.
-#
-# ``check_required_components(<package_name>)`` should be called at the end of
-# the ``FooConfig.cmake`` file if the package supports components.  This macro
-# checks whether all requested, non-optional components have been found, and if
-# this is not the case, sets the ``Foo_FOUND`` variable to ``FALSE``, so that
-# the package is considered to be not found.  It does that by testing the
-# ``Foo_<Component>_FOUND`` variables for all requested required components.
-# When using the ``NO_CHECK_REQUIRED_COMPONENTS_MACRO`` option, this macro is
-# not generated into the ``FooConfig.cmake`` file.
-#
-# For an example see below the documentation for
-# :command:`write_basic_package_version_file()`.
-#
-# Generating a Package Version File
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# .. command:: write_basic_package_version_file
-#
-#  Create a version file for a project::
-#
-#    write_basic_package_version_file(<filename>
-#      [VERSION <major.minor.patch>]
-#      COMPATIBILITY <AnyNewerVersion|SameMajorVersion|ExactVersion> )
-#
-#
-# Writes a file for use as ``<package>ConfigVersion.cmake`` file to
-# ``<filename>``.  See the documentation of :command:`find_package()` for
-# details on this.
-#
-# ``<filename>`` is the output filename, it should be in the build tree.
-# ``<major.minor.patch>`` is the version number of the project to be installed.
-#
-# If no ``VERSION`` is given, the :variable:`PROJECT_VERSION` variable is used.
-# If this hasn't been set, it errors out.
-#
-# The ``COMPATIBILITY`` mode ``AnyNewerVersion`` means that the installed
-# package version will be considered compatible if it is newer or exactly the
-# same as the requested version.  This mode should be used for packages which
-# are fully backward compatible, also across major versions.
-# If ``SameMajorVersion`` is used instead, then the behaviour differs from
-# ``AnyNewerVersion`` in that the major version number must be the same as
-# requested, e.g.  version 2.0 will not be considered compatible if 1.0 is
-# requested.  This mode should be used for packages which guarantee backward
-# compatibility within the same major version.
-# If ``ExactVersion`` is used, then the package is only considered compatible if
-# the requested version matches exactly its own version number (not considering
-# the tweak version).  For example, version 1.2.3 of a package is only
-# considered compatible to requested version 1.2.3.  This mode is for packages
-# without compatibility guarantees.
-# If your project has more elaborated version matching rules, you will need to
-# write your own custom ``ConfigVersion.cmake`` file instead of using this
-# macro.
-#
-# Internally, this macro executes :command:`configure_file()` to create the
-# resulting version file.  Depending on the ``COMPATIBLITY``, either the file
-# ``BasicConfigVersion-SameMajorVersion.cmake.in`` or
-# ``BasicConfigVersion-AnyNewerVersion.cmake.in`` is used.  Please note that
-# these two files are internal to CMake and you should not call
-# :command:`configure_file()` on them yourself, but they can be used as starting
-# point to create more sophisticted custom ``ConfigVersion.cmake`` files.

+Helpers functions for creating config files that can be included by other

+
+Adds the :command:`configure_package_config_file()` and
+:command:`write_basic_package_version_file()` commands.
+
+Generating a Package Configuration File
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. command:: configure_package_config_file
+
+ Create a config file for a project::
+
+   configure_package_config_file(<input> <output>

+     [NO_CHECK_REQUIRED_COMPONENTS_MACRO]
+     [INSTALL_PREFIX <path>]
+     )
+
+``configure_package_config_file()`` should be used instead of the plain
+:command:`configure_file()` command when creating the ``<PackageName>Config.cmake``
+or ``<PackageName>-config.cmake`` file for installing a project or library.
+It helps making the resulting package relocatable by avoiding hardcoded paths
+in the installed ``Config.cmake`` file.
+
+In a ``FooConfig.cmake`` file there may be code like this to make the install
+destinations know to the using project:
+
+.. code-block:: cmake
+
+   set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
+   set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
+   set(FOO_ICONS_DIR   "@CMAKE_INSTALL_PREFIX@/share/icons" )
+   #...logic to determine installedPrefix from the own location...
+   set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )
+
+All 4 options shown above are not sufficient, since the first 3 hardcode the
+absolute directory locations, and the 4th case works only if the logic to
+determine the ``installedPrefix`` is correct, and if ``CONFIG_INSTALL_DIR``
+contains a relative path, which in general cannot be guaranteed.  This has the

+
+``check_required_components(<PackageName>)`` should be called at the end of
+the ``FooConfig.cmake`` file. This macro checks whether all requested,
+non-optional components have been found, and if this is not the case, sets
+the ``Foo_FOUND`` variable to ``FALSE``, so that the package is considered to
+be not found.  It does that by testing the ``Foo_<Component>_FOUND``
+variables for all requested required components.  This macro should be
+called even if the package doesn't provide any components to make sure
+users are not specifying components erroneously.  When using the
+``NO_CHECK_REQUIRED_COMPONENTS_MACRO`` option, this macro is not generated
+into the ``FooConfig.cmake`` file.
+
+For an example see below the documentation for
+:command:`write_basic_package_version_file()`.
+
+Generating a Package Version File
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. command:: write_basic_package_version_file
+
+ Create a version file for a project::
+
+   write_basic_package_version_file(<filename>
+     [VERSION <major.minor.patch>]
+     COMPATIBILITY <AnyNewerVersion|SameMajorVersion|SameMinorVersion|ExactVersion>
+     [ARCH_INDEPENDENT] )
+
+
+Writes a file for use as ``<PackageName>ConfigVersion.cmake`` file to
+``<filename>``.  See the documentation of :command:`find_package()` for
+details on this.
+
+``<filename>`` is the output filename, it should be in the build tree.
+``<major.minor.patch>`` is the version number of the project to be installed.
+
+If no ``VERSION`` is given, the :variable:`PROJECT_VERSION` variable is used.
+If this hasn't been set, it errors out.
+
+The ``COMPATIBILITY`` mode ``AnyNewerVersion`` means that the installed
+package version will be considered compatible if it is newer or exactly the
+same as the requested version.  This mode should be used for packages which
+are fully backward compatible, also across major versions.
+If ``SameMajorVersion`` is used instead, then the behaviour differs from
+``AnyNewerVersion`` in that the major version number must be the same as
+requested, e.g.  version 2.0 will not be considered compatible if 1.0 is
+requested.  This mode should be used for packages which guarantee backward
+compatibility within the same major version.
+If ``SameMinorVersion`` is used, the behaviour is the same as
+``SameMajorVersion``, but both major and minor version must be the same as
+requested, e.g version 0.2 will not be compatible if 0.1 is requested.
+If ``ExactVersion`` is used, then the package is only considered compatible if
+the requested version matches exactly its own version number (not considering
+the tweak version).  For example, version 1.2.3 of a package is only
+considered compatible to requested version 1.2.3.  This mode is for packages
+without compatibility guarantees.
+If your project has more elaborated version matching rules, you will need to
+write your own custom ``ConfigVersion.cmake`` file instead of using this
+macro.
+
+If ``ARCH_INDEPENDENT`` is given, the installed package version will be
+considered compatible even if it was built for a different architecture than
+the requested architecture.  Otherwise, an architecture check will be performed,
+and the package will be considered compatible only if the architecture matches
+exactly.  For example, if the package is built for a 32-bit architecture, the
+package is only considered compatible if it is used on a 32-bit architecture,
+unless ``ARCH_INDEPENDENT`` is given, in which case the package is considered
+compatible on any architecture.
+
+.. note:: ``ARCH_INDEPENDENT`` is intended for header-only libraries or similar
+   packages with no binaries.
+
+Internally, this macro executes :command:`configure_file()` to create the
+resulting version file.  Depending on the ``COMPATIBILITY``, the corresponding
+``BasicConfigVersion-<COMPATIBILITY>.cmake.in`` file is used.
+Please note that these files are internal to CMake and you should not call
+:command:`configure_file()` on them yourself, but they can be used as starting
+point to create more sophisticted custom ``ConfigVersion.cmake`` files.

-# CPack
-# -----
-#
-# Build binary and source package installers.
-#
-# Variables common to all CPack generators
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The
-# CPack module generates binary and source installers in a variety of
-# formats using the cpack program.  Inclusion of the CPack module adds
-# two new targets to the resulting makefiles, package and
-# package_source, which build the binary and source installers,
-# respectively.  The generated binary installers contain everything
-# installed via CMake's INSTALL command (and the deprecated
-# INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
-#
-# For certain kinds of binary installers (including the graphical
-# installers on Mac OS X and Windows), CPack generates installers that
-# allow users to select individual application components to install.
-# See CPackComponent module for that.
-#
-# The CPACK_GENERATOR variable has different meanings in different
-# contexts.  In your CMakeLists.txt file, CPACK_GENERATOR is a *list of
-# generators*: when run with no other arguments, CPack will iterate over
-# that list and produce one package for each generator.  In a
-# CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming
-# a single generator*.  If you need per-cpack- generator logic to
-# control *other* cpack settings, then you need a
-# CPACK_PROJECT_CONFIG_FILE.
-#
-# The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
-# See the top level file CMakeCPackOptions.cmake.in for an example.
-#
-# If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
-# per-generator basis.  It only need contain overrides.
-#
-# Here's how it works:
-#
-# * cpack runs
-# * it includes CPackConfig.cmake
-# * it iterates over the generators listed in that file's
-#   CPACK_GENERATOR list variable (unless told to use just a
-#   specific one via -G on the command line...)
-# * foreach generator, it then
-#
-#   - sets CPACK_GENERATOR to the one currently being iterated
-#   - includes the CPACK_PROJECT_CONFIG_FILE
-#   - produces the package for that generator
-#
-# This is the key: For each generator listed in CPACK_GENERATOR in
-# CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to
-# *the one currently being used* and then include the
-# CPACK_PROJECT_CONFIG_FILE.
-#
-# Before including this CPack module in your CMakeLists.txt file, there
-# are a variety of variables that can be set to customize the resulting
-# installers.  The most commonly-used variables are:
-#
-# .. variable:: CPACK_PACKAGE_NAME
-#
-#  The name of the package (or application). If not specified, defaults to
-#  the project name.
-#
-# .. variable:: CPACK_PACKAGE_VENDOR
-#
-#  The name of the package vendor. (e.g., "Kitware").
-#
-# .. variable:: CPACK_PACKAGE_DIRECTORY
-#
-#  The directory in which CPack is doing its packaging. If it is not set
-#  then this will default (internally) to the build dir. This variable may
-#  be defined in CPack config file or from the cpack command line option
-#  "-B". If set the command line option override the value found in the
-#  config file.
-#
-# .. variable:: CPACK_PACKAGE_VERSION_MAJOR
-#
-#  Package major Version
-#
-# .. variable:: CPACK_PACKAGE_VERSION_MINOR
-#
-#  Package minor Version
-#
-# .. variable:: CPACK_PACKAGE_VERSION_PATCH
-#
-#  Package patch Version
-#
-# .. variable:: CPACK_PACKAGE_DESCRIPTION_FILE
-#
-#  A text file used to describe the project. Used, for example, the
-#  introduction screen of a CPack-generated Windows installer to describe
-#  the project.
-#
-# .. variable:: CPACK_PACKAGE_DESCRIPTION_SUMMARY
-#
-#  Short description of the project (only a few words). Default value is::
-#
-#    ${PROJECT_DESCRIPTION}
-#
-#  if DESCRIPTION has given to the project() call or
-#  CMake generated string with PROJECT_NAME otherwise.
-#
-# .. variable:: CPACK_PACKAGE_FILE_NAME
-#
-#  The name of the package file to generate, not including the
-#  extension. For example, cmake-2.6.1-Linux-i686.  The default value is::
-#
-#   ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.
-#
-# .. variable:: CPACK_PACKAGE_INSTALL_DIRECTORY
-#
-#  Installation directory on the target system. This may be used by some
-#  CPack generators like NSIS to create an installation directory e.g.,
-#  "CMake 2.5" below the installation prefix. All installed element will be
-#  put inside this directory.
-#
-# .. variable:: CPACK_PACKAGE_ICON
-#
-#  A branding image that will be displayed inside the installer (used by GUI
-#  installers).
-#
-# .. variable:: CPACK_PACKAGE_CHECKSUM
-#
-#  An algorithm that will be used to generate additional file with checksum
-#  of the package. Output file name will be::
-#
-#     ${CPACK_PACKAGE_FILE_NAME}.${CPACK_PACKAGE_CHECKSUM}
-#
-#  Supported algorithms are those listed by the
-#  :ref:`string(\<HASH\>) <Supported Hash Algorithms>`
-#  command.
-#
-# .. variable:: CPACK_PROJECT_CONFIG_FILE
-#
-#  CPack-time project CPack configuration file. This file included at cpack
-#  time, once per generator after CPack has set CPACK_GENERATOR to the
-#  actual generator being used. It allows per-generator setting of CPACK_*
-#  variables at cpack time.
-#
-# .. variable:: CPACK_RESOURCE_FILE_LICENSE
-#
-#  License to be embedded in the installer. It will typically be displayed
-#  to the user by the produced installer (often with an explicit "Accept"
-#  button, for graphical installers) prior to installation. This license
-#  file is NOT added to installed file but is used by some CPack generators
-#  like NSIS. If you want to install a license file (may be the same as this
-#  one) along with your project you must add an appropriate CMake INSTALL
-#  command in your CMakeLists.txt.
-#
-# .. variable:: CPACK_RESOURCE_FILE_README
-#
-#  ReadMe file to be embedded in the installer. It typically describes in
-#  some detail the purpose of the project during the installation. Not all
-#  CPack generators uses this file.
-#
-# .. variable:: CPACK_RESOURCE_FILE_WELCOME
-#
-#  Welcome file to be embedded in the installer. It welcomes users to this
-#  installer.  Typically used in the graphical installers on Windows and Mac
-#  OS X.
-#
-# .. variable:: CPACK_MONOLITHIC_INSTALL
-#
-#  Disables the component-based installation mechanism. When set the

+CPack
+-----
+
+Build binary and source package installers.
+
+Introduction
+^^^^^^^^^^^^
+
+The CPack module generates a file ``CPackConfig.cmake`` intended for
+use in a subsequent run of  the :manual:`cpack <cpack(1)>` program
+where it steers the generation of installers or/and source packages.
+
+Inclusion of the CPack module adds two new build targets, ``package``
+and ``package_source``, which build the binary and source installers
+respectively.  The generated binary installers contain everything
+installed via CMake's :command:`install` command (and the deprecated
+commands :command:`install_files`, :command:`install_programs`, and
+:command:`install_targets`).
+
+For certain kinds of binary installers (including the graphical
+installers on macOS and Windows), CPack generates installers that
+allow users to select individual application components to install.
+See :module:`CPackComponent` module for further details.
+
+CPack Generators
+^^^^^^^^^^^^^^^^
+
+The :variable:`CPACK_GENERATOR` variable has different meanings in different
+contexts.  In a ``CMakeLists.txt`` file, :variable:`CPACK_GENERATOR` is a
+*list of generators*: and when :manual:`cpack <cpack(1)>` is run with no other
+arguments, it will iterate over that list and produce one package for each
+generator.  In a :variable:`CPACK_PROJECT_CONFIG_FILE`,
+:variable:`CPACK_GENERATOR` is a *string naming a single generator*.  If you
+need per-cpack-generator logic to control *other* cpack settings, then you
+need a :variable:`CPACK_PROJECT_CONFIG_FILE`.
+
+The CMake source tree itself contains a :variable:`CPACK_PROJECT_CONFIG_FILE`.
+See the top level file ``CMakeCPackOptions.cmake.in`` for an example.
+
+If set, the :variable:`CPACK_PROJECT_CONFIG_FILE` is included automatically
+on a per-generator basis.  It only need contain overrides.
+
+Here's how it works:
+
+* :manual:`cpack <cpack(1)>` runs
+* it includes ``CPackConfig.cmake``
+* it iterates over the generators given by the ``-G`` command line option,
+  or if no such option was specified, over the list of generators given by
+  the :variable:`CPACK_GENERATOR` variable set in the ``CPackConfig.cmake``
+  input file.
+* foreach generator, it then
+
+  - sets :variable:`CPACK_GENERATOR` to the one currently being iterated
+  - includes the :variable:`CPACK_PROJECT_CONFIG_FILE`
+  - produces the package for that generator
+
+This is the key: For each generator listed in :variable:`CPACK_GENERATOR` in
+``CPackConfig.cmake``, cpack will *reset* :variable:`CPACK_GENERATOR`
+internally to *the one currently being used* and then include the
+:variable:`CPACK_PROJECT_CONFIG_FILE`.
+
+Variables common to all CPack Generators
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before including this CPack module in your ``CMakeLists.txt`` file, there
+are a variety of variables that can be set to customize the resulting
+installers.  The most commonly-used variables are:
+
+.. variable:: CPACK_PACKAGE_NAME
+
+  The name of the package (or application).  If not specified, it defaults to
+  the project name.
+
+.. variable:: CPACK_PACKAGE_VENDOR
+
+  The name of the package vendor. (e.g., "Kitware").  The default is "Humanity".
+
+.. variable:: CPACK_PACKAGE_DIRECTORY
+
+  The directory in which CPack is doing its packaging.  If it is not set
+  then this will default (internally) to the build dir.  This variable may
+  be defined in a CPack config file or from the :manual:`cpack <cpack(1)>`
+  command line option ``-B``.  If set, the command line option overrides the
+  value found in the config file.
+
+.. variable:: CPACK_PACKAGE_VERSION_MAJOR
+
+  Package major version.  This variable will always be set, but its default
+  value depends on whether or not version details were given to the
+  :command:`project` command in the top level CMakeLists.txt file.  If version
+  details were given, the default value will be
+  :variable:`CMAKE_PROJECT_VERSION_MAJOR`.  If no version details were given,
+  a default version of 0.1.1 will be assumed, leading to
+  ``CPACK_PACKAGE_VERSION_MAJOR`` having a default value of 0.
+
+.. variable:: CPACK_PACKAGE_VERSION_MINOR
+
+  Package minor version.  The default value is determined based on whether or
+  not version details were given to the :command:`project` command in the top
+  level CMakeLists.txt file.  If version details were given, the default
+  value will be :variable:`CMAKE_PROJECT_VERSION_MINOR`, but if no minor
+  version component was specified then ``CPACK_PACKAGE_VERSION_MINOR`` will be
+  left unset.  If no project version was given at all, a default version of
+  0.1.1 will be assumed, leading to ``CPACK_PACKAGE_VERSION_MINOR`` having a
+  default value of 1.
+
+.. variable:: CPACK_PACKAGE_VERSION_PATCH
+
+  Package patch version.  The default value is determined based on whether or
+  not version details were given to the :command:`project` command in the top
+  level CMakeLists.txt file.  If version details were given, the default
+  value will be :variable:`CMAKE_PROJECT_VERSION_PATCH`, but if no patch
+  version component was specified then ``CPACK_PACKAGE_VERSION_PATCH`` will be
+  left unset.  If no project version was given at all, a default version of
+  0.1.1 will be assumed, leading to ``CPACK_PACKAGE_VERSION_PATCH`` having a
+  default value of 1.
+
+.. variable:: CPACK_PACKAGE_DESCRIPTION
+
+  A description of the project, used in places such as the introduction
+  screen of CPack-generated Windows installers.  If not set, the value of
+  this variable is populated from the file named by
+  :variable:`CPACK_PACKAGE_DESCRIPTION_FILE`.
+
+.. variable:: CPACK_PACKAGE_DESCRIPTION_FILE
+
+  A text file used to describe the project when
+  :variable:`CPACK_PACKAGE_DESCRIPTION` is not explicitly set.  The default
+  value for ``CPACK_PACKAGE_DESCRIPTION_FILE`` points to a built-in template
+  file ``Templates/CPack.GenericDescription.txt``.
+
+.. variable:: CPACK_PACKAGE_DESCRIPTION_SUMMARY
+
+  Short description of the project (only a few words).  If the
+  :variable:`CMAKE_PROJECT_DESCRIPTION` variable is set, it is used as the
+  default value, otherwise the default will be a string generated by CMake
+  based on :variable:`CMAKE_PROJECT_NAME`.
+
+.. variable:: CPACK_PACKAGE_HOMEPAGE_URL
+
+  Project homepage URL.  The default value is taken from the
+  :variable:`CMAKE_PROJECT_HOMEPAGE_URL` variable, which is set by the top
+  level :command:`project` command, or else the default will be empty if no
+  URL was provided to :command:`project`.
+
+.. variable:: CPACK_PACKAGE_FILE_NAME
+
+  The name of the package file to generate, not including the
+  extension.  For example, ``cmake-2.6.1-Linux-i686``.  The default value
+  is::
+
+    ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}
+
+.. variable:: CPACK_PACKAGE_INSTALL_DIRECTORY
+
+  Installation directory on the target system. This may be used by some
+  CPack generators like NSIS to create an installation directory e.g.,
+  "CMake 2.5" below the installation prefix.  All installed elements will be
+  put inside this directory.
+
+.. variable:: CPACK_PACKAGE_ICON
+
+  A branding image that will be displayed inside the installer (used by GUI
+  installers).
+
+.. variable:: CPACK_PACKAGE_CHECKSUM
+
+  An algorithm that will be used to generate an additional file with the
+  checksum of the package.  The output file name will be::
+
+    ${CPACK_PACKAGE_FILE_NAME}.${CPACK_PACKAGE_CHECKSUM}
+
+  Supported algorithms are those listed by the
+  :ref:`string(\<HASH\>) <Supported Hash Algorithms>` command.
+
+.. variable:: CPACK_PROJECT_CONFIG_FILE
+
+  CPack-time project CPack configuration file.  This file is included at cpack
+  time, once per generator after CPack has set :variable:`CPACK_GENERATOR`
+  to the actual generator being used.  It allows per-generator setting of
+  ``CPACK_*`` variables at cpack time.
+
+.. variable:: CPACK_RESOURCE_FILE_LICENSE
+
+  License to be embedded in the installer.  It will typically be displayed
+  to the user by the produced installer (often with an explicit "Accept"
+  button, for graphical installers) prior to installation.  This license
+  file is NOT added to the installed files but is used by some CPack generators
+  like NSIS.  If you want to install a license file (may be the same as this
+  one) along with your project, you must add an appropriate CMake
+  :command:`install` command in your ``CMakeLists.txt``.
+
+.. variable:: CPACK_RESOURCE_FILE_README
+
+  ReadMe file to be embedded in the installer.  It typically describes in
+  some detail the purpose of the project during the installation.  Not all
+  CPack generators use this file.
+
+.. variable:: CPACK_RESOURCE_FILE_WELCOME
+
+  Welcome file to be embedded in the installer.  It welcomes users to this
+  installer.  Typically used in the graphical installers on Windows and Mac
+  OS X.
+
+.. variable:: CPACK_MONOLITHIC_INSTALL
+
+  Disables the component-based installation mechanism.  When set, the
+  component specification is ignored and all installed items are put in a
+  single "MONOLITHIC" package.  Some CPack generators do monolithic
+  packaging by default and may be asked to do component packaging by
+  setting ``CPACK_<GENNAME>_COMPONENT_INSTALL`` to ``TRUE``.
+
+.. variable:: CPACK_GENERATOR
+
+  List of CPack generators to use.  If not specified, CPack will create a
+  set of options following the naming pattern
+  :variable:`CPACK_BINARY_<GENNAME>` (e.g. ``CPACK_BINARY_NSIS``) allowing
+  the user to enable/disable individual generators.  If the ``-G`` option is
+  given on the :manual:`cpack <cpack(1)>` command line, it will override this
+  variable and any ``CPACK_BINARY_<GENNAME>`` options.
+
+.. variable:: CPACK_OUTPUT_CONFIG_FILE
+
+  The name of the CPack binary configuration file.  This file is the CPack
+  configuration generated by the CPack module for binary installers.
+  Defaults to ``CPackConfig.cmake``.
+
+.. variable:: CPACK_PACKAGE_EXECUTABLES
+
+  Lists each of the executables and associated text label to be used to
+  create Start Menu shortcuts.  For example, setting this to the list
+  ``ccmake;CMake`` will create a shortcut named "CMake" that will execute the
+  installed executable ``ccmake``.  Not all CPack generators use it (at least
+  NSIS, WIX and OSXX11 do).
+
+.. variable:: CPACK_STRIP_FILES
+
+  List of files to be stripped.  Starting with CMake 2.6.0,
+  ``CPACK_STRIP_FILES`` will be a boolean variable which enables
+  stripping of all files (a list of files evaluates to ``TRUE`` in CMake,
+  so this change is compatible).
+
+.. variable:: CPACK_VERBATIM_VARIABLES
+
+  If set to ``TRUE``, values of variables prefixed with ``CPACK_`` will be
+  escaped before being written to the configuration files, so that the cpack
+  program receives them exactly as they were specified.  If not, characters
+  like quotes and backslashes can cause parsing errors or alter the value
+  received by the cpack program.  Defaults to ``FALSE`` for backwards
+  compatibility.
+
+Variables for Source Package Generators
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following CPack variables are specific to source packages, and
+will not affect binary packages:
+
+.. variable:: CPACK_SOURCE_PACKAGE_FILE_NAME
+
+  The name of the source package.  For example ``cmake-2.6.1``.
+
+.. variable:: CPACK_SOURCE_STRIP_FILES
+
+  List of files in the source tree that will be stripped.  Starting with
+  CMake 2.6.0, ``CPACK_SOURCE_STRIP_FILES`` will be a boolean
+  variable which enables stripping of all files (a list of files evaluates
+  to ``TRUE`` in CMake, so this change is compatible).
+
+.. variable:: CPACK_SOURCE_GENERATOR
+
+  List of generators used for the source packages.  As with
+  :variable:`CPACK_GENERATOR`, if this is not specified then CPack will
+  create a set of options (e.g. ``CPACK_SOURCE_ZIP``) allowing
+  users to select which packages will be generated.
+
+.. variable:: CPACK_SOURCE_OUTPUT_CONFIG_FILE
+
+  The name of the CPack source configuration file.  This file is the CPack
+  configuration generated by the CPack module for source installers.
+  Defaults to ``CPackSourceConfig.cmake``.
+
+.. variable:: CPACK_SOURCE_IGNORE_FILES
+
+  Pattern of files in the source tree that won't be packaged when building
+  a source package.  This is a list of regular expression patterns (that
+  must be properly escaped), e.g.,
+  ``/CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*``
+
+Variables for Advanced Use
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following variables are for advanced uses of CPack:
+
+.. variable:: CPACK_CMAKE_GENERATOR
+
+  What CMake generator should be used if the project is a CMake
+  project.  Defaults to the value of :variable:`CMAKE_GENERATOR`.  Few users
+  will want to change this setting.
+
+.. variable:: CPACK_INSTALL_CMAKE_PROJECTS
+
+  List of four values that specify what project to install.  The four values
+  are: Build directory, Project Name, Project Component, Directory.  If
+  omitted, CPack will build an installer that installs everything.
+
+.. variable:: CPACK_SYSTEM_NAME
+
+  System name, defaults to the value of :variable:`CMAKE_SYSTEM_NAME`,
+  except on Windows where it will be ``win32`` or ``win64``.
+
+.. variable:: CPACK_PACKAGE_VERSION
+
+  Package full version, used internally.  By default, this is built from
+  :variable:`CPACK_PACKAGE_VERSION_MAJOR`,
+  :variable:`CPACK_PACKAGE_VERSION_MINOR`, and
+  :variable:`CPACK_PACKAGE_VERSION_PATCH`.
+
+.. variable:: CPACK_TOPLEVEL_TAG
+
+  Directory for the installed files.
+
+.. variable:: CPACK_INSTALL_COMMANDS
+
+  Extra commands to install components.
+
+.. variable:: CPACK_INSTALLED_DIRECTORIES
+
+  Extra directories to install.
+
+.. variable:: CPACK_PACKAGE_INSTALL_REGISTRY_KEY
+
+  Registry key used when installing this project.  This is only used by
+  installers for Windows.  The default value is based on the installation
+  directory.
+
+.. variable:: CPACK_CREATE_DESKTOP_LINKS
+
+  List of desktop links to create.  Each desktop link requires a
+  corresponding start menu shortcut as created by
+  :variable:`CPACK_PACKAGE_EXECUTABLES`.
+
+.. variable:: CPACK_BINARY_<GENNAME>
+
+  CPack generated options for binary generators.  The ``CPack.cmake`` module
+  generates (when :variable:`CPACK_GENERATOR` is not set) a set of CMake
+  options (see CMake :command:`option` command) which may then be used to
+  select the CPack generator(s) to be used when building the ``package``
+  target or when running :manual:`cpack <cpack(1)>` without the ``-G`` option.

-# --------------
-#
-# Build binary and source package installers
-#
-# Variables concerning CPack Components
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The CPackComponent module is the module which handles the component
-# part of CPack.  See CPack module for general information about CPack.
-#
-# For certain kinds of binary installers (including the graphical
-# installers on Mac OS X and Windows), CPack generates installers that
-# allow users to select individual application components to install.
-# The contents of each of the components are identified by the COMPONENT
-# argument of CMake's INSTALL command.  These components can be
-# annotated with user-friendly names and descriptions, inter-component
-# dependencies, etc., and grouped in various ways to customize the
-# resulting installer.  See the cpack_add_* commands, described below,
-# for more information about component-specific installations.
-#
-# Component-specific installation allows users to select specific sets
-# of components to install during the install process.  Installation
-# components are identified by the COMPONENT argument of CMake's INSTALL
-# commands, and should be further described by the following CPack
-# commands:
-#
-# .. variable:: CPACK_COMPONENTS_ALL
-#
-#  The list of component to install.
-#
-#  The default value of this variable is computed by CPack and contains all
-#  components defined by the project.  The user may set it to only include the
-#  specified components.
-#
-# .. variable:: CPACK_<GENNAME>_COMPONENT_INSTALL
-#
-#  Enable/Disable component install for CPack generator <GENNAME>.
-#
-#  Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy
-#  default behavior.  e.g.  RPM builds monolithic whereas NSIS builds
-#  component.  One can change the default behavior by setting this variable to
-#  0/1 or OFF/ON.
-#
-# .. variable:: CPACK_COMPONENTS_GROUPING
-#
-#  Specify how components are grouped for multi-package component-aware CPack
-#  generators.
-#
-#  Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates
-#  several packages files when asked for component packaging.  They group
-#  the component differently depending on the value of this variable:
-#
-#  * ONE_PER_GROUP (default): creates one package file per component group
-#  * ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
-#  * IGNORE : creates one package per component, i.e. IGNORE component group
-#
-#  One can specify different grouping for different CPack generator by
-#  using a CPACK_PROJECT_CONFIG_FILE.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_DISPLAY_NAME
-#
-#  The name to be displayed for a component.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_DESCRIPTION
-#
-#  The description of a component.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_GROUP
-#
-#  The group of a component.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_DEPENDS
-#
-#  The dependencies (list of components) on which this component depends.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_HIDDEN
-#
-#  True if this component is hidden from the user.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_REQUIRED
-#
-#  True if this component is required.
-#
-# .. variable:: CPACK_COMPONENT_<compName>_DISABLED
-#
-#  True if this component is not selected to be installed by default.
-#
-# .. command:: cpack_add_component
-#
-# Describes a CPack installation
-# component named by the COMPONENT argument to a CMake INSTALL command.

-#
-# DEPENDS lists the components on which this component depends.  If this
-# component is selected, then each of the components listed must also be
-# selected.  The dependency information is encoded within the installer
-# itself, so that users cannot install inconsistent sets of components.
-#
-# GROUP names the component group of which this component is a part.  If
-# not provided, the component will be a standalone component, not part
-# of any component group.  Component groups are described with the
-# cpack_add_component_group command, detailed below.
-#
-# INSTALL_TYPES lists the installation types of which this component is
-# a part.  When one of these installations types is selected, this

+
+For certain kinds of binary installers (including the graphical

+
+Component-specific installation allows users to select specific sets
+of components to install during the install process.  Installation
+components are identified by the COMPONENT argument of CMake's INSTALL
+commands, and should be further described by the following CPack
+commands:
+
+.. variable:: CPACK_COMPONENTS_ALL
+
+ The list of component to install.
+
+ The default value of this variable is computed by CPack and contains all
+ components defined by the project.  The user may set it to only include the
+ specified components.
+
+ Instead of specifying all the desired components, it is possible to obtain a
+ list of all defined components and then remove the unwanted ones from the
+ list. The :command:`get_cmake_property` command can be used to obtain the
+ ``COMPONENTS`` property, then the :command:`list(REMOVE_ITEM)` command can be
+ used to remove the unwanted ones. For example, to use all defined components
+ except ``foo`` and ``bar``::
+
+   get_cmake_property(CPACK_COMPONENTS_ALL COMPONENTS)
+   list(REMOVE_ITEM CPACK_COMPONENTS_ALL "foo" "bar")
+
+.. variable:: CPACK_<GENNAME>_COMPONENT_INSTALL
+
+ Enable/Disable component install for CPack generator <GENNAME>.
+
+ Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy
+ default behavior.  e.g.  RPM builds monolithic whereas NSIS builds
+ component.  One can change the default behavior by setting this variable to

+only those components explicitly marked as DOWNLOADED or that have a
+specified ARCHIVE_FILE will be downloaded.  Additionally, the ALL
+option implies ADD_REMOVE (unless NO_ADD_REMOVE is specified).
+
+ADD_REMOVE indicates that CPack should install a copy of the installer
+that can be called from Windows' Add/Remove Programs dialog (via the
+"Modify" button) to change the set of installed components.
+NO_ADD_REMOVE turns off this behavior.  This option is ignored on Mac
+OS X.

-# --------
-#
-# .. _QtIFW: http://doc.qt.io/qtinstallerframework/index.html
-#
-# This module looks for the location of the command line utilities supplied
-# with the Qt Installer Framework (QtIFW_).
-#
-# The module also defines several commands to control the behavior of the
-# CPack ``IFW`` generator.
-#
-#
-# Overview
-# ^^^^^^^^
-#
-# CPack ``IFW`` generator helps you to create online and offline
-# binary cross-platform installers with a graphical user interface.
-#
-# CPack IFW generator prepares project installation and generates configuration
-# and meta information for QtIFW_ tools.
-#
-# The QtIFW_ provides a set of tools and utilities to create
-# installers for the supported desktop Qt platforms: Linux, Microsoft Windows,
-# and Mac OS X.
-#
-# You should also install QtIFW_ to use CPack ``IFW`` generator.
-#
-# Hints
-# ^^^^^
-#
-# Generally, the CPack ``IFW`` generator automatically finds QtIFW_ tools,
-# but if you don't use a default path for installation of the QtIFW_ tools,
-# the path may be specified in either a CMake or an environment variable:
-#
-# .. variable:: CPACK_IFW_ROOT
-#
-#  An CMake variable which specifies the location of the QtIFW_ tool suite.
-#
-#  The variable will be cached in the ``CPackConfig.cmake`` file and used at
-#  CPack runtime.
-#
-# .. variable:: QTIFWDIR
-#
-#  An environment variable which specifies the location of the QtIFW_ tool
-#  suite.
-#
-# .. note::
-#   The specified path should not contain "bin" at the end
-#   (for example: "D:\\DevTools\\QtIFW2.0.5").
-#
-# The :variable:`CPACK_IFW_ROOT` variable has a higher priority and overrides
-# the value of the :variable:`QTIFWDIR` variable.
-#
-# Internationalization
-# ^^^^^^^^^^^^^^^^^^^^
-#
-# Some variables and command arguments support internationalization via
-# CMake script. This is an optional feature.
-#
-# Installers created by QtIFW_ tools have built-in support for
-# internationalization and many phrases are localized to many languages,
-# but this does not apply to the description of the your components and groups
-# that will be distributed.
-#
-# Localization of the description of your components and groups is useful for
-# users of your installers.
-#
-# A localized variable or argument can contain a single default value, and a
-# set of pairs the name of the locale and the localized value.
-#
-# For example:
-#
-# .. code-block:: cmake
-#
-#    set(LOCALIZABLE_VARIABLE "Default value"
-#      en "English value"
-#      en_US "American value"
-#      en_GB "Great Britain value"
-#      )
-#
-# Variables

-# generator.

+CPackIFW
+--------
+
+The documentation for the CPack IFW generator has moved here: :cpack_gen:`CPack IFW Generator`
+
+.. _QtIFW: http://doc.qt.io/qtinstallerframework/index.html
+
+This module looks for the location of the command line utilities supplied
+with the Qt Installer Framework (QtIFW_).
+
+The module also defines several commands to control the behavior of the
+CPack ``IFW`` generator.
+
+Commands
+^^^^^^^^
+
+The module defines the following commands:
+
+.. command:: cpack_ifw_configure_component
+
+  Sets the arguments specific to the CPack IFW generator.
+
+  ::
+
+    cpack_ifw_configure_component(<compname> [COMMON] [ESSENTIAL] [VIRTUAL]
+                        [FORCED_INSTALLATION] [REQUIRES_ADMIN_RIGHTS]
+                        [NAME <name>]
+                        [DISPLAY_NAME <display_name>] # Note: Internationalization supported
+                        [DESCRIPTION <description>] # Note: Internationalization supported
+                        [UPDATE_TEXT <update_text>]
+                        [VERSION <version>]
+                        [RELEASE_DATE <release_date>]
+                        [SCRIPT <script>]
+                        [PRIORITY|SORTING_PRIORITY <sorting_priority>] # Note: PRIORITY is deprecated
+                        [DEPENDS|DEPENDENCIES <com_id> ...]
+                        [AUTO_DEPEND_ON <comp_id> ...]
+                        [LICENSES <display_name> <file_path> ...]
+                        [DEFAULT <value>]
+                        [USER_INTERFACES <file_path> <file_path> ...]
+                        [TRANSLATIONS <file_path> <file_path> ...]
+                        [REPLACES <comp_id> ...]
+                        [CHECKABLE <value>])
+
+  This command should be called after :command:`cpack_add_component` command.
+
+  ``COMMON``
+    if set, then the component will be packaged and installed as part
+    of a group to which it belongs.
+
+  ``ESSENTIAL``
+    if set, then the package manager stays disabled until that
+    component is updated.
+
+  ``VIRTUAL``
+    if set, then the component will be hidden from the installer.
+    It is a equivalent of the ``HIDDEN`` option from the
+    :command:`cpack_add_component` command.
+
+  ``FORCED_INSTALLATION``
+    if set, then the component must always be installed.
+    It is a equivalent of the ``REQUARED`` option from the
+    :command:`cpack_add_component` command.
+
+  ``REQUIRES_ADMIN_RIGHTS``
+    set it if the component needs to be installed with elevated permissions.
+
+  ``NAME``
+    is used to create domain-like identification for this component.
+    By default used origin component name.
+
+  ``DISPLAY_NAME``
+    set to rewrite original name configured by
+    :command:`cpack_add_component` command.
+
+  ``DESCRIPTION``
+    set to rewrite original description configured by
+    :command:`cpack_add_component` command.
+
+  ``UPDATE_TEXT``
+    will be added to the component description if this is an update to
+    the component.
+
+  ``VERSION``
+    is version of component.
+    By default used :variable:`CPACK_PACKAGE_VERSION`.
+
+  ``RELEASE_DATE``
+    keep empty to auto generate.
+
+  ``SCRIPT``
+    is a relative or absolute path to operations script
+    for this component.
+
+  ``PRIORITY`` | ``SORTING_PRIORITY``
+    is priority of the component in the tree.
+    The ``PRIORITY`` option is deprecated and will be removed in a future
+    version of CMake. Please use ``SORTING_PRIORITY`` option instead.
+
+  ``DEPENDS`` | ``DEPENDENCIES``
+    list of dependency component or component group identifiers in
+    QtIFW_ style.
+
+  ``AUTO_DEPEND_ON``
+    list of identifiers of component or component group in QtIFW_ style
+    that this component has an automatic dependency on.
+
+  ``LICENSES``
+    pair of <display_name> and <file_path> of license text for this
+    component. You can specify more then one license.
+
+  ``DEFAULT``
+    Possible values are: TRUE, FALSE, and SCRIPT.
+    Set to FALSE to disable the component in the installer or to SCRIPT
+    to resolved during runtime (don't forget add the file of the script
+    as a value of the ``SCRIPT`` option).
+
+  ``USER_INTERFACES``
+    is a list of <file_path> ('.ui' files) representing pages to load.
+
+  ``TRANSLATIONS``
+    is a list of <file_path> ('.qm' files) representing translations to load.
+
+  ``REPLACES``
+    list of identifiers of component or component group to replace.
+
+  ``CHECKABLE``
+    Possible values are: TRUE, FALSE.
+    Set to FALSE if you want to hide the checkbox for an item.
+    This is useful when only a few subcomponents should be selected
+    instead of all.
+
+
+.. command:: cpack_ifw_configure_component_group
+
+  Sets the arguments specific to the CPack IFW generator.
+
+  ::
+
+    cpack_ifw_configure_component_group(<groupname> [VIRTUAL]
+                        [FORCED_INSTALLATION] [REQUIRES_ADMIN_RIGHTS]
+                        [NAME <name>]
+                        [DISPLAY_NAME <display_name>] # Note: Internationalization supported
+                        [DESCRIPTION <description>] # Note: Internationalization supported

+                        [VERSION <version>]
+                        [RELEASE_DATE <release_date>]
+                        [SCRIPT <script>]
+                        [PRIORITY|SORTING_PRIORITY <sorting_priority>] # Note: PRIORITY is deprecated
+                        [DEPENDS|DEPENDENCIES <com_id> ...]
+                        [AUTO_DEPEND_ON <comp_id> ...]
+                        [LICENSES <display_name> <file_path> ...]
+                        [DEFAULT <value>]

+                        [REPLACES <comp_id> ...]
+                        [CHECKABLE <value>])
+
+  This command should be called after :command:`cpack_add_component_group`
+  command.
+
+  ``VIRTUAL``
+    if set, then the group will be hidden from the installer.
+    Note that setting this on a root component does not work.
+
+  ``FORCED_INSTALLATION``
+    if set, then the group must always be installed.
+
+  ``REQUIRES_ADMIN_RIGHTS``
+    set it if the component group needs to be installed with elevated
+    permissions.
+
+  ``NAME``
+    is used to create domain-like identification for this component group.
+    By default used origin component group name.
+
+  ``DISPLAY_NAME``
+    set to rewrite original name configured by
+    :command:`cpack_add_component_group` command.
+
+  ``DESCRIPTION``
+    set to rewrite original description configured by
+    :command:`cpack_add_component_group` command.
+
+  ``UPDATE_TEXT``
+    will be added to the component group description if this is an update to
+    the component group.
+
+  ``VERSION``
+    is version of component group.
+    By default used :variable:`CPACK_PACKAGE_VERSION`.
+
+  ``RELEASE_DATE``
+    keep empty to auto generate.
+
+  ``SCRIPT``
+    is a relative or absolute path to operations script
+    for this component group.
+
+  ``PRIORITY`` | ``SORTING_PRIORITY``
+    is priority of the component group in the tree.
+    The ``PRIORITY`` option is deprecated and will be removed in a future
+    version of CMake. Please use ``SORTING_PRIORITY`` option instead.
+
+  ``DEPENDS`` | ``DEPENDENCIES``
+    list of dependency component or component group identifiers in
+    QtIFW_ style.
+
+  ``AUTO_DEPEND_ON``
+    list of identifiers of component or component group in QtIFW_ style
+    that this component group has an automatic dependency on.
+
+  ``LICENSES``
+    pair of <display_name> and <file_path> of license text for this
+    component group. You can specify more then one license.
+
+  ``DEFAULT``
+    Possible values are: TRUE, FALSE, and SCRIPT.
+    Set to TRUE to preselect the group in the installer
+    (this takes effect only on groups that have no visible child components)
+    or to SCRIPT to resolved during runtime (don't forget add the file of
+    the script as a value of the ``SCRIPT`` option).
+
+  ``USER_INTERFACES``
+    is a list of <file_path> ('.ui' files) representing pages to load.

+
+This command temporarily sets the ``CMAKE_REQUIRED_DEFINITIONS`` variable

+A positive result from this check indicates only that the compiler did not

+effect or even a specific one is beyond the scope of this module.
+
+.. note::
+  Since the :command:`try_compile` command forwards flags from variables
+  like :variable:`CMAKE_C_FLAGS <CMAKE_<LANG>_FLAGS>`, unknown flags

+    A :ref:`;-list <CMake Language Lists>` of compiler definitions of the form
+    ``-DFOO`` or ``-DFOO=bar``. A definition for the name specified by
+    ``<resultVar>`` will also be added automatically.
+
+  ``CMAKE_REQUIRED_INCLUDES``
+    A :ref:`;-list <CMake Language Lists>` of header search paths to pass to
+    the compiler. These will be the only header search paths used by
+    ``try_compile()``, i.e. the contents of the :prop_dir:`INCLUDE_DIRECTORIES`
+    directory property will be ignored.
+
+  ``CMAKE_REQUIRED_LINK_OPTIONS``
+    A :ref:`;-list <CMake Language Lists>` of options to add to the link

+
+  ``CMAKE_REQUIRED_LIBRARIES``

+    :ref:`Imported Targets <Imported Targets>` (see :command:`try_compile` for
+    further details).
+
+  ``CMAKE_REQUIRED_QUIET``
+    If this variable evaluates to a boolean true value, all status messages
+    associated with the check will be suppressed.
+
+  The check is only performed once, with the result cached in the variable
+  named by ``<resultVar>``. Every subsequent CMake run will re-use this cached
+  value rather than performing the check again, even if the ``<code>`` changes.
+  In order to force the check to be re-evaluated, the variable named by

+
+    check_c_source_runs(<code> <resultVar>)
+
+  Check that the source supplied in ``<code>`` can be compiled as a C source
+  file, linked as an executable and then run. The ``<code>`` must contain at
+  least a ``main()`` function. If the ``<code>`` could be built and run
+  successfully, the internal cache variable specified by ``<resultVar>`` will
+  be set to 1, otherwise it will be set to an value that evaluates to boolean
+  false (e.g. an empty string or an error message).
+
+  The underlying check is performed by the :command:`try_run` command. The
+  compile and link commands can be influenced by setting any of the following
+  variables prior to calling ``check_c_source_runs()``:
+
+  ``CMAKE_REQUIRED_FLAGS``
+    Additional flags to pass to the compiler. Note that the contents of
+    :variable:`CMAKE_C_FLAGS <CMAKE_<LANG>_FLAGS>` and its associated
+    configuration-specific variable are automatically added to the compiler
+    command before the contents of ``CMAKE_REQUIRED_FLAGS``.
+
+  ``CMAKE_REQUIRED_DEFINITIONS``
+    A :ref:`;-list <CMake Language Lists>` of compiler definitions of the form
+    ``-DFOO`` or ``-DFOO=bar``. A definition for the name specified by
+    ``<resultVar>`` will also be added automatically.
+
+  ``CMAKE_REQUIRED_INCLUDES``
+    A :ref:`;-list <CMake Language Lists>` of header search paths to pass to
+    the compiler. These will be the only header search paths used by
+    ``try_run()``, i.e. the contents of the :prop_dir:`INCLUDE_DIRECTORIES`
+    directory property will be ignored.

+    further details).
+
+  ``CMAKE_REQUIRED_QUIET``
+    If this variable evaluates to a boolean true value, all status messages
+    associated with the check will be suppressed.
+
+  The check is only performed once, with the result cached in the variable
+  named by ``<resultVar>``. Every subsequent CMake run will re-use this cached
+  value rather than performing the check again, even if the ``<code>`` changes.
+  In order to force the check to be re-evaluated, the variable named by
+  ``<resultVar>`` must be manually removed from the cache.

+Check whether the CXX compiler supports a given flag.
+
+.. command:: check_cxx_compiler_flag
+
+  .. code-block:: cmake
+
+    check_cxx_compiler_flag(<flag> <var>)
+
+  Check that the ``<flag>`` is accepted by the compiler without
+  a diagnostic.  Stores the result in an internal cache entry
+  named ``<var>``.
+
+This command temporarily sets the ``CMAKE_REQUIRED_DEFINITIONS`` variable
+and calls the ``check_cxx_source_compiles`` macro from the
+:module:`CheckCXXSourceCompiles` module.  See documentation of that
+module for a listing of variables that can otherwise modify the build.
+
+A positive result from this check indicates only that the compiler did not
+issue a diagnostic message when given the flag.  Whether the flag has any
+effect or even a specific one is beyond the scope of this module.
+
+.. note::
+  Since the :command:`try_compile` command forwards flags from variables
+  like :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>`, unknown flags
+  in such variables may cause a false negative for this check.

+
+.. command:: check_fortran_compiler_flag
+
+  .. code-block:: cmake
+
+    check_fortran_compiler_flag(<flag> <var>)
+
+  Check that the ``<flag>`` is accepted by the compiler without
+  a diagnostic.  Stores the result in an internal cache entry
+  named ``<var>``.
+
+This command temporarily sets the ``CMAKE_REQUIRED_DEFINITIONS`` variable
+and calls the ``check_fortran_source_compiles`` macro from the
+:module:`CheckFortranSourceCompiles` module.  See documentation of that
+module for a listing of variables that can otherwise modify the build.
+
+A positive result from this check indicates only that the compiler did not
+issue a diagnostic message when given the flag.  Whether the flag has any
+effect or even a specific one is beyond the scope of this module.
+
+.. note::
+  Since the :command:`try_compile` command forwards flags from variables
+  like :variable:`CMAKE_Fortran_FLAGS <CMAKE_<LANG>_FLAGS>`, unknown flags
+  in such variables may cause a false negative for this check.

+Check if given Fortran source compiles and links into an executable.
+
+.. command:: check_fortran_source_compiles
+
+  .. code-block:: cmake
+
+    check_fortran_source_compiles(<code> <resultVar>
+        [FAIL_REGEX <regex>...]
+        [SRC_EXT <extension>]
+    )
+
+  Checks that the source supplied in ``<code>`` can be compiled as a Fortran
+  source file and linked as an executable. The ``<code>`` must be a Fortran program
+  containing at least an ``end`` statement--for example:
+
+  .. code-block:: cmake
+
+    check_fortran_source_compiles("character :: b; error stop b; end" F2018ESTOPOK SRC_EXT F90)
+
+  This command can help avoid costly build processes when a compiler lacks support
+  for a necessary feature, or a particular vendor library is not compatible with
+  the Fortran compiler version being used. This generate-time check may advise the
+  user of such before the main build process. See also the
+  :command:`check_fortran_source_runs` command to actually run the compiled code.
+
+  The result will be stored in the internal cache
+  variable ``<resultVar>``, with a boolean true value for success and boolean
+  false for failure.
+
+  If ``FAIL_REGEX`` is provided, then failure is determined by checking
+  if anything in the output matches any of the specified regular expressions.
+
+  By default, the test source file will be given a ``.F`` file extension. The
+  ``SRC_EXT`` option can be used to override this with ``.<extension>`` instead--
+  ``.F90`` is a typical choice.
+
+  The underlying check is performed by the :command:`try_compile` command. The
+  compile and link commands can be influenced by setting any of the following
+  variables prior to calling ``check_fortran_source_compiles()``:
+
+  ``CMAKE_REQUIRED_FLAGS``
+    Additional flags to pass to the compiler. Note that the contents of
+    :variable:`CMAKE_Fortran_FLAGS <CMAKE_<LANG>_FLAGS>` and its associated
+    configuration-specific variable are automatically added to the compiler
+    command before the contents of ``CMAKE_REQUIRED_FLAGS``.
+
+  ``CMAKE_REQUIRED_DEFINITIONS``
+    A :ref:`;-list <CMake Language Lists>` of compiler definitions of the form
+    ``-DFOO`` or ``-DFOO=bar``. A definition for the name specified by
+    ``<resultVar>`` will also be added automatically.
+
+  ``CMAKE_REQUIRED_INCLUDES``
+    A :ref:`;-list <CMake Language Lists>` of header search paths to pass to
+    the compiler. These will be the only header search paths used by
+    ``try_compile()``, i.e. the contents of the :prop_dir:`INCLUDE_DIRECTORIES`
+    directory property will be ignored.
+
+  ``CMAKE_REQUIRED_LINK_OPTIONS``
+    A :ref:`;-list <CMake Language Lists>` of options to add to the link
+    command (see :command:`try_compile` for further details).
+
+  ``CMAKE_REQUIRED_LIBRARIES``
+    A :ref:`;-list <CMake Language Lists>` of libraries to add to the link
+    command. These can be the name of system libraries or they can be
+    :ref:`Imported Targets <Imported Targets>` (see :command:`try_compile` for
+    further details).
+
+  ``CMAKE_REQUIRED_QUIET``
+    If this variable evaluates to a boolean true value, all status messages
+    associated with the check will be suppressed.
+
+  The check is only performed once, with the result cached in the variable
+  named by ``<resultVar>``. Every subsequent CMake run will re-use this cached
+  value rather than performing the check again, even if the ``<code>`` changes.
+  In order to force the check to be re-evaluated, the variable named by
+  ``<resultVar>`` must be manually removed from the cache.

+External Project Definition
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 .. command:: ExternalProject_Add
 
-  The ``ExternalProject_Add`` function creates a custom target to drive
+  The ``ExternalProject_Add()`` function creates a custom target to drive
   download, update/patch, configure, build, install and test steps of an
-  external project::
-
-   ExternalProject_Add(<name> [<option>...])
-
-  General options are:
-
-  ``DEPENDS <projects>...``
-    Targets on which the project depends
-  ``PREFIX <dir>``
-    Root dir for entire project
-  ``LIST_SEPARATOR <sep>``
-    Sep to be replaced by ; in cmd lines
-  ``TMP_DIR <dir>``
-    Directory to store temporary files
-  ``STAMP_DIR <dir>``
-    Directory to store step timestamps
-  ``EXCLUDE_FROM_ALL 1``
-    The "all" target does not depend on this
-
-  Download step options are:
-
-  ``DOWNLOAD_NAME <fname>``
-    File name to store (if not end of URL)
-  ``DOWNLOAD_DIR <dir>``
-    Directory to store downloaded files
-  ``DOWNLOAD_COMMAND <cmd>...``
-    Command to download source tree
-  ``DOWNLOAD_NO_PROGRESS 1``
-    Disable download progress reports
-  ``CVS_REPOSITORY <cvsroot>``
-    CVSROOT of CVS repository
-  ``CVS_MODULE <mod>``
-    Module to checkout from CVS repo
-  ``CVS_TAG <tag>``
-    Tag to checkout from CVS repo
-  ``SVN_REPOSITORY <url>``
-    URL of Subversion repo
-  ``SVN_REVISION -r<rev>``
-    Revision to checkout from Subversion repo
-  ``SVN_USERNAME <username>``
-    Username for Subversion checkout and update
-  ``SVN_PASSWORD <password>``
-    Password for Subversion checkout and update
-  ``SVN_TRUST_CERT 1``
-    Trust the Subversion server site certificate
-  ``GIT_REPOSITORY <url>``
-    URL of git repo
-  ``GIT_TAG <tag>``
-    Git branch name, commit id or tag
-  ``GIT_REMOTE_NAME <name>``
-    The optional name of the remote, default to ``origin``
-  ``GIT_SUBMODULES <module>...``
-    Git submodules that shall be updated, all if empty
-  ``GIT_SHALLOW 1``
-    Tell Git to clone with ``--depth 1``.  Use when ``GIT_TAG`` is not
-    specified or when it names a branch in order to download only the
-    tip of the branch without the rest of its history.
-  ``GIT_PROGRESS 1``
-    Tell Git to clone with ``--progress``.  For large projects, the clone step
-    does not output anything which can make the build appear to have stalled.
-    This option forces Git to output progress information during the clone step
-    so that forward progress is indicated.
-  ``GIT_CONFIG <option>...``
-    Tell Git to clone with ``--config <option>``.  Use additional configuration
-    parameters when cloning the project (``key=value`` as expected by ``git
-    config``).
-  ``HG_REPOSITORY <url>``
-    URL of mercurial repo
-  ``HG_TAG <tag>``
-    Mercurial branch name, commit id or tag
-  ``URL /.../src.tgz [/.../src.tgz]...``
-    Full path or URL(s) of source.  Multiple URLs are allowed as mirrors.
-  ``URL_HASH ALGO=value``
-    Hash of file at URL
-  ``URL_MD5 md5``
-    Equivalent to URL_HASH MD5=md5
-  ``HTTP_USERNAME <username>``
-    Username for download operation
-  ``HTTP_PASSWORD <username>``
-    Password for download operation
-  ``HTTP_HEADER <header>``
-    HTTP header for download operation. Suboption can be repeated several times.
-  ``TLS_VERIFY <bool>``
-    Should certificate for https be checked
-  ``TLS_CAINFO <file>``
-    Path to a certificate authority file
-  ``TIMEOUT <seconds>``
-    Time allowed for file download operations
-  ``DOWNLOAD_NO_EXTRACT 1``
-    Just download the file and do not extract it; the full path to the
-    downloaded file is available as ``<DOWNLOADED_FILE>``.
-
-  Update/Patch step options are:
-
-  ``UPDATE_COMMAND <cmd>...``
-    Source work-tree update command
-  ``UPDATE_DISCONNECTED 1``
-    Never update automatically from the remote repository
-  ``PATCH_COMMAND <cmd>...``
-    Command to patch downloaded source
-
-  Configure step options are:
-
-  ``SOURCE_DIR <dir>``
-    Source dir to be used for build
-  ``SOURCE_SUBDIR <dir>``
-    Path to source CMakeLists.txt relative to ``SOURCE_DIR``
-  ``CONFIGURE_COMMAND <cmd>...``
-    Build tree configuration command
-  ``CMAKE_COMMAND /.../cmake``
-    Specify alternative cmake executable
-  ``CMAKE_GENERATOR <gen>``
-    Specify generator for native build
-  ``CMAKE_GENERATOR_PLATFORM <platform>``
-    Generator-specific platform name
-  ``CMAKE_GENERATOR_TOOLSET <toolset>``
-    Generator-specific toolset name
-  ``CMAKE_ARGS <arg>...``
-    Arguments to CMake command line.
-    These arguments are passed to CMake command line, and can contain
-    arguments other than cache values, see also
-    :manual:`CMake Options <cmake(1)>`. Arguments in the form
-    ``-Dvar:string=on`` are always passed to the command line, and
-    therefore cannot be changed by the user.
-    Arguments may use
-    :manual:`generator expressions <cmake-generator-expressions(7)>`.
-  ``CMAKE_CACHE_ARGS <arg>...``
-    Initial cache arguments, of the form ``-Dvar:string=on``.
-    These arguments are written in a pre-load a script that populates
-    CMake cache, see also :manual:`cmake -C <cmake(1)>`. This allows one to
-    overcome command line length limits.
-    These arguments are :command:`set` using the ``FORCE`` argument,
-    and therefore cannot be changed by the user.
-    Arguments may use
-    :manual:`generator expressions <cmake-generator-expressions(7)>`.
-  ``CMAKE_CACHE_DEFAULT_ARGS <arg>...``
-    Initial default cache arguments, of the form ``-Dvar:string=on``.
-    These arguments are written in a pre-load a script that populates
-    CMake cache, see also :manual:`cmake -C <cmake(1)>`. This allows one to
-    overcome command line length limits.
-    These arguments can be used as default value that will be set if no
-    previous value is found in the cache, and that the user can change
-    later.
-    Arguments may use
-    :manual:`generator expressions <cmake-generator-expressions(7)>`.
-
-  Build step options are:
-
-  ``BINARY_DIR <dir>``
-    Specify build dir location
-  ``BUILD_COMMAND <cmd>...``
-    Command to drive the native build
-  ``BUILD_IN_SOURCE 1``
-    Use source dir for build dir
-  ``BUILD_ALWAYS 1``
-    No stamp file, build step always runs
-  ``BUILD_BYPRODUCTS <file>...``
-    Files that will be generated by the build command but may or may
-    not have their modification time updated by subsequent builds.
-
-  Install step options are:
-
-  ``INSTALL_DIR <dir>``
-    Installation prefix to be placed in the ``<INSTALL_DIR>`` placeholder.
-    This does not actually configure the external project to install to
-    the given prefix.  That must be done by passing appropriate arguments
-    to the external project configuration step, e.g. using ``<INSTALL_DIR>``.
-  ``INSTALL_COMMAND <cmd>...``
-    Command to drive installation of the external project after it has been
-    built.  This only happens at the *build* time of the calling project.
-    In order to install files from the external project alongside the
-    locally-built files, a separate local :command:`install` call must be
-    added to pick the files up from one of the external project trees.
-
-  Test step options are:
-
-  ``TEST_BEFORE_INSTALL 1``
-    Add test step executed before install step
-  ``TEST_AFTER_INSTALL 1``
-    Add test step executed after install step
-  ``TEST_EXCLUDE_FROM_MAIN 1``
-    Main target does not depend on the test step
-  ``TEST_COMMAND <cmd>...``
-    Command to drive test
-
-  Output logging options are:
-
-  ``LOG_DOWNLOAD 1``
-    Wrap download in script to log output
-  ``LOG_UPDATE 1``
-    Wrap update in script to log output
-  ``LOG_CONFIGURE 1``
-    Wrap configure in script to log output
-  ``LOG_BUILD 1``
-    Wrap build in script to log output
-  ``LOG_TEST 1``
-    Wrap test in script to log output
-  ``LOG_INSTALL 1``
-    Wrap install in script to log output
-
-  Steps can be given direct access to the terminal if possible.  With
-  the :generator:`Ninja` generator, this places the steps in the
-  ``console`` :prop_gbl:`pool <JOB_POOLS>`.  Options are:
-
-  ``USES_TERMINAL_DOWNLOAD 1``
-    Give download terminal access.
-  ``USES_TERMINAL_UPDATE 1``
-    Give update terminal access.
-  ``USES_TERMINAL_CONFIGURE 1``
-    Give configure terminal access.
-  ``USES_TERMINAL_BUILD 1``
-    Give build terminal access.
-  ``USES_TERMINAL_TEST 1``
-    Give test terminal access.
-  ``USES_TERMINAL_INSTALL 1``
-    Give install terminal access.
-
-  Other options are:
-
-  ``STEP_TARGETS <step-target>...``
-    Generate custom targets for these steps
-  ``INDEPENDENT_STEP_TARGETS <step-target>...``
-    Generate custom targets for these steps that do not depend on other
-    external projects even if a dependency is set
-
-  The ``*_DIR`` options specify directories for the project, with default
-  directories computed as follows.  If the ``PREFIX`` option is given to
-  ``ExternalProject_Add()`` or the ``EP_PREFIX`` directory property is set,
-  then an external project is built and installed under the specified prefix::
-
-   TMP_DIR      = <prefix>/tmp
-   STAMP_DIR    = <prefix>/src/<name>-stamp
-   DOWNLOAD_DIR = <prefix>/src
-   SOURCE_DIR   = <prefix>/src/<name>
-   BINARY_DIR   = <prefix>/src/<name>-build
-   INSTALL_DIR  = <prefix>
-
-  Otherwise, if the ``EP_BASE`` directory property is set then components
-  of an external project are stored under the specified base::
-
-   TMP_DIR      = <base>/tmp/<name>
-   STAMP_DIR    = <base>/Stamp/<name>
-   DOWNLOAD_DIR = <base>/Download/<name>
-   SOURCE_DIR   = <base>/Source/<name>
-   BINARY_DIR   = <base>/Build/<name>
-   INSTALL_DIR  = <base>/Install/<name>
-
-  If no ``PREFIX``, ``EP_PREFIX``, or ``EP_BASE`` is specified then the
-  default is to set ``PREFIX`` to ``<name>-prefix``.  Relative paths are
-  interpreted with respect to the build directory corresponding to the
-  source directory in which ``ExternalProject_Add`` is invoked.
-
-  If ``SOURCE_SUBDIR`` is set and no ``CONFIGURE_COMMAND`` is specified, the
-  configure command will run CMake using the ``CMakeLists.txt`` located in the
-  relative path specified by ``SOURCE_SUBDIR``, relative to the ``SOURCE_DIR``.
-  If no ``SOURCE_SUBDIR`` is given, ``SOURCE_DIR`` is used.
-
-  If ``SOURCE_DIR`` is explicitly set to an existing directory the project
-  will be built from it.  Otherwise a download step must be specified
-  using one of the ``DOWNLOAD_COMMAND``, ``CVS_*``, ``SVN_*``, or ``URL``
-  options.  The ``URL`` option may refer locally to a directory or source
-  tarball, or refer to a remote tarball (e.g. ``http://.../src.tgz``).
-
-  If ``UPDATE_DISCONNECTED`` is set, the update step is not executed
-  automatically when building the main target. The update step can still
-  be added as a step target and called manually. This is useful if you
-  want to allow one to build the project when you are disconnected from the
-  network (you might still need the network for the download step).
-  This is disabled by default.
-  The directory property ``EP_UPDATE_DISCONNECTED`` can be used to change
-  the default value for all the external projects in the current
-  directory and its subdirectories.
+  external project:
+
+  .. code-block:: cmake
+
+    ExternalProject_Add(<name> [<option>...])
+
+  The individual steps within the process can be driven independently if
+  required (e.g. for CDash submission) and extra custom steps can be defined,
+  along with the ability to control the step dependencies. The directory
+  structure used for the management of the external project can also be
+  customized. The function supports a large number of options which can be used
+  to tailor the external project behavior.
+
+  **Directory Options:**
+    Most of the time, the default directory layout is sufficient. It is largely
+    an implementation detail that the main project usually doesn't need to
+    change. In some circumstances, however, control over the directory layout
+    can be useful or necessary. The directory options are potentially more
+    useful from the point of view that the main build can use the
+    :command:`ExternalProject_Get_Property` command to retrieve their values,
+    thereby allowing the main project to refer to build artifacts of the
+    external project.
+
+    ``PREFIX <dir>``
+      Root directory for the external project. Unless otherwise noted below,
+      all other directories associated with the external project will be
+      created under here.
+
+    ``TMP_DIR <dir>``
+      Directory in which to store temporary files.
+
+    ``STAMP_DIR <dir>``
+      Directory in which to store the timestamps of each step. Log files from
+      individual steps are also created in here unless overriden by LOG_DIR
+      (see *Logging Options* below).
+
+    ``LOG_DIR <dir>``
+      Directory in which to store the logs of each step.
+
+    ``DOWNLOAD_DIR <dir>``
+      Directory in which to store downloaded files before unpacking them. This
+      directory is only used by the URL download method, all other download
+      methods use ``SOURCE_DIR`` directly instead.
+
+    ``SOURCE_DIR <dir>``
+      Source directory into which downloaded contents will be unpacked, or for
+      non-URL download methods, the directory in which the repository should be
+      checked out, cloned, etc. If no download method is specified, this must
+      point to an existing directory where the external project has already
+      been unpacked or cloned/checked out.
+
+      .. note::
+         If a download method is specified, any existing contents of the source
+         directory may be deleted. Only the URL download method checks whether
+         this directory is either missing or empty before initiating the
+         download, stopping with an error if it is not empty. All other
+         download methods silently discard any previous contents of the source
+         directory.
+
+    ``BINARY_DIR <dir>``
+      Specify the build directory location. This option is ignored if
+      ``BUILD_IN_SOURCE`` is enabled.
+
+    ``INSTALL_DIR <dir>``
+      Installation prefix to be placed in the ``<INSTALL_DIR>`` placeholder.
+      This does not actually configure the external project to install to
+      the given prefix. That must be done by passing appropriate arguments
+      to the external project configuration step, e.g. using ``<INSTALL_DIR>``.
+
+    If any of the above ``..._DIR`` options are not specified, their defaults
+    are computed as follows. If the ``PREFIX`` option is given or the
+    ``EP_PREFIX`` directory property is set, then an external project is built
+    and installed under the specified prefix::
+
+      TMP_DIR      = <prefix>/tmp
+      STAMP_DIR    = <prefix>/src/<name>-stamp
+      DOWNLOAD_DIR = <prefix>/src
+      SOURCE_DIR   = <prefix>/src/<name>
+      BINARY_DIR   = <prefix>/src/<name>-build
+      INSTALL_DIR  = <prefix>
+      LOG_DIR      = <STAMP_DIR>
+
+    Otherwise, if the ``EP_BASE`` directory property is set then components
+    of an external project are stored under the specified base::
+
+      TMP_DIR      = <base>/tmp/<name>
+      STAMP_DIR    = <base>/Stamp/<name>
+      DOWNLOAD_DIR = <base>/Download/<name>
+      SOURCE_DIR   = <base>/Source/<name>
+      BINARY_DIR   = <base>/Build/<name>
+      INSTALL_DIR  = <base>/Install/<name>
+      LOG_DIR      = <STAMP_DIR>
+
+    If no ``PREFIX``, ``EP_PREFIX``, or ``EP_BASE`` is specified, then the
+    default is to set ``PREFIX`` to ``<name>-prefix``. Relative paths are
+    interpreted with respect to :variable:`CMAKE_CURRENT_BINARY_DIR` at the
+    point where ``ExternalProject_Add()`` is called.
+
+  **Download Step Options:**
+    A download method can be omitted if the ``SOURCE_DIR`` option is used to
+    point to an existing non-empty directory. Otherwise, one of the download
+    methods below must be specified (multiple download methods should not be
+    given) or a custom ``DOWNLOAD_COMMAND`` provided.
+
+    ``DOWNLOAD_COMMAND <cmd>...``
+      Overrides the command used for the download step
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). If this option is specified, all other download options will
+      be ignored. Providing an empty string for ``<cmd>`` effectively disables
+      the download step.
+
+    *URL Download*
+      ``URL <url1> [<url2>...]``
+        List of paths and/or URL(s) of the external project's source. When more
+        than one URL is given, they are tried in turn until one succeeds. A URL
+        may be an ordinary path in the local file system (in which case it
+        must be the only URL provided) or any downloadable URL supported by the
+        :command:`file(DOWNLOAD)` command. A local filesystem path may refer to
+        either an existing directory or to an archive file, whereas a URL is
+        expected to point to a file which can be treated as an archive. When an
+        archive is used, it will be unpacked automatically unless the
+        ``DOWNLOAD_NO_EXTRACT`` option is set to prevent it. The archive type
+        is determined by inspecting the actual content rather than using logic
+        based on the file extension.
+
+      ``URL_HASH <algo>=<hashValue>``
+        Hash of the archive file to be downloaded. The argument should be of
+        the form ``<algo>=<hashValue>`` where ``algo`` can be any of the hashing
+        algorithms supported by the :command:`file()` command. Specifying this
+        option is strongly recommended for URL downloads, as it ensures the
+        integrity of the downloaded content. It is also used as a check for a
+        previously downloaded file, allowing connection to the remote location
+        to be avoided altogether if the local directory already has a file from
+        an earlier download that matches the specified hash.
+
+      ``URL_MD5 <md5>``
+        Equivalent to ``URL_HASH MD5=<md5>``.
+
+      ``DOWNLOAD_NAME <fname>``
+        File name to use for the downloaded file. If not given, the end of the
+        URL is used to determine the file name. This option is rarely needed,
+        the default name is generally suitable and is not normally used outside
+        of code internal to the ``ExternalProject`` module.
+
+      ``DOWNLOAD_NO_EXTRACT <bool>``
+        Allows the extraction part of the download step to be disabled by
+        passing a boolean true value for this option. If this option is not
+        given, the downloaded contents will be unpacked automatically if
+        required. If extraction has been disabled, the full path to the
+        downloaded file is available as ``<DOWNLOADED_FILE>`` in subsequent
+        steps or as the property ``DOWNLOADED_FILE`` with the
+        :command:`ExternalProject_Get_Property` command.
+
+      ``DOWNLOAD_NO_PROGRESS <bool>``
+        Can be used to disable logging the download progress. If this option is
+        not given, download progress messages will be logged.
+
+      ``TIMEOUT <seconds>``
+        Maximum time allowed for file download operations.
+
+      ``HTTP_USERNAME <username>``
+        Username for the download operation if authentication is required.
+
+      ``HTTP_PASSWORD <password>``
+        Password for the download operation if authentication is required.
+
+      ``HTTP_HEADER <header1> [<header2>...]``
+        Provides an arbitrary list of HTTP headers for the download operation.
+        This can be useful for accessing content in systems like AWS, etc.
+
+      ``TLS_VERIFY <bool>``
+        Specifies whether certificate verification should be performed for
+        https URLs. If this option is not provided, the default behavior is
+        determined by the ``CMAKE_TLS_VERIFY`` variable (see
+        :command:`file(DOWNLOAD)`). If that is also not set, certificate
+        verification will not be performed. In situations where ``URL_HASH``
+        cannot be provided, this option can be an alternative verification
+        measure.
+
+      ``TLS_CAINFO <file>``
+        Specify a custom certificate authority file to use if ``TLS_VERIFY``
+        is enabled. If this option is not specified, the value of the
+        ``CMAKE_TLS_CAINFO`` variable will be used instead (see
+        :command:`file(DOWNLOAD)`)
+
+      ``NETRC <level>``
+        Specify whether the ``.netrc`` file is to be used for operation.
+        If this option is not specified, the value of the ``CMAKE_NETRC``
+        variable will be used instead (see :command:`file(DOWNLOAD)`)
+        Valid levels are:
+
+        ``IGNORED``
+          The ``.netrc`` file is ignored.
+          This is the default.
+        ``OPTIONAL``
+          The ``.netrc`` file is optional, and information in the URL
+          is preferred.  The file will be scanned to find which ever
+          information is not specified in the URL.
+        ``REQUIRED``
+          The ``.netrc`` file is required, and information in the URL
+          is ignored.
+
+      ``NETRC_FILE <file>``
+        Specify an alternative ``.netrc`` file to the one in your home directory
+        if the ``NETRC`` level is ``OPTIONAL`` or ``REQUIRED``. If this option
+        is not specified, the value of the ``CMAKE_NETRC_FILE`` variable will
+        be used instead (see :command:`file(DOWNLOAD)`)
+
+    *Git*
+      NOTE: A git version of 1.6.5 or later is required if this download method
+      is used.
+
+      ``GIT_REPOSITORY <url>``
+        URL of the git repository. Any URL understood by the ``git`` command
+        may be used.
+
+      ``GIT_TAG <tag>``
+        Git branch name, tag or commit hash. Note that branch names and tags
+        should generally be specified as remote names (i.e. ``origin/myBranch``
+        rather than simply ``myBranch``). This ensures that if the remote end
+        has its tag moved or branch rebased or history rewritten, the local
+        clone will still be updated correctly. In general, however, specifying
+        a commit hash should be preferred for a number of reasons:
+
+        - If the local clone already has the commit corresponding to the hash,
+          no ``git fetch`` needs to be performed to check for changes each time
+          CMake is re-run. This can result in a significant speed up if many
+          external projects are being used.
+        - Using a specific git hash ensures that the main project's own history
+          is fully traceable to a specific point in the external project's
+          evolution. If a branch or tag name is used instead, then checking out
+          a specific commit of the main project doesn't necessarily pin the
+          whole build to a specific point in the life of the external project.
+          The lack of such deterministic behavior makes the main project lose
+          traceability and repeatability.
+
+        If ``GIT_SHALLOW`` is enabled then ``GIT_TAG`` works only with
+        branch names and tags.  A commit hash is not allowed.
+
+      ``GIT_REMOTE_NAME <name>``
+        The optional name of the remote. If this option is not specified, it
+        defaults to ``origin``.
+
+      ``GIT_SUBMODULES <module>...``
+        Specific git submodules that should also be updated. If this option is
+        not provided, all git submodules will be updated.
+
+      ``GIT_SHALLOW <bool>``
+        When this option is enabled, the ``git clone`` operation will be given
+        the ``--depth 1`` option. This performs a shallow clone, which avoids
+        downloading the whole history and instead retrieves just the commit
+        denoted by the ``GIT_TAG`` option.
+
+      ``GIT_PROGRESS <bool>``
+        When enabled, this option instructs the ``git clone`` operation to
+        report its progress by passing it the ``--progress`` option. Without
+        this option, the clone step for large projects may appear to make the
+        build stall, since nothing will be logged until the clone operation
+        finishes. While this option can be used to provide progress to prevent
+        the appearance of the build having stalled, it may also make the build
+        overly noisy if lots of external projects are used.
+
+      ``GIT_CONFIG <option1> [<option2>...]``
+        Specify a list of config options to pass to ``git clone``. Each option
+        listed will be transformed into its own ``--config <option>`` on the
+        ``git clone`` command line, with each option required to be in the
+        form ``key=value``.
+
+    *Subversion*
+      ``SVN_REPOSITORY <url>``
+        URL of the Subversion repository.
+
+      ``SVN_REVISION -r<rev>``
+        Revision to checkout from the Subversion repository.
+
+      ``SVN_USERNAME <username>``
+        Username for the Subversion checkout and update.
+
+      ``SVN_PASSWORD <password>``
+        Password for the Subversion checkout and update.
+
+      ``SVN_TRUST_CERT <bool>``
+        Specifies whether to trust the Subversion server site certificate. If
+        enabled, the ``--trust-server-cert`` option is passed to the ``svn``
+        checkout and update commands.
+
+    *Mercurial*
+      ``HG_REPOSITORY <url>``
+        URL of the mercurial repository.
+
+      ``HG_TAG <tag>``
+        Mercurial branch name, tag or commit id.
+
+    *CVS*
+      ``CVS_REPOSITORY <cvsroot>``
+        CVSROOT of the CVS repository.
+
+      ``CVS_MODULE <mod>``
+        Module to checkout from the CVS repository.
+
+      ``CVS_TAG <tag>``
+        Tag to checkout from the CVS repository.
+
+  **Update/Patch Step Options:**
+    Whenever CMake is re-run, by default the external project's sources will be
+    updated if the download method supports updates (e.g. a git repository
+    would be checked if the ``GIT_TAG`` does not refer to a specific commit).
+
+    ``UPDATE_COMMAND <cmd>...``
+      Overrides the download method's update step with a custom command.
+      The command may use
+      :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+    ``UPDATE_DISCONNECTED <bool>``
+      When enabled, this option causes the update step to be skipped. It does
+      not, however, prevent the download step. The update step can still be
+      added as a step target (see :command:`ExternalProject_Add_StepTargets`)
+      and called manually. This is useful if you want to allow developers to
+      build the project when disconnected from the network (the network may
+      still be needed for the download step though).
+
+      When this option is present, it is generally advisable to make the value
+      a cache variable under the developer's control rather than hard-coding
+      it. If this option is not present, the default value is taken from the
+      ``EP_UPDATE_DISCONNECTED`` directory property. If that is also not
+      defined, updates are performed as normal. The ``EP_UPDATE_DISCONNECTED``
+      directory property is intended as a convenience for controlling the
+      ``UPDATE_DISCONNECTED`` behavior for an entire section of a project's
+      directory hierarchy and may be a more convenient method of giving
+      developers control over whether or not to perform updates (assuming the
+      project also provides a cache variable or some other convenient method
+      for setting the directory property).
+
+    ``PATCH_COMMAND <cmd>...``
+      Specifies a custom command to patch the sources after an update. By
+      default, no patch command is defined. Note that it can be quite difficult
+      to define an appropriate patch command that performs robustly, especially
+      for download methods such as git where changing the ``GIT_TAG`` will not
+      discard changes from a previous patch, but the patch command will be
+      called again after updating to the new tag.
+
+  **Configure Step Options:**
+    The configure step is run after the download and update steps. By default,
+    the external project is assumed to be a CMake project, but this can be
+    overridden if required.
+
+    ``CONFIGURE_COMMAND <cmd>...``
+      The default configure command runs CMake with options based on the main
+      project. For non-CMake external projects, the ``CONFIGURE_COMMAND``
+      option must be used to override this behavior
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). For projects that require no configure step, specify this
+      option with an empty string as the command to execute.
+
+    ``CMAKE_COMMAND /.../cmake``
+      Specify an alternative cmake executable for the configure step (use an
+      absolute path). This is generally not recommended, since it is
+      usually desirable to use the same CMake version throughout the whole
+      build. This option is ignored if a custom configure command has been
+      specified with ``CONFIGURE_COMMAND``.
+
+    ``CMAKE_GENERATOR <gen>``
+      Override the CMake generator used for the configure step. Without this
+      option, the same generator as the main build will be used. This option is
+      ignored if a custom configure command has been specified with the
+      ``CONFIGURE_COMMAND`` option.
+
+    ``CMAKE_GENERATOR_PLATFORM <platform>``
+      Pass a generator-specific platform name to the CMake command (see
+      :variable:`CMAKE_GENERATOR_PLATFORM`). It is an error to provide this
+      option without the ``CMAKE_GENERATOR`` option.
+
+    ``CMAKE_GENERATOR_TOOLSET <toolset>``
+      Pass a generator-specific toolset name to the CMake command (see
+      :variable:`CMAKE_GENERATOR_TOOLSET`). It is an error to provide this
+      option without the ``CMAKE_GENERATOR`` option.
+
+    ``CMAKE_GENERATOR_INSTANCE <instance>``
+      Pass a generator-specific instance selection to the CMake command (see
+      :variable:`CMAKE_GENERATOR_INSTANCE`). It is an error to provide this
+      option without the ``CMAKE_GENERATOR`` option.
+
+    ``CMAKE_ARGS <arg>...``
+      The specified arguments are passed to the ``cmake`` command line. They
+      can be any argument the ``cmake`` command understands, not just cache
+      values defined by ``-D...`` arguments (see also
+      :manual:`CMake Options <cmake(1)>`). In addition, arguments may use
+      :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+    ``CMAKE_CACHE_ARGS <arg>...``
+      This is an alternate way of specifying cache variables where command line
+      length issues may become a problem. The arguments are expected to be in
+      the form ``-Dvar:STRING=value``, which are then transformed into
+      CMake :command:`set` commands with the ``FORCE`` option used. These
+      ``set()`` commands are written to a pre-load script which is then applied
+      using the :manual:`cmake -C <cmake(1)>` command line option. Arguments
+      may use :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+    ``CMAKE_CACHE_DEFAULT_ARGS <arg>...``
+      This is the same as the ``CMAKE_CACHE_ARGS`` option except the ``set()``
+      commands do not include the ``FORCE`` keyword. This means the values act
+      as initial defaults only and will not override any variables already set
+      from a previous run. Use this option with care, as it can lead to
+      different behavior depending on whether the build starts from a fresh
+      build directory or re-uses previous build contents.
+
+      If the CMake generator is the ``Green Hills MULTI`` and not overridden then
+      the orginal projects settings for the GHS toolset and target system
+      customization cache variables are propagated into the external project.
+
+    ``SOURCE_SUBDIR <dir>``
+      When no ``CONFIGURE_COMMAND`` option is specified, the configure step
+      assumes the external project has a ``CMakeLists.txt`` file at the top of
+      its source tree (i.e. in ``SOURCE_DIR``). The ``SOURCE_SUBDIR`` option
+      can be used to point to an alternative directory within the source tree
+      to use as the top of the CMake source tree instead. This must be a
+      relative path and it will be interpreted as being relative to
+      ``SOURCE_DIR``.  When ``BUILD_IN_SOURCE 1`` is specified, the
+      ``BUILD_COMMAND`` is used to point to an alternative directory within the
+      source tree.
+
+  **Build Step Options:**
+    If the configure step assumed the external project uses CMake as its build
+    system, the build step will also. Otherwise, the build step will assume a
+    Makefile-based build and simply run ``make`` with no arguments as the
+    default build step. This can be overridden with custom build commands if
+    required.
+
+    ``BUILD_COMMAND <cmd>...``
+      Overrides the default build command
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). If this option is not given, the default build command will
+      be chosen to integrate with the main build in the most appropriate way
+      (e.g. using recursive ``make`` for Makefile generators or
+      ``cmake --build`` if the project uses a CMake build). This option can be
+      specified with an empty string as the command to make the build step do
+      nothing.
+
+    ``BUILD_IN_SOURCE <bool>``
+      When this option is enabled, the build will be done directly within the
+      external project's source tree. This should generally be avoided, the use
+      of a separate build directory is usually preferred, but it can be useful
+      when the external project assumes an in-source build. The ``BINARY_DIR``
+      option should not be specified if building in-source.
+
+    ``BUILD_ALWAYS <bool>``
+      Enabling this option forces the build step to always be run. This can be
+      the easiest way to robustly ensure that the external project's own build
+      dependencies are evaluated rather than relying on the default
+      success timestamp-based method. This option is not normally needed unless
+      developers are expected to modify something the external project's build
+      depends on in a way that is not detectable via the step target
+      dependencies (e.g. ``SOURCE_DIR`` is used without a download method and
+      developers might modify the sources in ``SOURCE_DIR``).
+
+    ``BUILD_BYPRODUCTS <file>...``
+      Specifies files that will be generated by the build command but which
+      might or might not have their modification time updated by subsequent
+      builds. These ultimately get passed through as ``BYPRODUCTS`` to the
+      build step's own underlying call to :command:`add_custom_command`.
+
+  **Install Step Options:**
+    If the configure step assumed the external project uses CMake as its build
+    system, the install step will also. Otherwise, the install step will assume
+    a Makefile-based build and simply run ``make install`` as the default build
+    step. This can be overridden with custom install commands if required.
+
+    ``INSTALL_COMMAND <cmd>...``
+      The external project's own install step is invoked as part of the main
+      project's *build*. It is done after the external project's build step
+      and may be before or after the external project's test step (see the
+      ``TEST_BEFORE_INSTALL`` option below). The external project's install
+      rules are not part of the main project's install rules, so if anything
+      from the external project should be installed as part of the main build,
+      these need to be specified in the main build as additional
+      :command:`install` commands. The default install step builds the
+      ``install`` target of the external project, but this can be overridden
+      with a custom command using this option
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). Passing an empty string as the ``<cmd>`` makes the install
+      step do nothing.
+
+  **Test Step Options:**
+    The test step is only defined if at least one of the following ``TEST_...``
+    options are provided.
+
+    ``TEST_COMMAND <cmd>...``
+      Overrides the default test command
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). If this option is not given, the default behavior of the test
+      step is to build the external project's own ``test`` target. This option
+      can be specified with ``<cmd>`` as an empty string, which allows the test
+      step to still be defined, but it will do nothing. Do not specify any of
+      the other ``TEST_...`` options if providing an empty string as the test
+      command, but prefer to omit all ``TEST_...`` options altogether if the
+      test step target is not needed.
+
+    ``TEST_BEFORE_INSTALL <bool>``
+      When this option is enabled, the test step will be executed before the
+      install step. The default behavior is for the test step to run after the
+      install step.
+
+    ``TEST_AFTER_INSTALL <bool>``
+      This option is mainly useful as a way to indicate that the test step is
+      desired but all default behavior is sufficient. Specifying this option
+      with a boolean true value ensures the test step is defined and that it
+      comes after the install step. If both ``TEST_BEFORE_INSTALL`` and
+      ``TEST_AFTER_INSTALL`` are enabled, the latter is silently ignored.
+
+    ``TEST_EXCLUDE_FROM_MAIN <bool>``
+      If enabled, the main build's default ALL target will not depend on the
+      test step. This can be a useful way of ensuring the test step is defined
+      but only gets invoked when manually requested.
+
+  **Output Logging Options:**
+    Each of the following ``LOG_...`` options can be used to wrap the relevant
+    step in a script to capture its output to files. The log files will be
+    created in ``LOG_DIR`` if supplied or otherwise the ``STAMP_DIR``
+    directory with step-specific file names.
+
+    ``LOG_DOWNLOAD <bool>``
+      When enabled, the output of the download step is logged to files.
+
+    ``LOG_UPDATE <bool>``
+      When enabled, the output of the update step is logged to files.
+
+    ``LOG_PATCH <bool>``
+      When enabled, the output of the patch step is logged to files.
+
+    ``LOG_CONFIGURE <bool>``
+      When enabled, the output of the configure step is logged to files.
+
+    ``LOG_BUILD <bool>``
+      When enabled, the output of the build step is logged to files.
+
+    ``LOG_INSTALL <bool>``
+      When enabled, the output of the install step is logged to files.
+
+    ``LOG_TEST <bool>``
+      When enabled, the output of the test step is logged to files.
+
+    ``LOG_MERGED_STDOUTERR <bool>``
+      When enabled, stdout and stderr will be merged for any step whose
+      output is being logged to files.
+
+    ``LOG_OUTPUT_ON_FAILURE <bool>``
+      This option only has an effect if at least one of the other ``LOG_<step>``
+      options is enabled.  If an error occurs for a step which has logging to
+      file enabled, that step's output will be printed to the console if
+      ``LOG_OUTPUT_ON_FAILURE`` is set to true.  For cases where a large amount
+      of output is recorded, just the end of that output may be printed to the
+      console.
+
+  **Terminal Access Options:**
+    Steps can be given direct access to the terminal in some cases. Giving a
+    step access to the terminal may allow it to receive terminal input if
+    required, such as for authentication details not provided by other options.
+    With the :generator:`Ninja` generator, these options place the steps in the
+    ``console`` :prop_gbl:`job pool <JOB_POOLS>`. Each step can be given access
+    to the terminal individually via the following options:
+
+    ``USES_TERMINAL_DOWNLOAD <bool>``
+      Give the download step access to the terminal.
+
+    ``USES_TERMINAL_UPDATE <bool>``
+      Give the update step access to the terminal.
+
+    ``USES_TERMINAL_CONFIGURE <bool>``
+      Give the configure step access to the terminal.
+
+    ``USES_TERMINAL_BUILD <bool>``
+      Give the build step access to the terminal.
+
+    ``USES_TERMINAL_INSTALL <bool>``
+      Give the install step access to the terminal.
+
+    ``USES_TERMINAL_TEST <bool>``
+      Give the test step access to the terminal.
+
+  **Target Options:**
+    ``DEPENDS <targets>...``
+      Specify other targets on which the external project depends. The other
+      targets will be brought up to date before any of the external project's
+      steps are executed. Because the external project uses additional custom
+      targets internally for each step, the ``DEPENDS`` option is the most
+      convenient way to ensure all of those steps depend on the other targets.
+      Simply doing
+      :command:`add_dependencies(\<name\> \<targets\>) <add_dependencies>` will
+      not make any of the steps dependent on ``<targets>``.
+
+    ``EXCLUDE_FROM_ALL <bool>``
+      When enabled, this option excludes the external project from the default
+      ALL target of the main build.
+
+    ``STEP_TARGETS <step-target>...``
+      Generate custom targets for the specified steps. This is required if the
+      steps need to be triggered manually or if they need to be used as
+      dependencies of other targets. If this option is not specified, the
+      default value is taken from the ``EP_STEP_TARGETS`` directory property.
+      See :command:`ExternalProject_Add_Step` below for further discussion of
+      the effects of this option.
+
+    ``INDEPENDENT_STEP_TARGETS <step-target>...``
+      Generate custom targets for the specified steps and prevent these targets
+      from having the usual dependencies applied to them. If this option is not
+      specified, the default value is taken from the
+      ``EP_INDEPENDENT_STEP_TARGETS`` directory property. This option is mostly
+      useful for allowing individual steps to be driven independently, such as
+      for a CDash setup where each step should be initiated and reported
+      individually rather than as one whole build. See
+      :command:`ExternalProject_Add_Step` below for further discussion of the
+      effects of this option.
+
+  **Miscellaneous Options:**
+    ``LIST_SEPARATOR <sep>``
+      For any of the various ``..._COMMAND`` options, replace ``;`` with
+      ``<sep>`` in the specified command lines. This can be useful where list
+      variables may be given in commands where they should end up as
+      space-separated arguments (``<sep>`` would be a single space character
+      string in this case).
+
+    ``COMMAND <cmd>...``
+      Any of the other ``..._COMMAND`` options can have additional commands
+      appended to them by following them with as many ``COMMAND ...`` options
+      as needed
+      (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+      supported). For example:
+
+      .. code-block:: cmake
+
+        ExternalProject_Add(example
+          ... # Download options, etc.
+          BUILD_COMMAND ${CMAKE_COMMAND} -E echo "Starting $<CONFIG> build"
+          COMMAND       ${CMAKE_COMMAND} --build <BINARY_DIR> --config $<CONFIG>
+          COMMAND       ${CMAKE_COMMAND} -E echo "$<CONFIG> build complete"
+        )
+
+  It should also be noted that each build step is created via a call to
+  :command:`ExternalProject_Add_Step`. See that command's documentation for the
+  automatic substitutions that are supported for some options.
+
+Obtaining Project Properties
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. command:: ExternalProject_Get_Property
+
+  The ``ExternalProject_Get_Property()`` function retrieves external project
+  target properties:
+
+  .. code-block:: cmake
+
+    ExternalProject_Get_Property(<name> <prop1> [<prop2>...])
+
+  The function stores property values in variables of the same name. Property
+  names correspond to the keyword argument names of ``ExternalProject_Add()``.
+  For example, the source directory might be retrieved like so:
+
+  .. code-block:: cmake
+
+    ExternalProject_Get_property(myExtProj SOURCE_DIR)
+    message("Source dir of myExtProj = ${SOURCE_DIR}")
+
+Explicit Step Management
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``ExternalProject_Add()`` function on its own is often sufficient for
+incorporating an external project into the main build. Certain scenarios
+require additional work to implement desired behavior, such as adding in a
+custom step or making steps available as manually triggerable targets. The
+``ExternalProject_Add_Step()``, ``ExternalProject_Add_StepTargets()`` and
+``ExternalProject_Add_StepDependencies`` functions provide the lower level
+control needed to implement such step-level capabilities.
 
 .. command:: ExternalProject_Add_Step
 
-  The ``ExternalProject_Add_Step`` function adds a custom step to an
-  external project::
+  The ``ExternalProject_Add_Step()`` function specifies an additional custom
+  step for an external project defined by an earlier call to
+  :command:`ExternalProject_Add`:
+
+  .. code-block:: cmake
 
-   ExternalProject_Add_Step(<name> <step> [<option>...])
+    ExternalProject_Add_Step(<name> <step> [<option>...])
 
-  Options are:
+  ``<name>`` is the same as the name passed to the original call to
+  :command:`ExternalProject_Add`. The specified ``<step>`` must not be one of
+  the pre-defined steps (``mkdir``, ``download``, ``update``, ``skip-update``,
+  ``patch``, ``configure``, ``build``, ``install`` or ``test``). The supported
+  options are:
 
   ``COMMAND <cmd>...``
-    Command line invoked by this step
+    The command line to be executed by this custom step
+    (:manual:`generator expressions <cmake-generator-expressions(7)>` are
+    supported). This option can be repeated multiple times to specify multiple
+    commands to be executed in order.
+
   ``COMMENT "<text>..."``
-    Text printed when step executes
+    Text to be printed when the custom step executes.
+
   ``DEPENDEES <step>...``
-    Steps on which this step depends
+    Other steps (custom or pre-defined) on which this step depends.
+
   ``DEPENDERS <step>...``
-    Steps that depend on this step
+    Other steps (custom or pre-defined) that depend on this new custom step.
+
   ``DEPENDS <file>...``
-    Files on which this step depends
+    Files on which this custom step depends.
+
   ``BYPRODUCTS <file>...``
-    Files that will be generated by this step but may or may not
-    have their modification time updated by subsequent builds.
-  ``ALWAYS 1``
-    No stamp file, step always runs
-  ``EXCLUDE_FROM_MAIN 1``
-    Main target does not depend on this step
+    Files that will be generated by this custom step but which might or might
+    not have their modification time updated by subsequent builds. This list of
+    files will ultimately be passed through as the ``BYPRODUCTS`` option to the
+    :command:`add_custom_command` used to implement the custom step internally.
+
+  ``ALWAYS <bool>``
+    When enabled, this option specifies that the custom step should always be
+    run (i.e. that it is always considered out of date).
+
+  ``EXCLUDE_FROM_MAIN <bool>``
+    When enabled, this option specifies that the external project's main target
+    does not depend on the custom step.
+
   ``WORKING_DIRECTORY <dir>``
-    Working directory for command
-  ``LOG 1``
-    Wrap step in script to log output
-  ``USES_TERMINAL 1``
-    Give the step direct access to the terminal if possible.
+    Specifies the working directory to set before running the custom step's
+    command. If this option is not specified, the directory will be the value
+    of the :variable:`CMAKE_CURRENT_BINARY_DIR` at the point where
+    ``ExternalProject_Add_Step()`` was called.
+
+  ``LOG <bool>``
+    If set, this causes the output from the custom step to be captured to files
+    in the external project's ``LOG_DIR`` if supplied or ``STAMP_DIR``.
+
+  ``USES_TERMINAL <bool>``
+    If enabled, this gives the custom step direct access to the terminal if
+    possible.
+
+  The command line, comment, working directory and byproducts of every
+  standard and custom step are processed to replace the tokens
+  ``<SOURCE_DIR>``, ``<SOURCE_SUBDIR>``, ``<BINARY_DIR>``, ``<INSTALL_DIR>``
+  ``<TMP_DIR>``, ``<DOWNLOAD_DIR>`` and ``<DOWNLOADED_FILE>`` with their
+  corresponding property values defined in the original call to
+  :command:`ExternalProject_Add`.
 
-  The command line, comment, working directory, and byproducts of every
-  standard and custom step are processed to replace tokens ``<SOURCE_DIR>``,
-  ``<SOURCE_SUBDIR>``,  ``<BINARY_DIR>``, ``<INSTALL_DIR>``, and ``<TMP_DIR>``
-  with corresponding property values.
+.. command:: ExternalProject_Add_StepTargets
 
-Any builtin step that specifies a ``<step>_COMMAND cmd...`` or custom
-step that specifies a ``COMMAND cmd...`` may specify additional command
-lines using the form ``COMMAND cmd...``.  At build time the commands
-will be executed in order and aborted if any one fails.  For example::
+  The ``ExternalProject_Add_StepTargets()`` function generates targets for the
+  steps listed. The name of each created target will be of the form
+  ``<name>-<step>``:
+
+  .. code-block:: cmake
+
+    ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] <step1> [<step2>...])
+
+  Creating a target for a step allows it to be used as a dependency of another
+  target or to be triggered manually. Having targets for specific steps also
+  allows them to be driven independently of each other by specifying targets on
+  build command lines. For example, you may be submitting to a sub-project
+  based dashboard where you want to drive the configure portion of the build,
+  then submit to the dashboard, followed by the build portion, followed
+  by tests. If you invoke a custom target that depends on a step halfway
+  through the step dependency chain, then all the previous steps will also run
+  to ensure everything is up to date.
+
+  If the ``NO_DEPENDS`` option is specified, the step target will not depend on
+  the dependencies of the external project (i.e. on any dependencies of the
+  ``<name>`` custom target created by :command:`ExternalProject_Add`). This is
+  usually safe for the ``download``, ``update`` and ``patch`` steps, since they
+  do not typically require that the dependencies are updated and built. Using
+  ``NO_DEPENDS`` for any of the other pre-defined steps, however, may break
+  parallel builds. Only use ``NO_DEPENDS`` where it is certain that the named
+  steps genuinely do not have dependencies. For custom steps, consider whether
+  or not the custom commands require the dependencies to be configured, built
+  and installed.
+
+  Internally, :command:`ExternalProject_Add` calls
+  :command:`ExternalProject_Add_Step` to create each step. If any
+  ``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` were specified, then
+  ``ExternalProject_Add_StepTargets()`` will also be called after
+  :command:`ExternalProject_Add_Step`. ``INDEPENDENT_STEP_TARGETS`` have the
+  ``NO_DEPENDS`` option set, whereas ``STEP_TARGETS`` do not. Other than that,
+  the two options result in ``ExternalProject_Add_StepTargets()`` being called
+  in the same way. Even if a step is not mentioned in either of those two
+  options, ``ExternalProject_Add_StepTargets()`` can still be called later to
+  manually define a target for the step.
+
+  The ``STEP_TARGETS`` and ``INDEPENDENT_STEP_TARGETS`` options for
+  :command:`ExternalProject_Add` are generally the easiest way to ensure
+  targets are created for specific steps of interest. For custom steps,
+  ``ExternalProject_Add_StepTargets()`` must be called explicitly if a target
+  should also be created for that custom step. An alternative to these two
+  options is to populate the ``EP_STEP_TARGETS`` and
+  ``EP_INDEPENDENT_STEP_TARGETS`` directory properties. These act as defaults
+  for the step target options and can save having to repeatedly specify the
+  same set of step targets when multiple external projects are being defined.

-Whether the current working directory is preserved between commands is

+  The ``ExternalProject_Add_StepDependencies()`` function can be used to add

+  knows about (these can be ordinary executable or library targets, custom
+  targets or even step targets of another external project):

-  The ``ExternalProject_Get_Property`` function retrieves external project
-  target properties::
+  This function takes care to set both target and file level dependencies and
+  will ensure that parallel builds will not break. It should be used instead of

-    ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] [step1 [step2 [...]]])
-
-If ``NO_DEPENDS`` is set, the target will not depend on the
-dependencies of the complete project. This is usually safe to use for
-the download, update, and patch steps that do not require that all the
-dependencies are updated and built.  Using ``NO_DEPENDS`` for other
-of the default steps might break parallel builds, so you should avoid,
-it.  For custom steps, you should consider whether or not the custom
-commands requires that the dependencies are configured, built and
-installed.
-
-If ``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` is set then
-``ExternalProject_Add_StepTargets`` is automatically called at the end
-of matching calls to ``ExternalProject_Add_Step``.  Pass
-``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` explicitly to
-individual ``ExternalProject_Add`` calls, or implicitly to all
-``ExternalProject_Add`` calls by setting the directory properties
-``EP_STEP_TARGETS`` and ``EP_INDEPENDENT_STEP_TARGETS``.  The
-``INDEPENDENT`` version of the argument and of the property will call
-``ExternalProject_Add_StepTargets`` with the ``NO_DEPENDS`` argument.
-
-If ``STEP_TARGETS`` and ``INDEPENDENT_STEP_TARGETS`` are not set,
-clients may still manually call ``ExternalProject_Add_StepTargets``
-after calling ``ExternalProject_Add`` or ``ExternalProject_Add_Step``.
-
-This functionality is provided to make it easy to drive the steps
-independently of each other by specifying targets on build command
-lines.  For example, you may be submitting to a sub-project based
-dashboard, where you want to drive the configure portion of the build,
-then submit to the dashboard, followed by the build portion, followed
-by tests.  If you invoke a custom target that depends on a step
-halfway through the step dependency chain, then all the previous steps
-will also run to ensure everything is up to date.
-
-For example, to drive configure, build and test steps independently
-for each ``ExternalProject_Add`` call in your project, write the following
-line prior to any ``ExternalProject_Add`` calls in your ``CMakeLists.txt``
-file::
-
- set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)
+  include(ExternalProject)
+  ExternalProject_Add(foobar

-.. command:: ExternalProject_Add_StepDependencies
+For the sake of the example, also define a second hypothetical external project
+called *SecretSauce*, which is downloaded from a web server. Two URLs are given
+to take advantage of a faster internal network if available, with a fallback to
+a slower external server. The project is a typical ``Makefile`` project with no
+configure step, so some of the default commands are overridden. The build is
+only required to build the *sauce* target:
+
+.. code-block:: cmake
+
+  find_program(MAKE_EXE NAMES gmake nmake make)
+  ExternalProject_Add(secretsauce
+    URL               http://intranet.somecompany.com/artifacts/sauce-2.7.tgz
+                      https://www.somecompany.com/downloads/sauce-2.7.zip
+    URL_HASH          MD5=d41d8cd98f00b204e9800998ecf8427e
+    CONFIGURE_COMMAND ""
+    BUILD_COMMAND     ${MAKE_EXE} sauce
+  )
+
+Suppose the build step of ``secretsauce`` requires that ``foobar`` must already
+be built. This could be enforced like so:
+
+.. code-block:: cmake
+
+  ExternalProject_Add_StepDependencies(secretsauce build foobar)
+
+Another alternative would be to create a custom target for ``foobar``'s build
+step and make ``secretsauce`` depend on that rather than the whole ``foobar``
+project. This would mean ``foobar`` only needs to be built, it doesn't need to
+run its install or test steps before ``secretsauce`` can be built. The
+dependency can also be defined along with the ``secretsauce`` project:
+
+.. code-block:: cmake
+
+  ExternalProject_Add_StepTargets(foobar build)
+  ExternalProject_Add(secretsauce
+    URL               http://intranet.somecompany.com/artifacts/sauce-2.7.tgz
+                      https://www.somecompany.com/downloads/sauce-2.7.zip
+    URL_HASH          MD5=d41d8cd98f00b204e9800998ecf8427e
+    CONFIGURE_COMMAND ""
+    BUILD_COMMAND     ${MAKE_EXE} sauce
+    DEPENDS           foobar-build
+  )
+
+Instead of calling :command:`ExternalProject_Add_StepTargets`, the target could
+be defined along with the ``foobar`` project itself:
+
+.. code-block:: cmake
+
+  ExternalProject_Add(foobar
+    GIT_REPOSITORY git@github.com:FooCo/FooBar.git
+    GIT_TAG        origin/release/1.2.3
+    STEP_TARGETS   build
+  )
+
+If many external projects should have the same set of step targets, setting a
+directory property may be more convenient. The ``build`` step target could be
+created automatically by setting the ``EP_STEP_TARGETS`` directory property
+before creating the external projects with :command:`ExternalProject_Add`:
+
+.. code-block:: cmake
 
-  The ``ExternalProject_Add_StepDependencies`` function add some
-  dependencies for some external project step::
+  set_property(DIRECTORY PROPERTY EP_STEP_TARGETS build)
 
-    ExternalProject_Add_StepDependencies(<name> <step> [target1 [target2 [...]]])
+Lastly, suppose that ``secretsauce`` provides a script called ``makedoc`` which
+can be used to generate its own documentation. Further suppose that the script
+expects the output directory to be provided as the only parameter and that it
+should be run from the ``secretsauce`` source directory. A custom step and a
+custom target to trigger the script can be defined like so:
+
+.. code-block:: cmake
+
+  ExternalProject_Add_Step(secretsauce docs
+    COMMAND           <SOURCE_DIR>/makedoc <BINARY_DIR>
+    WORKING_DIRECTORY <SOURCE_DIR>
+    COMMENT           "Building secretsauce docs"
+    ALWAYS            TRUE
+    EXCLUDE_FROM_MAIN TRUE
+  )
+  ExternalProject_Add_StepTargets(secretsauce docs)
+
+The custom step could then be triggered from the main build like so::
+
+  cmake --build . --target secretsauce-docs
 
-  This function takes care to set both target and file level
-  dependencies, and will ensure that parallel builds will not break.
-  It should be used instead of :command:`add_dependencies()` when adding
-  a dependency for some of the step targets generated by
-  ``ExternalProject``.

-#                            displayed during compilation
-#
-# This module reads hints about search locations from variables::
-#
-#   BOOST_ROOT             - Preferred installation prefix
-#    (or BOOSTROOT)
-#   BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
-#   BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
-#   Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
-#                            specified by these hint variables. Default is OFF.
-#   Boost_ADDITIONAL_VERSIONS
-#                          - List of Boost versions not known to this module
-#                            (Boost install locations may contain the version)

-#   Boost_LIBRARY_DIR_DEBUG   - Directory containing debug Boost libraries

-#                                   case
-#   Boost::diagnostic_definitions - interface target to enable diagnostic
-#                                   information about Boost's automatic linking
-#                                   during compilation (adds BOOST_LIB_DIAGNOSTIC)
-#   Boost::disable_autolinking    - interface target to disable automatic
-#                                   linking with MSVC (adds BOOST_ALL_NO_LIB)
-#   Boost::dynamic_linking        - interface target to enable dynamic linking
-#                                   linking with MSVC (adds BOOST_ALL_DYN_LINK)
-#
-# Implicit dependencies such as Boost::filesystem requiring
-# Boost::system will be automatically detected and satisfied, even
-# if system is not specified when using find_package and if
-# Boost::system is not added to target_link_libraries.  If using
-# Boost::thread, then Thread::Thread will also be added automatically.
-#
-# It is important to note that the imported targets behave differently
-# than variables created by this module: multiple calls to
-# find_package(Boost) in the same directory or sub-directories with
-# different options (e.g. static or shared) will not override the
-# values of the targets created by the first call.
-#
-# Users may set these hints or results as cache entries.  Projects
-# should not read these entries directly but instead use the above
-# result variables.  Note that some hint names start in upper-case
-# "BOOST".  One may specify these as environment variables if they are
-# not specified as CMake variables or cache entries.
-#
-# This module first searches for the Boost header files using the above
-# hint variables (excluding BOOST_LIBRARYDIR) and saves the result in
-# Boost_INCLUDE_DIR.  Then it searches for requested component libraries
-# using the above hints (excluding BOOST_INCLUDEDIR and
-# Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR,
-# and the library name configuration settings below.  It saves the
-# library directories in Boost_LIBRARY_DIR_DEBUG and
-# Boost_LIBRARY_DIR_RELEASE and individual library
-# locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE.
-# When one changes settings used by previous searches in the same build
-# tree (excluding environment variables) this module discards previous
-# search results affected by the changes and searches again.
-#
-# Boost libraries come in many variants encoded in their file name.
-# Users or projects may tell this module which variant to find by
-# setting variables::
-#
-#   Boost_USE_MULTITHREADED  - Set to OFF to use the non-multithreaded
-#                              libraries ('mt' tag).  Default is ON.
-#   Boost_USE_STATIC_LIBS    - Set to ON to force the use of the static
-#                              libraries.  Default is OFF.
-#   Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use
-#                              libraries linked statically to the C++ runtime
-#                              ('s' tag).  Default is platform dependent.
-#   Boost_USE_DEBUG_RUNTIME  - Set to ON or OFF to specify whether to use
-#                              libraries linked to the MS debug C++ runtime
-#                              ('g' tag).  Default is ON.
-#   Boost_USE_DEBUG_PYTHON   - Set to ON to use libraries compiled with a
-#                              debug Python build ('y' tag). Default is OFF.
-#   Boost_USE_STLPORT        - Set to ON to use libraries compiled with
-#                              STLPort ('p' tag).  Default is OFF.
-#   Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
-#                            - Set to ON to use libraries compiled with
-#                              STLPort deprecated "native iostreams"
-#                              ('n' tag).  Default is OFF.
-#   Boost_COMPILER           - Set to the compiler-specific library suffix
-#                              (e.g. "-gcc43").  Default is auto-computed
-#                              for the C++ compiler in use.  A list may be
-#                              used if multiple compatible suffixes should
-#                              be tested for, in decreasing order of
-#                              preference.
-#   Boost_THREADAPI          - Suffix for "thread" component library name,
-#                              such as "pthread" or "win32".  Names with
-#                              and without this suffix will both be tried.
-#   Boost_NAMESPACE          - Alternate namespace used to build boost with
-#                              e.g. if set to "myboost", will search for
-#                              myboost_thread instead of boost_thread.
-#
-# Other variables one may set to control this module are::
-#
-#   Boost_DEBUG              - Set to ON to enable debug output from FindBoost.
-#                              Please enable this before filing any bug report.
-#   Boost_DETAILED_FAILURE_MSG
-#                            - Set to ON to add detailed information to the
-#                              failure message even when the REQUIRED option
-#                              is not given to the find_package call.
-#   Boost_REALPATH           - Set to ON to resolve symlinks for discovered
-#                              libraries to assist with packaging.  For example,
-#                              the "system" component library may be resolved to
-#                              "/usr/lib/libboost_system.so.1.42.0" instead of
-#                              "/usr/lib/libboost_system.so".  This does not
-#                              affect linking and should not be enabled unless
-#                              the user needs this information.
-#   Boost_LIBRARY_DIR        - Default value for Boost_LIBRARY_DIR_RELEASE and
-#                              Boost_LIBRARY_DIR_DEBUG.
-#
-# On Visual Studio and Borland compilers Boost headers request automatic
-# linking to corresponding libraries.  This requires matching libraries
-# to be linked explicitly or available in the link library search path.
-# In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve
-# dynamic linking.  Boost automatic linking typically requests static
-# libraries with a few exceptions (such as Boost.Python).  Use::
-#
-#   add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
-#
-# to ask Boost to report information about automatic linking requests.
-#
-# Example to find Boost headers only::
-#
-#   find_package(Boost 1.36.0)
-#   if(Boost_FOUND)
-#     include_directories(${Boost_INCLUDE_DIRS})
-#     add_executable(foo foo.cc)
-#   endif()
-#
-# Example to find Boost libraries and use imported targets::

+FindBoost
+---------
+
+Find Boost include dirs and libraries
+
+Use this module by invoking find_package with the form::
+
+  find_package(Boost
+    [version] [EXACT]      # Minimum or EXACT version e.g. 1.67.0
+    [REQUIRED]             # Fail with error if Boost is not found
+    [COMPONENTS <libs>...] # Boost libraries by their canonical name
+                           # e.g. "date_time" for "libboost_date_time"
+    [OPTIONAL_COMPONENTS <libs>...]
+                           # Optional Boost libraries by their canonical name)
+    )                      # e.g. "date_time" for "libboost_date_time"
+
+This module finds headers and requested component libraries OR a CMake
+package configuration file provided by a "Boost CMake" build.  For the
+latter case skip to the "Boost CMake" section below.  For the former
+case results are reported in variables::
+
+  Boost_FOUND            - True if headers and requested libraries were found
+  Boost_INCLUDE_DIRS     - Boost include directories
+  Boost_LIBRARY_DIRS     - Link directories for Boost libraries
+  Boost_LIBRARIES        - Boost component libraries to be linked
+  Boost_<C>_FOUND        - True if component <C> was found (<C> is upper-case)
+  Boost_<C>_LIBRARY      - Libraries to link for component <C> (may include
+                           target_link_libraries debug/optimized keywords)
+  Boost_VERSION_MACRO    - BOOST_VERSION value from boost/version.hpp
+  Boost_VERSION_STRING   - Boost version number in x.y.z format
+  Boost_VERSION          - if CMP0093 NEW => same as Boost_VERSION_STRING
+                           if CMP0093 OLD or unset => same as Boost_VERSION_MACRO
+  Boost_LIB_VERSION      - Version string appended to library filenames
+  Boost_VERSION_MAJOR    - Boost major version number (X in X.y.z)
+                           alias: Boost_MAJOR_VERSION
+  Boost_VERSION_MINOR    - Boost minor version number (Y in x.Y.z)
+                           alias: Boost_MINOR_VERSION
+  Boost_VERSION_PATCH    - Boost subminor version number (Z in x.y.Z)
+                           alias: Boost_SUBMINOR_VERSION
+  Boost_VERSION_COUNT    - Amount of version components (3)
+  Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows)
+                         - Pass to add_definitions() to have diagnostic
+                           information about Boost's automatic linking
+                           displayed during compilation
+
+Note that Boost Python components require a Python version suffix
+(Boost 1.67 and later), e.g. ``python36`` or ``python27`` for the
+versions built against Python 3.6 and 2.7, respectively.  This also
+applies to additional components using Python including
+``mpi_python`` and ``numpy``.  Earlier Boost releases may use
+distribution-specific suffixes such as ``2``, ``3`` or ``2.7``.
+These may also be used as suffixes, but note that they are not
+portable.
+
+This module reads hints about search locations from variables::
+
+  BOOST_ROOT             - Preferred installation prefix
+   (or BOOSTROOT)
+  BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
+  BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
+  Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
+                           specified by these hint variables. Default is OFF.
+  Boost_ADDITIONAL_VERSIONS
+                         - List of Boost versions not known to this module
+                           (Boost install locations may contain the version)
+
+and saves search results persistently in CMake cache entries::
+
+  Boost_INCLUDE_DIR         - Directory containing Boost headers
+  Boost_LIBRARY_DIR_RELEASE - Directory containing release Boost libraries
+  Boost_LIBRARY_DIR_DEBUG   - Directory containing debug Boost libraries
+  Boost_<C>_LIBRARY_DEBUG   - Component <C> library debug variant
+  Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant
+
+The following :prop_tgt:`IMPORTED` targets are also defined::
+
+  Boost::headers                - Target for header-only dependencies
+                                  (Boost include directory)
+                                  alias: Boost::boost
+  Boost::<C>                    - Target for specific component dependency
+                                  (shared or static library); <C> is lower-
+                                  case
+  Boost::diagnostic_definitions - interface target to enable diagnostic
+                                  information about Boost's automatic linking
+                                  during compilation (adds BOOST_LIB_DIAGNOSTIC)
+  Boost::disable_autolinking    - interface target to disable automatic
+                                  linking with MSVC (adds BOOST_ALL_NO_LIB)
+  Boost::dynamic_linking        - interface target to enable dynamic linking
+                                  linking with MSVC (adds BOOST_ALL_DYN_LINK)
+
+Implicit dependencies such as ``Boost::filesystem`` requiring
+``Boost::system`` will be automatically detected and satisfied, even
+if system is not specified when using :command:`find_package` and if
+``Boost::system`` is not added to :command:`target_link_libraries`.  If using
+``Boost::thread``, then ``Threads::Threads`` will also be added automatically.
+
+It is important to note that the imported targets behave differently
+than variables created by this module: multiple calls to
+:command:`find_package(Boost)` in the same directory or sub-directories with
+different options (e.g. static or shared) will not override the
+values of the targets created by the first call.
+
+Users may set these hints or results as ``CACHE`` entries.  Projects
+should not read these entries directly but instead use the above
+result variables.  Note that some hint names start in upper-case
+"BOOST".  One may specify these as environment variables if they are
+not specified as CMake variables or cache entries.
+
+This module first searches for the ``Boost`` header files using the above
+hint variables (excluding ``BOOST_LIBRARYDIR``) and saves the result in
+``Boost_INCLUDE_DIR``.  Then it searches for requested component libraries
+using the above hints (excluding ``BOOST_INCLUDEDIR`` and
+``Boost_ADDITIONAL_VERSIONS``), "lib" directories near ``Boost_INCLUDE_DIR``,
+and the library name configuration settings below.  It saves the
+library directories in ``Boost_LIBRARY_DIR_DEBUG`` and
+``Boost_LIBRARY_DIR_RELEASE`` and individual library
+locations in ``Boost_<C>_LIBRARY_DEBUG`` and ``Boost_<C>_LIBRARY_RELEASE``.
+When one changes settings used by previous searches in the same build
+tree (excluding environment variables) this module discards previous
+search results affected by the changes and searches again.
+
+Boost libraries come in many variants encoded in their file name.
+Users or projects may tell this module which variant to find by
+setting variables::
+
+  Boost_USE_DEBUG_LIBS     - Set to ON or OFF to specify whether to search
+                             and use the debug libraries.  Default is ON.
+  Boost_USE_RELEASE_LIBS   - Set to ON or OFF to specify whether to search
+                             and use the release libraries.  Default is ON.
+  Boost_USE_MULTITHREADED  - Set to OFF to use the non-multithreaded
+                             libraries ('mt' tag).  Default is ON.
+  Boost_USE_STATIC_LIBS    - Set to ON to force the use of the static
+                             libraries.  Default is OFF.
+  Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use
+                             libraries linked statically to the C++ runtime
+                             ('s' tag).  Default is platform dependent.
+  Boost_USE_DEBUG_RUNTIME  - Set to ON or OFF to specify whether to use
+                             libraries linked to the MS debug C++ runtime
+                             ('g' tag).  Default is ON.
+  Boost_USE_DEBUG_PYTHON   - Set to ON to use libraries compiled with a
+                             debug Python build ('y' tag). Default is OFF.
+  Boost_USE_STLPORT        - Set to ON to use libraries compiled with
+                             STLPort ('p' tag).  Default is OFF.
+  Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
+                           - Set to ON to use libraries compiled with
+                             STLPort deprecated "native iostreams"
+                             ('n' tag).  Default is OFF.
+  Boost_COMPILER           - Set to the compiler-specific library suffix
+                             (e.g. "-gcc43").  Default is auto-computed
+                             for the C++ compiler in use.  A list may be
+                             used if multiple compatible suffixes should
+                             be tested for, in decreasing order of
+                             preference.
+  Boost_ARCHITECTURE       - Set to the architecture-specific library suffix
+                             (e.g. "-x64").  Default is auto-computed for the
+                             C++ compiler in use.
+  Boost_THREADAPI          - Suffix for "thread" component library name,
+                             such as "pthread" or "win32".  Names with
+                             and without this suffix will both be tried.
+  Boost_NAMESPACE          - Alternate namespace used to build boost with
+                             e.g. if set to "myboost", will search for
+                             myboost_thread instead of boost_thread.
+
+Other variables one may set to control this module are::
+
+  Boost_DEBUG              - Set to ON to enable debug output from FindBoost.
+                             Please enable this before filing any bug report.
+  Boost_REALPATH           - Set to ON to resolve symlinks for discovered
+                             libraries to assist with packaging.  For example,
+                             the "system" component library may be resolved to
+                             "/usr/lib/libboost_system.so.1.67.0" instead of
+                             "/usr/lib/libboost_system.so".  This does not
+                             affect linking and should not be enabled unless
+                             the user needs this information.
+  Boost_LIBRARY_DIR        - Default value for Boost_LIBRARY_DIR_RELEASE and
+                             Boost_LIBRARY_DIR_DEBUG.
+
+On Visual Studio and Borland compilers Boost headers request automatic
+linking to corresponding libraries.  This requires matching libraries
+to be linked explicitly or available in the link library search path.
+In this case setting ``Boost_USE_STATIC_LIBS`` to ``OFF`` may not achieve
+dynamic linking.  Boost automatic linking typically requests static
+libraries with a few exceptions (such as ``Boost.Python``).  Use::
+
+  add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
+
+to ask Boost to report information about automatic linking requests.
+
+Example to find Boost headers only::
+
+  find_package(Boost 1.36.0)
+  if(Boost_FOUND)
+    include_directories(${Boost_INCLUDE_DIRS})
+    add_executable(foo foo.cc)
+  endif()
+
+Example to find Boost libraries and use imported targets::
+
+  find_package(Boost 1.56 REQUIRED COMPONENTS
+               date_time filesystem iostreams)
+  add_executable(foo foo.cc)
+  target_link_libraries(foo Boost::date_time Boost::filesystem
+                            Boost::iostreams)
+
+Example to find Boost Python 3.6 libraries and use imported targets::
+
+  find_package(Boost 1.67 REQUIRED COMPONENTS
+               python36 numpy36)
+  add_executable(foo foo.cc)
+  target_link_libraries(foo Boost::python36 Boost::numpy36)
+
+Example to find Boost headers and some *static* (release only) libraries::
+
+  set(Boost_USE_STATIC_LIBS        ON)  # only find static libs
+  set(Boost_USE_DEBUG_LIBS         OFF) # ignore debug libs and
+  set(Boost_USE_RELEASE_LIBS       ON)  # only find release libs
+  set(Boost_USE_MULTITHREADED      ON)
+  set(Boost_USE_STATIC_RUNTIME    OFF)
+  find_package(Boost 1.66.0 COMPONENTS date_time filesystem system ...)
+  if(Boost_FOUND)
+    include_directories(${Boost_INCLUDE_DIRS})
+    add_executable(foo foo.cc)
+    target_link_libraries(foo ${Boost_LIBRARIES})
+  endif()
+
+Boost CMake
+^^^^^^^^^^^
+
+If Boost was built using the boost-cmake project or from Boost 1.70.0 on
+it provides a package configuration file for use with find_package's config mode.
+This module looks for the package configuration file called
+``BoostConfig.cmake`` or ``boost-config.cmake`` and stores the result in
+``CACHE`` entry "Boost_DIR".  If found, the package configuration file is loaded
+and this module returns with no further action.  See documentation of
+the Boost CMake package configuration for details on what it provides.
+
+Set ``Boost_NO_BOOST_CMAKE`` to ``ON``, to disable the search for boost-cmake.

-# --------
-#
-# Tools for building CUDA C files: libraries and build dependencies.
-#
-# This script locates the NVIDIA CUDA C tools.  It should work on linux,
-# windows, and mac and should be reasonably up to date with CUDA C
-# releases.
-#
-# This script makes use of the standard find_package arguments of
-# <VERSION>, REQUIRED and QUIET.  CUDA_FOUND will report if an
-# acceptable version of CUDA was found.
-#
-# The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
-# the prefix cannot be determined by the location of nvcc in the system
-# path and REQUIRED is specified to find_package().  To use a different
-# installed version of the toolkit set the environment variable
-# CUDA_BIN_PATH before running cmake (e.g.
-# CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
-# /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.  If
-# you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
-# depend on the path will be relocated.
-#
-# It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
-# platforms, or to use a cuda runtime not installed in the default
-# location.  In newer versions of the toolkit the cuda library is
-# included with the graphics driver- be sure that the driver version
-# matches what is needed by the cuda runtime version.
-#
-# The following variables affect the behavior of the macros in the
-# script (in alphebetical order).  Note that any of these flags can be
-# changed multiple times in the same directory before calling
-# CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX,
-# CUDA_COMPILE_FATBIN, CUDA_COMPILE_CUBIN or CUDA_WRAP_SRCS::
-#
-#   CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
-#   -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
-#      Note that making this different from the host code when generating object
-#      or C files from CUDA code just won't work, because size_t gets defined by
-#      nvcc in the generated source.  If you compile to PTX and then load the
-#      file yourself, you can mix bit sizes between device and host.
-#
-#   CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
-#   -- Set to ON if you want the custom build rule to be attached to the source
-#      file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
-#      targets.
-#
-#      This allows the user to build the target from the CUDA file; however, bad
-#      things can happen if the CUDA source file is added to multiple targets.
-#      When performing parallel builds it is possible for the custom build
-#      command to be run more than once and in parallel causing cryptic build
-#      errors.  VS runs the rules for every source file in the target, and a
-#      source can have only one rule no matter how many projects it is added to.
-#      When the rule is run from multiple targets race conditions can occur on
-#      the generated file.  Eventually everything will get built, but if the user
-#      is unaware of this behavior, there may be confusion.  It would be nice if
-#      this script could detect the reuse of source files across multiple targets
-#      and turn the option off for the user, but no good solution could be found.
-#
-#   CUDA_BUILD_CUBIN (Default OFF)
-#   -- Set to ON to enable and extra compilation pass with the -cubin option in
-#      Device mode. The output is parsed and register, shared memory usage is
-#      printed during build.
-#
-#   CUDA_BUILD_EMULATION (Default OFF for device mode)
-#   -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
-#      when CUDA_BUILD_EMULATION is TRUE.
-#
-#   CUDA_LINK_LIBRARIES_KEYWORD (Default "")
-#    -- The <PRIVATE|PUBLIC|INTERFACE> keyword to use for internal
-#       target_link_libraries calls. The default is to use no keyword which
-#       uses the old "plain" form of target_link_libraries. Note that is matters
-#       because whatever is used inside the FindCUDA module must also be used
-#       outside - the two forms of target_link_libraries cannot be mixed.
-#
-#   CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
-#   -- Set to the path you wish to have the generated files placed.  If it is
-#      blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
-#      Intermediate files will always be placed in
-#      CMAKE_CURRENT_BINARY_DIR/CMakeFiles.
-#
-#   CUDA_HOST_COMPILATION_CPP (Default ON)
-#   -- Set to OFF for C compilation of host code.
-#
-#   CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
-#   -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
-#      --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
-#      CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets
-#      $(VCInstallDir)/bin is a special value that expands out to the path when
-#      the command is run from within VS.
-#
-#   CUDA_NVCC_FLAGS
-#   CUDA_NVCC_FLAGS_<CONFIG>
-#   -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
-#      semi-colon delimited (e.g. --compiler-options;-Wall)
-#
-#   CUDA_PROPAGATE_HOST_FLAGS (Default ON)
-#   -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
-#      dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
-#      host compiler through nvcc's -Xcompiler flag.  This helps make the
-#      generated host code match the rest of the system better.  Sometimes
-#      certain flags give nvcc problems, and this will help you turn the flag
-#      propagation off.  This does not affect the flags supplied directly to nvcc
-#      via CUDA_NVCC_FLAGS or through the OPTION flags specified through
-#      CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
-#      shared library compilation are not affected by this flag.
-#
-#   CUDA_SEPARABLE_COMPILATION (Default OFF)
-#   -- If set this will enable separable compilation for all CUDA runtime object
-#      files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
-#      (e.g. calling CUDA_WRAP_SRCS directly),
-#      CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
-#      CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.
-#
-#   CUDA_SOURCE_PROPERTY_FORMAT
-#   -- If this source file property is set, it can override the format specified
-#      to CUDA_WRAP_SRCS (OBJ, PTX, CUBIN, or FATBIN).  If an input source file
-#      is not a .cu file, setting this file will cause it to be treated as a .cu
-#      file. See documentation for set_source_files_properties on how to set
-#      this property.
-#
-#   CUDA_USE_STATIC_CUDA_RUNTIME (Default ON)
-#   -- When enabled the static version of the CUDA runtime library will be used
-#      in CUDA_LIBRARIES.  If the version of CUDA configured doesn't support
-#      this option, then it will be silently disabled.
-#
-#   CUDA_VERBOSE_BUILD (Default OFF)
-#   -- Set to ON to see all the commands used when building the CUDA file.  When
-#      using a Makefile generator the value defaults to VERBOSE (run make
-#      VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
-#      always print the output.
-#
-# The script creates the following macros (in alphebetical order)::
-#
-#   CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
-#   -- Adds the cufft library to the target (can be any target).  Handles whether

-#
-#   CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
-#   -- Adds the cublas library to the target (can be any target).  Handles

-#                        [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-#   -- Creates an executable "cuda_target" which is made up of the files

-#      build rules specified by CMAKE and the cuda files are compiled to object
-#      files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
-#      added automatically to include_directories().  Some standard CMake target
-#      calls can be used on the target after calling this macro
-#      (e.g. set_target_properties and target_link_libraries), but setting
-#      properties that adjust compilation flags will not affect code compiled by
-#      nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,

-#      automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
-#      this is a function and not a macro.
-#
-#   CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
-#   -- Sets the directories that should be passed to nvcc
-#      (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
-#      files.
-#
-#
-#   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
-#                                            nvcc_flags object_files)
-#   -- Generates the link object required by separable compilation from the given
-#      object files.  This is called automatically for CUDA_ADD_EXECUTABLE and

-#      directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
-#      nvcc_flags passed in are the same as the flags passed in via the OPTIONS
-#      argument.  The only nvcc flag added automatically is the bitness flag as

-#      instead of a macro.

-#   CUDA_SELECT_NVCC_ARCH_FLAGS(out_variable [target_CUDA_architectures])
-#   -- Selects GPU arch flags for nvcc based on target_CUDA_architectures

-#
-#      More info on CUDA architectures: https://en.wikipedia.org/wiki/CUDA
-#      Note that this is a function instead of a macro.
-#
-#   CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
-#                    [STATIC | SHARED | MODULE] [OPTIONS ...] )
-#   -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
-#      CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
-#      function under the hood.
-#
-#      Given the list of files (file0 file1 ... fileN) this macro generates
-#      custom commands that generate either PTX or linkable objects (use "PTX" or
-#      "OBJ" for the format argument to switch).  Files that don't end with .cu
-#      or have the HEADER_FILE_ONLY property are ignored.
-#
-#      The arguments passed in after OPTIONS are extra command line options to
-#      give to nvcc.  You can also specify per configuration options by
-#      specifying the name of the configuration followed by the options.  General
-#      options must precede configuration specific options.  Not all
-#      configurations need to be specified, only the ones provided will be used.

-#         RELEASE --use_fast_math
-#         RELWITHDEBINFO --use_fast_math;-g

-#
-#      For certain configurations (namely VS generating object files with
-#      CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
-#      be produced for the given cuda file.  This is because when you add the
-#      cuda file to Visual Studio it knows that this file produces an object file
-#      and will link in the resulting object file automatically.
-#
-#      This script will also generate a separate cmake script that is used at
-#      build time to invoke nvcc.  This is for several reasons.

+
+Replacement
+^^^^^^^^^^^
+
+It is no longer necessary to use this module or call ``find_package(CUDA)``.
+Instead, list ``CUDA`` among the languages named in the top-level
+call to the :command:`project` command, or call the
+:command:`enable_language` command with ``CUDA``.
+Then one can add CUDA (``.cu``) sources to programs directly
+in calls to :command:`add_library` and :command:`add_executable`.
+
+Documentation of Deprecated Usage
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Tools for building CUDA C files: libraries and build dependencies.
+
+This script locates the NVIDIA CUDA C tools.  It should work on Linux,
+Windows, and macOS and should be reasonably up to date with CUDA C
+releases.
+
+This script makes use of the standard :command:`find_package` arguments of
+``<VERSION>``, ``REQUIRED`` and ``QUIET``.  ``CUDA_FOUND`` will report if an
+acceptable version of CUDA was found.
+
+The script will prompt the user to specify ``CUDA_TOOLKIT_ROOT_DIR`` if
+the prefix cannot be determined by the location of nvcc in the system
+path and ``REQUIRED`` is specified to :command:`find_package`.  To use
+a different installed version of the toolkit set the environment variable
+``CUDA_BIN_PATH`` before running cmake (e.g.
+``CUDA_BIN_PATH=/usr/local/cuda1.0`` instead of the default
+``/usr/local/cuda``) or set ``CUDA_TOOLKIT_ROOT_DIR`` after configuring.  If
+you change the value of ``CUDA_TOOLKIT_ROOT_DIR``, various components that
+depend on the path will be relocated.
+
+It might be necessary to set ``CUDA_TOOLKIT_ROOT_DIR`` manually on certain
+platforms, or to use a CUDA runtime not installed in the default
+location.  In newer versions of the toolkit the CUDA library is
+included with the graphics driver -- be sure that the driver version
+matches what is needed by the CUDA runtime version.
+
+The following variables affect the behavior of the macros in the
+script (in alphabetical order).  Note that any of these flags can be
+changed multiple times in the same directory before calling
+``CUDA_ADD_EXECUTABLE``, ``CUDA_ADD_LIBRARY``, ``CUDA_COMPILE``,
+``CUDA_COMPILE_PTX``, ``CUDA_COMPILE_FATBIN``, ``CUDA_COMPILE_CUBIN``
+or ``CUDA_WRAP_SRCS``::
+
+  CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
+  -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
+     Note that making this different from the host code when generating object
+     or C files from CUDA code just won't work, because size_t gets defined by
+     nvcc in the generated source.  If you compile to PTX and then load the
+     file yourself, you can mix bit sizes between device and host.
+
+  CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
+  -- Set to ON if you want the custom build rule to be attached to the source
+     file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
+     targets.
+
+     This allows the user to build the target from the CUDA file; however, bad
+     things can happen if the CUDA source file is added to multiple targets.
+     When performing parallel builds it is possible for the custom build
+     command to be run more than once and in parallel causing cryptic build
+     errors.  VS runs the rules for every source file in the target, and a
+     source can have only one rule no matter how many projects it is added to.
+     When the rule is run from multiple targets race conditions can occur on
+     the generated file.  Eventually everything will get built, but if the user
+     is unaware of this behavior, there may be confusion.  It would be nice if
+     this script could detect the reuse of source files across multiple targets
+     and turn the option off for the user, but no good solution could be found.
+
+  CUDA_BUILD_CUBIN (Default OFF)
+  -- Set to ON to enable and extra compilation pass with the -cubin option in
+     Device mode. The output is parsed and register, shared memory usage is
+     printed during build.
+
+  CUDA_BUILD_EMULATION (Default OFF for device mode)
+  -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
+     when CUDA_BUILD_EMULATION is TRUE.
+
+  CUDA_LINK_LIBRARIES_KEYWORD (Default "")
+   -- The <PRIVATE|PUBLIC|INTERFACE> keyword to use for internal
+      target_link_libraries calls. The default is to use no keyword which
+      uses the old "plain" form of target_link_libraries. Note that is matters
+      because whatever is used inside the FindCUDA module must also be used
+      outside - the two forms of target_link_libraries cannot be mixed.
+
+  CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
+  -- Set to the path you wish to have the generated files placed.  If it is
+     blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
+     Intermediate files will always be placed in
+     CMAKE_CURRENT_BINARY_DIR/CMakeFiles.
+
+  CUDA_HOST_COMPILATION_CPP (Default ON)
+  -- Set to OFF for C compilation of host code.
+
+  CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER)
+  -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
+     --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
+     CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets,
+     the host compiler is constructed with one or more visual studio macros
+     such as $(VCInstallDir), that expands out to the path when
+     the command is run from within VS.
+     If the CUDAHOSTCXX environment variable is set it will
+     be used as the default.
+
+  CUDA_NVCC_FLAGS
+  CUDA_NVCC_FLAGS_<CONFIG>
+  -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
+     semi-colon delimited (e.g. --compiler-options;-Wall)
+
+  CUDA_PROPAGATE_HOST_FLAGS (Default ON)
+  -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
+     dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
+     host compiler through nvcc's -Xcompiler flag.  This helps make the
+     generated host code match the rest of the system better.  Sometimes
+     certain flags give nvcc problems, and this will help you turn the flag
+     propagation off.  This does not affect the flags supplied directly to nvcc
+     via CUDA_NVCC_FLAGS or through the OPTION flags specified through
+     CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
+     shared library compilation are not affected by this flag.
+
+  CUDA_SEPARABLE_COMPILATION (Default OFF)
+  -- If set this will enable separable compilation for all CUDA runtime object
+     files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
+     (e.g. calling CUDA_WRAP_SRCS directly),
+     CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
+     CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.
+
+  CUDA_SOURCE_PROPERTY_FORMAT
+  -- If this source file property is set, it can override the format specified
+     to CUDA_WRAP_SRCS (OBJ, PTX, CUBIN, or FATBIN).  If an input source file
+     is not a .cu file, setting this file will cause it to be treated as a .cu
+     file. See documentation for set_source_files_properties on how to set
+     this property.
+
+  CUDA_USE_STATIC_CUDA_RUNTIME (Default ON)
+  -- When enabled the static version of the CUDA runtime library will be used
+     in CUDA_LIBRARIES.  If the version of CUDA configured doesn't support
+     this option, then it will be silently disabled.
+
+  CUDA_VERBOSE_BUILD (Default OFF)
+  -- Set to ON to see all the commands used when building the CUDA file.  When
+     using a Makefile generator the value defaults to VERBOSE (run make
+     VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
+     always print the output.
+
+The script creates the following macros (in alphabetical order)::
+
+  CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
+  -- Adds the cufft library to the target (can be any target).  Handles whether
+     you are in emulation mode or not.
+
+  CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
+  -- Adds the cublas library to the target (can be any target).  Handles
+     whether you are in emulation mode or not.
+
+  CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
+                       [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
+  -- Creates an executable "cuda_target" which is made up of the files
+     specified.  All of the non CUDA C files are compiled using the standard
+     build rules specified by CMAKE and the cuda files are compiled to object
+     files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
+     added automatically to include_directories().  Some standard CMake target
+     calls can be used on the target after calling this macro
+     (e.g. set_target_properties and target_link_libraries), but setting
+     properties that adjust compilation flags will not affect code compiled by
+     nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
+     CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.
+
+  CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
+                    [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
+  -- Same as CUDA_ADD_EXECUTABLE except that a library is created.
+
+  CUDA_BUILD_CLEAN_TARGET()
+  -- Creates a convenience target that deletes all the dependency files
+     generated.  You should make clean after running this target to ensure the
+     dependency files get regenerated.
+
+  CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
+                [OPTIONS ...] )
+  -- Returns a list of generated files from the input source files to be used
+     with ADD_LIBRARY or ADD_EXECUTABLE.
+
+  CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
+  -- Returns a list of PTX files generated from the input source files.
+
+  CUDA_COMPILE_FATBIN( generated_files file0 file1 ... [OPTIONS ...] )
+  -- Returns a list of FATBIN files generated from the input source files.
+
+  CUDA_COMPILE_CUBIN( generated_files file0 file1 ... [OPTIONS ...] )
+  -- Returns a list of CUBIN files generated from the input source files.
+
+  CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var
+                                                       cuda_target
+                                                       object_files )
+  -- Compute the name of the intermediate link file used for separable
+     compilation.  This file name is typically passed into
+     CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS.  output_file_var is produced
+     based on cuda_target the list of objects files that need separable
+     compilation as specified by object_files.  If the object_files list is
+     empty, then output_file_var will be empty.  This function is called
+     automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
+     this is a function and not a macro.
+
+  CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
+  -- Sets the directories that should be passed to nvcc
+     (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
+     files.
+
+
+  CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
+                                           nvcc_flags object_files)
+  -- Generates the link object required by separable compilation from the given
+     object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
+     CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
+     directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
+     nvcc_flags passed in are the same as the flags passed in via the OPTIONS
+     argument.  The only nvcc flag added automatically is the bitness flag as
+     specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
+     instead of a macro.
+
+  CUDA_SELECT_NVCC_ARCH_FLAGS(out_variable [target_CUDA_architectures])
+  -- Selects GPU arch flags for nvcc based on target_CUDA_architectures
+     target_CUDA_architectures : Auto | Common | All | LIST(ARCH_AND_PTX ...)
+      - "Auto" detects local machine GPU compute arch at runtime.
+      - "Common" and "All" cover common and entire subsets of architectures
+     ARCH_AND_PTX : NAME | NUM.NUM | NUM.NUM(NUM.NUM) | NUM.NUM+PTX
+     NAME: Fermi Kepler Maxwell Kepler+Tegra Kepler+Tesla Maxwell+Tegra Pascal
+     NUM: Any number. Only those pairs are currently accepted by NVCC though:
+           2.0 2.1 3.0 3.2 3.5 3.7 5.0 5.2 5.3 6.0 6.2
+     Returns LIST of flags to be added to CUDA_NVCC_FLAGS in ${out_variable}
+     Additionally, sets ${out_variable}_readable to the resulting numeric list
+     Example:
+      CUDA_SELECT_NVCC_ARCH_FLAGS(ARCH_FLAGS 3.0 3.5+PTX 5.2(5.0) Maxwell)
+       LIST(APPEND CUDA_NVCC_FLAGS ${ARCH_FLAGS})
+
+     More info on CUDA architectures: https://en.wikipedia.org/wiki/CUDA
+     Note that this is a function instead of a macro.
+
+  CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
+                   [STATIC | SHARED | MODULE] [OPTIONS ...] )
+  -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
+     CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
+     function under the hood.
+
+     Given the list of files (file0 file1 ... fileN) this macro generates
+     custom commands that generate either PTX or linkable objects (use "PTX" or
+     "OBJ" for the format argument to switch).  Files that don't end with .cu
+     or have the HEADER_FILE_ONLY property are ignored.
+
+     The arguments passed in after OPTIONS are extra command line options to
+     give to nvcc.  You can also specify per configuration options by
+     specifying the name of the configuration followed by the options.  General
+     options must precede configuration specific options.  Not all
+     configurations need to be specified, only the ones provided will be used.
+
+        OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
+        DEBUG -g
+        RELEASE --use_fast_math
+        RELWITHDEBINFO --use_fast_math;-g
+        MINSIZEREL --use_fast_math
+
+     For certain configurations (namely VS generating object files with
+     CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
+     be produced for the given cuda file.  This is because when you add the
+     cuda file to Visual Studio it knows that this file produces an object file
+     and will link in the resulting object file automatically.
+
+     This script will also generate a separate cmake script that is used at
+     build time to invoke nvcc.  This is for several reasons.
+
+       1. nvcc can return negative numbers as return values which confuses
+       Visual Studio into thinking that the command succeeded.  The script now
+       checks the error codes and produces errors when there was a problem.
+
+       2. nvcc has been known to not delete incomplete results when it
+       encounters problems.  This confuses build systems into thinking the
+       target was generated when in fact an unusable file exists.  The script
+       now deletes the output files if there was an error.
+
+       3. By putting all the options that affect the build into a file and then
+       make the build rule dependent on the file, the output files will be
+       regenerated when the options change.
+
+     This script also looks at optional arguments STATIC, SHARED, or MODULE to
+     determine when to target the object compilation for a shared library.
+     BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
+     CUDA_ADD_LIBRARY.  On some systems special flags are added for building
+     objects intended for shared libraries.  A preprocessor macro,
+     <target_name>_EXPORTS is defined when a shared library compilation is
+     detected.
+
+     Flags passed into add_definitions with -D or /D are passed along to nvcc.
+
+
+
+The script defines the following variables::
+
+  CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
+  CUDA_VERSION_MINOR    -- The minor version.
+  CUDA_VERSION
+  CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR
+  CUDA_HAS_FP16         -- Whether a short float (float16,fp16) is supported.
+
+  CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
+  CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
+                           SDK.  This script will not directly support finding
+                           specific libraries or headers, as that isn't
+                           supported by NVIDIA.  If you want to change
+                           libraries when the path changes see the
+                           FindCUDA.cmake script for an example of how to clear
+                           these variables.  There are also examples of how to
+                           use the CUDA_SDK_ROOT_DIR to locate headers or
+                           libraries, if you so choose (at your own risk).
+  CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
+                           for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
+  CUDA_LIBRARIES        -- Cuda RT library.
+  CUDA_CUFFT_LIBRARIES  -- Device or emulation library for the Cuda FFT
+                           implementation (alternative to:

+There are situations where it may be undesirable for a particular config option

+``GIF::GIF``
+  The ``giflib`` library, if found.
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``GIF_FOUND``
+  If false, do not try to use GIF.
+``GIF_INCLUDE_DIRS``
+  where to find gif_lib.h, etc.

+  the libraries needed to use GIF.
+``GIF_VERSION``
+  3, 4 or a full version string (eg 5.1.4) for versions >= 4.1.6.
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``GIF_INCLUDE_DIR``
+  where to find the GIF headers.
+``GIF_LIBRARY``
+  where to find the GIF library.
+
+Hints
+^^^^^
+
+``GIF_DIR`` is an environment variable that would correspond to the
+``./configure --prefix=$GIF_DIR``.

-# FindHDF5
-# --------
-#
-# Find HDF5, a library for reading and writing self describing array data.
-#
-#
-#
-# This module invokes the HDF5 wrapper compiler that should be installed
-# alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper
-# compiler is called either h5cc or h5pcc.  If this succeeds, the module
-# will then call the compiler with the -show argument to see what flags
-# are used when compiling an HDF5 client application.
-#
-# The module will optionally accept the COMPONENTS argument.  If no
-# COMPONENTS are specified, then the find module will default to finding
-# only the HDF5 C library.  If one or more COMPONENTS are specified, the
-# module will attempt to find the language bindings for the specified
-# components.  The only valid components are C, CXX, Fortran, HL, and
-# Fortran_HL.  If the COMPONENTS argument is not given, the module will
-# attempt to find only the C bindings.
-#
-# On UNIX systems, this module will read the variable
-# HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
-# static link to a dynamic link for HDF5 and all of it's dependencies.
-# To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
-# variable is set before the call to find_package.
-#
-# To provide the module with a hint about where to find your HDF5
-# installation, you can set the environment variable HDF5_ROOT.  The
-# Find module will then look in this path when searching for HDF5
-# executables, paths, and libraries.
-#
-# Both the serial and parallel HDF5 wrappers are considered and the first
-# directory to contain either one will be used.  In the event that both appear
-# in the same directory the serial version is preferentially selected. This
-# behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to
-# true.
-#
-# In addition to finding the includes and libraries required to compile
-# an HDF5 client application, this module also makes an effort to find
-# tools that come with the HDF5 distribution that may be useful for
-# regression testing.
-#
-# This module will define the following variables:
-#
-# ::
-#
-#   HDF5_FOUND - true if HDF5 was found on the system
-#   HDF5_VERSION - HDF5 version in format Major.Minor.Release
-#   HDF5_INCLUDE_DIRS - Location of the hdf5 includes
-#   HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
-#   HDF5_DEFINITIONS - Required compiler definitions for HDF5
-#   HDF5_LIBRARIES - Required libraries for all requested bindings
-#   HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API for all
-#                       bindings, if the HL component is enabled
-#
-# Available components are: C CXX Fortran and HL.  For each enabled language
-# binding, a corresponding HDF5_${LANG}_LIBRARIES variable, and potentially
-# HDF5_${LANG}_DEFINITIONS, will be defined.
-# If the HL component is enabled, then an HDF5_${LANG}_HL_LIBRARIES will
-# also be defined.  With all components enabled, the following variables will be defined:
-#
-# ::
-#
-#   HDF5_C_DEFINITIONS -- Required compiler definitions for HDF5 C bindings
-#   HDF5_CXX_DEFINITIONS -- Required compiler definitions for HDF5 C++ bindings
-#   HDF5_Fortran_DEFINITIONS -- Required compiler definitions for HDF5 Fortran bindings
-#   HDF5_C_INCLUDE_DIRS -- Required include directories for HDF5 C bindings
-#   HDF5_CXX_INCLUDE_DIRS -- Required include directories for HDF5 C++ bindings
-#   HDF5_Fortran_INCLUDE_DIRS -- Required include directories for HDF5 Fortran bindings
-#   HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings
-#   HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
-#   HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings
-#   HDF5_C_HL_LIBRARIES - Required libraries for the high level C bindings
-#   HDF5_CXX_HL_LIBRARIES - Required libraries for the high level C++ bindings
-#   HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
-#                               bindings.
-#
-#   HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
-#   HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
-#   HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
-#   HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler

-#                                               which is also the HDF5 wrapper

+FindHDF5
+--------
+
+Find Hierarchical Data Format (HDF5), a library for reading and writing
+self describing array data.
+
+
+This module invokes the ``HDF5`` wrapper compiler that should be installed
+alongside ``HDF5``.  Depending upon the ``HDF5`` Configuration, the wrapper
+compiler is called either ``h5cc`` or ``h5pcc``.  If this succeeds, the module
+will then call the compiler with the show argument to see what flags
+are used when compiling an ``HDF5`` client application.
+
+The module will optionally accept the ``COMPONENTS`` argument.  If no
+``COMPONENTS`` are specified, then the find module will default to finding
+only the ``HDF5`` C library.  If one or more ``COMPONENTS`` are specified, the
+module will attempt to find the language bindings for the specified
+components.  The only valid components are ``C``, ``CXX``, ``Fortran``, ``HL``,
+and ``Fortran_HL``.  If the ``COMPONENTS`` argument is not given, the module will
+attempt to find only the C bindings.
+
+This module will read the variable
+``HDF5_USE_STATIC_LIBRARIES`` to determine whether or not to prefer a
+static link to a dynamic link for ``HDF5`` and all of it's dependencies.
+To use this feature, make sure that the ``HDF5_USE_STATIC_LIBRARIES``
+variable is set before the call to find_package.
+
+To provide the module with a hint about where to find your ``HDF5``
+installation, you can set the environment variable ``HDF5_ROOT``.  The
+Find module will then look in this path when searching for ``HDF5``
+executables, paths, and libraries.
+
+Both the serial and parallel ``HDF5`` wrappers are considered and the first
+directory to contain either one will be used.  In the event that both appear
+in the same directory the serial version is preferentially selected. This
+behavior can be reversed by setting the variable ``HDF5_PREFER_PARALLEL`` to
+``True``.
+
+In addition to finding the includes and libraries required to compile
+an ``HDF5`` client application, this module also makes an effort to find
+tools that come with the ``HDF5`` distribution that may be useful for
+regression testing.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``HDF5_FOUND``
+  HDF5 was found on the system
+``HDF5_VERSION``
+  HDF5 library version
+``HDF5_INCLUDE_DIRS``
+  Location of the HDF5 header files
+``HDF5_DEFINITIONS``
+  Required compiler definitions for HDF5
+``HDF5_LIBRARIES``
+  Required libraries for all requested bindings
+``HDF5_HL_LIBRARIES``
+  Required libraries for the HDF5 high level API for all bindings,
+  if the ``HL`` component is enabled
+
+Available components are: ``C`` ``CXX`` ``Fortran`` and ``HL``.
+For each enabled language binding, a corresponding ``HDF5_${LANG}_LIBRARIES``
+variable, and potentially ``HDF5_${LANG}_DEFINITIONS``, will be defined.
+If the ``HL`` component is enabled, then an ``HDF5_${LANG}_HL_LIBRARIES`` will
+also be defined.  With all components enabled, the following variables will be defined:
+
+``HDF5_C_DEFINITIONS``
+  Required compiler definitions for HDF5 C bindings
+``HDF5_CXX_DEFINITIONS``
+  Required compiler definitions for HDF5 C++ bindings
+``HDF5_Fortran_DEFINITIONS``

+  Required include directories for HDF5 Fortran bindings
+``HDF5_C_LIBRARIES``
+  Required libraries for the HDF5 C bindings
+``HDF5_CXX_LIBRARIES``
+  Required libraries for the HDF5 C++ bindings
+``HDF5_Fortran_LIBRARIES``
+  Required libraries for the HDF5 Fortran bindings
+``HDF5_C_HL_LIBRARIES``
+  Required libraries for the high level C bindings
+``HDF5_CXX_HL_LIBRARIES``
+  Required libraries for the high level C++ bindings
+``HDF5_Fortran_HL_LIBRARIES``
+  Required libraries for the high level Fortran bindings.
+
+``HDF5_IS_PARALLEL``
+  HDF5 library has parallel IO support
+``HDF5_C_COMPILER_EXECUTABLE``
+  path to the HDF5 C wrapper compiler
+``HDF5_CXX_COMPILER_EXECUTABLE``
+  path to the HDF5 C++ wrapper compiler
+``HDF5_Fortran_COMPILER_EXECUTABLE``
+  path to the HDF5 Fortran wrapper compiler
+``HDF5_C_COMPILER_EXECUTABLE_NO_INTERROGATE``
+  path to the primary C compiler which is also the HDF5 wrapper
+``HDF5_CXX_COMPILER_EXECUTABLE_NO_INTERROGATE``
+  path to the primary C++ compiler which is also the HDF5 wrapper
+``HDF5_Fortran_COMPILER_EXECUTABLE_NO_INTERROGATE``
+  path to the primary Fortran compiler which is also the HDF5 wrapper
+``HDF5_DIFF_EXECUTABLE``
+  path to the HDF5 dataset comparison tool
+
+Hints
+^^^^^
+
+The following variable can be set to guide the search for HDF5 libraries and includes:
+
+``HDF5_ROOT``
+  Specify the path to the HDF5 installation to use.
+
+``HDF5_FIND_DEBUG``
+  Set ``true`` to get extra debugging output.
+
+``HDF5_NO_FIND_PACKAGE_CONFIG_FILE``
+  Set ``true`` to skip trying to find ``hdf5-config.cmake``.

+
+Find Java Native Interface (JNI) libraries.
+
+JNI enables Java code running in a Java Virtual Machine (JVM) to call
+and be called by native applications and libraries written in other
+languages such as C, C++.
+
+This module finds if Java is installed and determines where the
+include files and libraries are.  It also determines what the name of
+the library is.  The caller may set variable ``JAVA_HOME`` to specify a
+Java installation prefix explicitly.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module sets the following result variables:
+
+``JNI_INCLUDE_DIRS``
+  the include dirs to use
+``JNI_LIBRARIES``
+  the libraries to use (JAWT and JVM)
+``JNI_FOUND``
+  TRUE if JNI headers and libraries were found.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables are also available to set or use:
+
+``JAVA_AWT_LIBRARY``
+  the path to the Java AWT Native Interface (JAWT) library
+``JAVA_JVM_LIBRARY``
+  the path to the Java Virtual Machine (JVM) library

-#
-# The following user adjustable options are provided:
-#
-# ``KDE3_BUILD_TESTS``
-#   enable this to build KDE testcases
-#
-# It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is
-# always the variable which contains the list of source files for your
-# application or library.
-#
-# KDE3_AUTOMOC(file1 ...  fileN)
-#
-# ::
-#
-#     Call this if you want to have automatic moc file handling.
-#     This means if you include "foo.moc" in the source file foo.cpp
-#     a moc file for the header foo.h will be created automatically.
-#     You can set the property SKIP_AUTOMAKE using set_source_files_properties()
-#     to exclude some files in the list from being processed.
-#
-#
-#
-# KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )
-#
-# ::
-#
-#     If you don't use the KDE3_AUTOMOC() macro, for the files
-#     listed here moc files will be created (named "foo.moc.cpp")
-#
-#
-#
-# KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )
-#
-# ::
-#
-#     Use this to generate DCOP skeletions from the listed headers.
-#
-#
-#
-# KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )
-#
-# ::
-#
-#      Use this to generate DCOP stubs from the listed headers.
-#
-#
-#
-# KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )
-#
-# ::
-#
-#     Use this to add the Qt designer ui files to your application/library.
-#
-#
-#
-# KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )
-#
-# ::
-#
-#     Use this to add KDE kconfig compiler files to your application/library.
-#
-#
-#
-# KDE3_INSTALL_LIBTOOL_FILE(target)
-#
-# ::
-#
-#     This will create and install a simple libtool file for the given target.
-#
-#
-#
-# KDE3_ADD_EXECUTABLE(name file1 ...  fileN )
-#
-# ::
-#
-#     Currently identical to add_executable(), may provide some advanced
-#     features in the future.
-#
-#
-#
-# KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )
-#
-# ::
-#
-#     Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
-#     If WITH_PREFIX is given, the resulting plugin will have the prefix "lib",
-#     otherwise it won't.
-#     It creates and installs an appropriate libtool la-file.
-#
-#
-#
-# KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )
-#
-# ::

+FindKDE3
+--------
+
+Find the KDE3 include and library dirs, KDE preprocessors and define a some macros
+
+
+
+This module defines the following variables:
+
+``KDE3_DEFINITIONS``
+  compiler definitions required for compiling KDE software
+``KDE3_INCLUDE_DIR``
+  the KDE include directory
+``KDE3_INCLUDE_DIRS``
+  the KDE and the Qt include directory, for use with include_directories()
+``KDE3_LIB_DIR``
+  the directory where the KDE libraries are installed, for use with link_directories()
+``QT_AND_KDECORE_LIBS``
+  this contains both the Qt and the kdecore library
+``KDE3_DCOPIDL_EXECUTABLE``
+  the dcopidl executable
+``KDE3_DCOPIDL2CPP_EXECUTABLE``
+  the dcopidl2cpp executable
+``KDE3_KCFGC_EXECUTABLE``
+  the kconfig_compiler executable
+``KDE3_FOUND``
+  set to TRUE if all of the above has been found
+
+The following user adjustable options are provided:
+
+``KDE3_BUILD_TESTS``
+  enable this to build KDE testcases
+
+It also adds the following macros (from ``KDE3Macros.cmake``) ``SRCS_VAR`` is
+always the variable which contains the list of source files for your
+application or library.
+
+KDE3_AUTOMOC(file1 ...  fileN)
+
+::
+
+    Call this if you want to have automatic moc file handling.
+    This means if you include "foo.moc" in the source file foo.cpp
+    a moc file for the header foo.h will be created automatically.
+    You can set the property SKIP_AUTOMAKE using set_source_files_properties()
+    to exclude some files in the list from being processed.
+
+
+
+KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )
+
+::
+
+    If you don't use the KDE3_AUTOMOC() macro, for the files
+    listed here moc files will be created (named "foo.moc.cpp")
+
+
+
+KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )
+
+::
+
+    Use this to generate DCOP skeletions from the listed headers.
+
+
+
+KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )
+
+::
+
+     Use this to generate DCOP stubs from the listed headers.
+
+
+
+KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )
+
+::
+
+    Use this to add the Qt designer ui files to your application/library.
+
+
+
+KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )
+
+::
+
+    Use this to add KDE kconfig compiler files to your application/library.
+
+
+
+KDE3_INSTALL_LIBTOOL_FILE(target)
+
+::
+
+    This will create and install a simple libtool file for the given target.
+
+
+
+KDE3_ADD_EXECUTABLE(name file1 ...  fileN )
+
+::
+
+    Currently identical to add_executable(), may provide some advanced
+    features in the future.
+
+
+
+KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )
+
+::
+
+    Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
+    If WITH_PREFIX is given, the resulting plugin will have the prefix "lib",
+    otherwise it won't.
+    It creates and installs an appropriate libtool la-file.
+
+
+
+KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )
+
+::
+
+    Create a KDE application in the form of a module loadable via kdeinit.
+    A library named kdeinit_<name> will be created and a small executable
+    which links to it.
+
+
+
+The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no
+longer supported.

+Find Linear Algebra PACKage (LAPACK) library
+
+This module finds an installed fortran library that implements the
+LAPACK linear-algebra interface (see http://www.netlib.org/lapack/).
+
+The approach follows that taken for the autoconf macro file,
+``acx_lapack.m4`` (distributed at
+http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html).
+
+Input Variables
+^^^^^^^^^^^^^^^
+
+The following variables may be set to influence this module's behavior:
+
+``BLA_STATIC``
+  if ``ON`` use static linkage
+
+``BLA_VENDOR``
+  If set, checks only the specified vendor, if not set checks all the
+  possibilities.  List of vendors valid in this module:
+
+  * ``Intel10_32`` (intel mkl v10 32 bit)
+  * ``Intel10_64lp`` (intel mkl v10+ 64 bit, threaded code, lp64 model)
+  * ``Intel10_64lp_seq`` (intel mkl v10+ 64 bit, sequential code, lp64 model)
+  * ``Intel10_64ilp`` (intel mkl v10+ 64 bit, threaded code, ilp64 model)
+  * ``Intel10_64ilp_seq`` (intel mkl v10+ 64 bit, sequential code, ilp64 model)
+  * ``Intel`` (obsolete versions of mkl 32 and 64 bit)
+  * ``OpenBLAS``
+  * ``FLAME``
+  * ``ACML``
+  * ``Apple``
+  * ``NAS``
+  * ``Generic``
+
+``BLA_F95``
+  if ``ON`` tries to find BLAS95/LAPACK95
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+``LAPACK_FOUND``
+  library implementing the LAPACK interface is found
+``LAPACK_LINKER_FLAGS``
+  uncached list of required linker flags (excluding -l and -L).
+``LAPACK_LIBRARIES``
+  uncached list of libraries (using full path name) to link against
+  to use LAPACK
+``LAPACK95_LIBRARIES``

-# Usage
-# ^^^^^
-#
-# To use this module, call ``find_package(MPI)``.  If you are happy with the
-# auto-detected configuration for your language, then you're done.  If
-# not, you have two options:
-#
-# 1. Set ``MPI_<lang>_COMPILER`` to the MPI wrapper (e.g. ``mpicc``) of your
-#    choice and reconfigure.  FindMPI will attempt to determine all the
-#    necessary variables using *that* compiler's compile and link flags.
-# 2. If this fails, or if your MPI implementation does not come with
-#    a compiler wrapper, then set both ``MPI_<lang>_LIBRARIES`` and
-#    ``MPI_<lang>_INCLUDE_PATH``.  You may also set any other variables
-#    listed above, but these two are required.  This will circumvent
-#    autodetection entirely.
-#
-# When configuration is successful, ``MPI_<lang>_COMPILER`` will be set to
-# the compiler wrapper for ``<lang>``, if it was found. ``MPI_<lang>_FOUND``
-# and other variables above will be set if any MPI implementation was
-# found for ``<lang>``, regardless of whether a compiler was found.
-#
-# When using ``MPIEXEC`` to execute MPI applications, you should typically
-# use all of the ``MPIEXEC`` flags as follows:
-#
-# ::
-#
-#    ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS}
-#      ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
-#
-# where ``EXECUTABLE`` is the MPI program, and ``ARGS`` are the arguments to
-# pass to the MPI program.
-#
-# Backward Compatibility
-# ^^^^^^^^^^^^^^^^^^^^^^
-#
-# For backward compatibility with older versions of FindMPI, these
-# variables are set, but deprecated:
-#
-# ::
-#
-#    MPI_FOUND           MPI_COMPILER        MPI_LIBRARY
-#    MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
-#    MPI_LINK_FLAGS      MPI_LIBRARIES
-#
-# In new projects, please use the ``MPI_<lang>_XXX`` equivalents.

+FindMPI
+-------
+
+Find a Message Passing Interface (MPI) implementation.
+
+The Message Passing Interface (MPI) is a library used to write
+high-performance distributed-memory parallel applications, and is
+typically deployed on a cluster.  MPI is a standard interface (defined
+by the MPI forum) for which many implementations are available.
+
+Variables for using MPI
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The module exposes the components ``C``, ``CXX``, ``MPICXX`` and ``Fortran``.
+Each of these controls the various MPI languages to search for.
+The difference between ``CXX`` and ``MPICXX`` is that ``CXX`` refers to the
+MPI C API being usable from C++, whereas ``MPICXX`` refers to the MPI-2 C++ API
+that was removed again in MPI-3.
+
+Depending on the enabled components the following variables will be set:
+
+``MPI_FOUND``
+  Variable indicating that MPI settings for all requested languages have been found.
+  If no components are specified, this is true if MPI settings for all enabled languages
+  were detected. Note that the ``MPICXX`` component does not affect this variable.
+``MPI_VERSION``
+  Minimal version of MPI detected among the requested languages, or all enabled languages
+  if no components were specified.
+
+This module will set the following variables per language in your
+project, where ``<lang>`` is one of C, CXX, or Fortran:
+
+``MPI_<lang>_FOUND``
+  Variable indicating the MPI settings for ``<lang>`` were found and that
+  simple MPI test programs compile with the provided settings.
+``MPI_<lang>_COMPILER``
+  MPI compiler for ``<lang>`` if such a program exists.
+``MPI_<lang>_COMPILE_OPTIONS``
+  Compilation options for MPI programs in ``<lang>``, given as a :ref:`;-list <CMake Language Lists>`.
+``MPI_<lang>_COMPILE_DEFINITIONS``
+  Compilation definitions for MPI programs in ``<lang>``, given as a :ref:`;-list <CMake Language Lists>`.
+``MPI_<lang>_INCLUDE_DIRS``
+  Include path(s) for MPI header.
+``MPI_<lang>_LINK_FLAGS``
+  Linker flags for MPI programs.
+``MPI_<lang>_LIBRARIES``
+  All libraries to link MPI programs against.
+
+Additionally, the following :prop_tgt:`IMPORTED` targets are defined:
+
+``MPI::MPI_<lang>``
+  Target for using MPI from ``<lang>``.
+
+The following variables indicating which bindings are present will be defined:
+
+``MPI_MPICXX_FOUND``
+  Variable indicating whether the MPI-2 C++ bindings are present (introduced in MPI-2, removed with MPI-3).
+``MPI_Fortran_HAVE_F77_HEADER``
+  True if the Fortran 77 header ``mpif.h`` is available.
+``MPI_Fortran_HAVE_F90_MODULE``
+  True if the Fortran 90 module ``mpi`` can be used for accessing MPI (MPI-2 and higher only).
+``MPI_Fortran_HAVE_F08_MODULE``
+  True if the Fortran 2008 ``mpi_f08`` is available to MPI programs (MPI-3 and higher only).
+
+If possible, the MPI version will be determined by this module. The facilities to detect the MPI version
+were introduced with MPI-1.2, and therefore cannot be found for older MPI versions.
+
+``MPI_<lang>_VERSION_MAJOR``
+  Major version of MPI implemented for ``<lang>`` by the MPI distribution.
+``MPI_<lang>_VERSION_MINOR``
+  Minor version of MPI implemented for ``<lang>`` by the MPI distribution.
+``MPI_<lang>_VERSION``
+  MPI version implemented for ``<lang>`` by the MPI distribution.
+
+Note that there's no variable for the C bindings being accessible through ``mpi.h``, since the MPI standards
+always have required this binding to work in both C and C++ code.
+
+For running MPI programs, the module sets the following variables
+
+``MPIEXEC_EXECUTABLE``
+  Executable for running MPI programs, if such exists.
+``MPIEXEC_NUMPROC_FLAG``
+  Flag to pass to ``mpiexec`` before giving it the number of processors to run on.
+``MPIEXEC_MAX_NUMPROCS``
+  Number of MPI processors to utilize. Defaults to the number
+  of processors detected on the host system.
+``MPIEXEC_PREFLAGS``
+  Flags to pass to ``mpiexec`` directly before the executable to run.
+``MPIEXEC_POSTFLAGS``
+  Flags to pass to ``mpiexec`` after other flags.
+
+Variables for locating MPI
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This module performs a three step search for an MPI implementation:
+
+1. Check if the compiler has MPI support built-in. This is the case if the user passed a
+   compiler wrapper as ``CMAKE_<LANG>_COMPILER`` or if they're on a Cray system.
+2. Attempt to find an MPI compiler wrapper and determine the compiler information from it.
+3. Try to find an MPI implementation that does not ship such a wrapper by guessing settings.
+   Currently, only Microsoft MPI and MPICH2 on Windows are supported.
+
+For controlling the second step, the following variables may be set:
+
+``MPI_<lang>_COMPILER``
+  Search for the specified compiler wrapper and use it.
+``MPI_<lang>_COMPILER_FLAGS``
+  Flags to pass to the MPI compiler wrapper during interrogation. Some compiler wrappers
+  support linking debug or tracing libraries if a specific flag is passed and this variable
+  may be used to obtain them.
+``MPI_COMPILER_FLAGS``
+  Used to initialize ``MPI_<lang>_COMPILER_FLAGS`` if no language specific flag has been given.
+  Empty by default.
+``MPI_EXECUTABLE_SUFFIX``
+  A suffix which is appended to all names that are being looked for. For instance you may set this
+  to ``.mpich`` or ``.openmpi`` to prefer the one or the other on Debian and its derivatives.
+
+In order to control the guessing step, the following variable may be set:
+
+``MPI_GUESS_LIBRARY_NAME``
+  Valid values are ``MSMPI`` and ``MPICH2``. If set, only the given library will be searched for.
+  By default, ``MSMPI`` will be preferred over ``MPICH2`` if both are available.
+  This also sets ``MPI_SKIP_COMPILER_WRAPPER`` to ``true``, which may be overridden.
+
+Each of the search steps may be skipped with the following control variables:
+
+``MPI_ASSUME_NO_BUILTIN_MPI``
+  If true, the module assumes that the compiler itself does not provide an MPI implementation and
+  skips to step 2.
+``MPI_SKIP_COMPILER_WRAPPER``
+  If true, no compiler wrapper will be searched for.
+``MPI_SKIP_GUESSING``
+  If true, the guessing step will be skipped.
+
+Additionally, the following control variable is available to change search behavior:
+
+``MPI_CXX_SKIP_MPICXX``
+  Add some definitions that will disable the MPI-2 C++ bindings.
+  Currently supported are MPICH, Open MPI, Platform MPI and derivatives thereof,
+  for example MVAPICH or Intel MPI.
+
+If the find procedure fails for a variable ``MPI_<lang>_WORKS``, then the settings detected by or passed to
+the module did not work and even a simple MPI test program failed to compile.
+
+If all of these parameters were not sufficient to find the right MPI implementation, a user may
+disable the entire autodetection process by specifying both a list of libraries in ``MPI_<lang>_LIBRARIES``
+and a list of include directories in ``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS``.
+Any other variable may be set in addition to these two. The module will then validate the MPI settings and store the
+settings in the cache.
+
+Cache variables for MPI
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The variable ``MPI_<lang>_INCLUDE_DIRS`` will be assembled from the following variables.
+For C and CXX:
+
+``MPI_<lang>_HEADER_DIR``
+  Location of the ``mpi.h`` header on disk.
+
+For Fortran:
+
+``MPI_Fortran_F77_HEADER_DIR``
+  Location of the Fortran 77 header ``mpif.h``, if it exists.
+``MPI_Fortran_MODULE_DIR``
+  Location of the ``mpi`` or ``mpi_f08`` modules, if available.
+
+For all languages the following variables are additionally considered:
+
+``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS``
+  A :ref:`;-list <CMake Language Lists>` of paths needed in addition to the normal include directories.
+``MPI_<include_name>_INCLUDE_DIR``
+  Path variables for include folders referred to by ``<include_name>``.
+``MPI_<lang>_ADDITIONAL_INCLUDE_VARS``
+  A :ref:`;-list <CMake Language Lists>` of ``<include_name>`` that will be added to the include locations of ``<lang>``.
 
-include(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake)
+The variable ``MPI_<lang>_LIBRARIES`` will be assembled from the following variables:
 
-#
-# This part detects MPI compilers, attempting to wade through the mess of compiler names in
-# a sensible way.
-#
-# The compilers are detected in this order:
-#
-# 1. Try to find the most generic available MPI compiler, as this is usually set up by
-#    cluster admins, e.g. if plain old mpicc is available, we'll use it and assume it's
-#    the right compiler.
-#
-# 2. If a generic mpicc is NOT found, then we attempt to find one that matches
-#    CMAKE_<lang>_COMPILER_ID. e.g. if you are using XL compilers, we'll try to find mpixlc
-#    and company, but not mpiicc. This hopefully prevents toolchain mismatches.
-#
-# If you want to force a particular MPI compiler other than what we autodetect (e.g. if you
-# want to compile regular stuff with GNU and parallel stuff with Intel), you can always set
-# your favorite MPI_<lang>_COMPILER explicitly and this stuff will be ignored.
-#
+``MPI_<lib_name>_LIBRARY``
+  The location of a library called ``<lib_name>`` for use with MPI.
+``MPI_<lang>_LIB_NAMES``
+  A :ref:`;-list <CMake Language Lists>` of ``<lib_name>`` that will be added to the include locations of ``<lang>``.
+
+Usage of mpiexec
+^^^^^^^^^^^^^^^^
+
+When using ``MPIEXEC_EXECUTABLE`` to execute MPI applications, you should typically
+use all of the ``MPIEXEC_EXECUTABLE`` flags as follows:
+
+::
+
+   ${MPIEXEC_EXECUTABLE} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS}
+     ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
+
+where ``EXECUTABLE`` is the MPI program, and ``ARGS`` are the arguments to
+pass to the MPI program.
+
+Advanced variables for using MPI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The module can perform some advanced feature detections upon explicit request.
+
+**Important notice:** The following checks cannot be performed without *executing* an MPI test program.
+Consider the special considerations for the behavior of :command:`try_run` during cross compilation.
+Moreover, running an MPI program can cause additional issues, like a firewall notification on some systems.
+You should only enable these detections if you absolutely need the information.
+
+If the following variables are set to true, the respective search will be performed:
+
+``MPI_DETERMINE_Fortran_CAPABILITIES``
+  Determine for all available Fortran bindings what the values of ``MPI_SUBARRAYS_SUPPORTED`` and
+  ``MPI_ASYNC_PROTECTS_NONBLOCKING`` are and make their values available as ``MPI_Fortran_<binding>_SUBARRAYS``
+  and ``MPI_Fortran_<binding>_ASYNCPROT``, where ``<binding>`` is one of ``F77_HEADER``, ``F90_MODULE`` and
+  ``F08_MODULE``.
+``MPI_DETERMINE_LIBRARY_VERSION``
+  For each language, find the output of ``MPI_Get_library_version`` and make it available as ``MPI_<lang>_LIBRARY_VERSION_STRING``.
+  This information is usually tied to the runtime component of an MPI implementation and might differ depending on ``<lang>``.
+  Note that the return value is entirely implementation defined. This information might be used to identify
+  the MPI vendor and for example pick the correct one of multiple third party binaries that matches the MPI vendor.
+

+
+In new projects, please use the ``MPI_<lang>_XXX`` equivalents.
+Additionally, the following variables are deprecated:
+
+``MPI_<lang>_COMPILE_FLAGS``
+  Use ``MPI_<lang>_COMPILE_OPTIONS`` and ``MPI_<lang>_COMPILE_DEFINITIONS`` instead.
+``MPI_<lang>_INCLUDE_PATH``
+  For consumption use ``MPI_<lang>_INCLUDE_DIRS`` and for specifying folders use ``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS`` instead.

-# FindMatlab
-# ----------
-#
-# Finds Matlab installations and provides Matlab tools and libraries to cmake.
-#
-# This package first intention is to find the libraries associated with Matlab
-# in order to be able to build Matlab extensions (mex files). It can also be
-# used:
-#
-# * run specific commands in Matlab
-# * declare Matlab unit test
-# * retrieve various information from Matlab (mex extensions, versions and
-#   release queries, ...)
-#
-# The module supports the following components:
-#
-# * ``MX_LIBRARY``, ``ENG_LIBRARY`` and ``MAT_LIBRARY``: respectively the MX,
-#   ENG and MAT libraries of Matlab
-# * ``MAIN_PROGRAM`` the Matlab binary program.
-# * ``MEX_COMPILER`` the MEX compiler.
-# * ``SIMULINK`` the Simulink environment.
-#
-# .. note::
-#
-#   The version given to the :command:`find_package` directive is the Matlab
-#   **version**, which should not be confused with the Matlab *release* name
-#   (eg. `R2014`).
-#   The :command:`matlab_get_version_from_release_name` and
-#   :command:`matlab_get_release_name_from_version` allow a mapping
-#   from the release name to the version.
-#
-# The variable :variable:`Matlab_ROOT_DIR` may be specified in order to give
-# the path of the desired Matlab version. Otherwise, the behaviour is platform
-# specific:
-#
-# * Windows: The installed versions of Matlab are retrieved from the
-#   Windows registry
-# * OS X: The installed versions of Matlab are given by the MATLAB
-#   paths in ``/Application``. If no such application is found, it falls back
-#   to the one that might be accessible from the PATH.
-# * Unix: The desired Matlab should be accessible from the PATH.
-#
-# Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set.
-# When a Matlab binary is found automatically and the ``MATLAB_VERSION``
-# is not given, the version is queried from Matlab directly.
-# On Windows, it can make a window running Matlab appear.
-#
-# The mapping of the release names and the version of Matlab is performed by
-# defining pairs (name, version).  The variable
-# :variable:`MATLAB_ADDITIONAL_VERSIONS` may be provided before the call to
-# the :command:`find_package` in order to handle additional versions.
-#
-# A Matlab scripts can be added to the set of tests using the
-# :command:`matlab_add_unit_test`. By default, the Matlab unit test framework
-# will be used (>= 2013a) to run this script, but regular ``.m`` files
-# returning an exit code can be used as well (0 indicating a success).
-#
-# Module Input Variables
-# ^^^^^^^^^^^^^^^^^^^^^^
-#
-# Users or projects may set the following variables to configure the module
-# behaviour:
-#
-# :variable:`Matlab_ROOT_DIR`
-#   the root of the Matlab installation.
-# :variable:`MATLAB_FIND_DEBUG`
-#   outputs debug information
-# :variable:`MATLAB_ADDITIONAL_VERSIONS`
-#   additional versions of Matlab for the automatic retrieval of the installed
-#   versions.
-#
-# Variables defined by the module
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# Result variables
-# """"""""""""""""
-#
-# ``Matlab_FOUND``
-#   ``TRUE`` if the Matlab installation is found, ``FALSE``
-#   otherwise. All variable below are defined if Matlab is found.
-# ``Matlab_ROOT_DIR``
-#   the final root of the Matlab installation determined by the FindMatlab
-#   module.
-# ``Matlab_MAIN_PROGRAM``
-#   the Matlab binary program. Available only if the component ``MAIN_PROGRAM``
-#   is given in the :command:`find_package` directive.
-# ``Matlab_INCLUDE_DIRS``
-#  the path of the Matlab libraries headers
-# ``Matlab_MEX_LIBRARY``
-#   library for mex, always available.
-# ``Matlab_MX_LIBRARY``
-#   mx library of Matlab (arrays). Available only if the component
-#   ``MX_LIBRARY`` has been requested.
-# ``Matlab_ENG_LIBRARY``
-#   Matlab engine library. Available only if the component ``ENG_LIBRARY``
-#   is requested.
-# ``Matlab_MAT_LIBRARY``
-#   Matlab matrix library. Available only if the component ``MAT_LIBRARY``
-#   is requested.
-# ``Matlab_LIBRARIES``
-#   the whole set of libraries of Matlab
-# ``Matlab_MEX_COMPILER``
-#   the mex compiler of Matlab. Currently not used.
-#   Available only if the component ``MEX_COMPILER`` is asked
-#
-# Cached variables
-# """"""""""""""""
-#
-# ``Matlab_MEX_EXTENSION``
-#   the extension of the mex files for the current platform (given by Matlab).
-# ``Matlab_ROOT_DIR``
-#   the location of the root of the Matlab installation found. If this value
-#   is changed by the user, the result variables are recomputed.
-#
-# Provided macros
-# ^^^^^^^^^^^^^^^
-#
-# :command:`matlab_get_version_from_release_name`
-#   returns the version from the release name
-# :command:`matlab_get_release_name_from_version`
-#   returns the release name from the Matlab version
-#
-# Provided functions
-# ^^^^^^^^^^^^^^^^^^
-#
-# :command:`matlab_add_mex`
-#   adds a target compiling a MEX file.
-# :command:`matlab_add_unit_test`
-#   adds a Matlab unit test file as a test to the project.
-# :command:`matlab_extract_all_installed_versions_from_registry`
-#   parses the registry for all Matlab versions. Available on Windows only.
-#   The part of the registry parsed is dependent on the host processor
-# :command:`matlab_get_all_valid_matlab_roots_from_registry`
-#   returns all the possible Matlab paths, according to a previously
-#   given list. Only the existing/accessible paths are kept. This is mainly
-#   useful for the searching all possible Matlab installation.
-# :command:`matlab_get_mex_suffix`
-#   returns the suffix to be used for the mex files
-#   (platform/architecture dependent)
-# :command:`matlab_get_version_from_matlab_run`
-#   returns the version of Matlab, given the full directory of the Matlab
-#   program.
-#
-#
-# Known issues
-# ^^^^^^^^^^^^
-#
-# **Symbol clash in a MEX target**
-#   By default, every symbols inside a MEX
-#   file defined with the command :command:`matlab_add_mex` have hidden
-#   visibility, except for the entry point. This is the default behaviour of
-#   the MEX compiler, which lowers the risk of symbol collision between the
-#   libraries shipped with Matlab, and the libraries to which the MEX file is
-#   linking to. This is also the default on Windows platforms.
-#
-#   However, this is not sufficient in certain case, where for instance your
-#   MEX file is linking against libraries that are already loaded by Matlab,
-#   even if those libraries have different SONAMES.
-#   A possible solution is to hide the symbols of the libraries to which the
-#   MEX target is linking to. This can be achieved in GNU GCC compilers with
-#   the linker option ``-Wl,--exclude-libs,ALL``.
-#
-# **Tests using GPU resources**
-#   in case your MEX file is using the GPU and
-#   in order to be able to run unit tests on this MEX file, the GPU resources
-#   should be properly released by Matlab. A possible solution is to make
-#   Matlab aware of the use of the GPU resources in the session, which can be
-#   performed by a command such as ``D = gpuDevice()`` at the beginning of
-#   the test script (or via a fixture).
-#
-#
-# Reference
-# ^^^^^^^^^
-#
-# .. variable:: Matlab_ROOT_DIR
-#
-#    The root folder of the Matlab installation. If set before the call to
-#    :command:`find_package`, the module will look for the components in that
-#    path. If not set, then an automatic search of Matlab
-#    will be performed. If set, it should point to a valid version of Matlab.
-#
-# .. variable:: MATLAB_FIND_DEBUG
-#
-#    If set, the lookup of Matlab and the intermediate configuration steps are
-#    outputted to the console.
-#
-# .. variable:: MATLAB_ADDITIONAL_VERSIONS
-#
-#   If set, specifies additional versions of Matlab that may be looked for.
-#   The variable should be a list of strings, organised by pairs of release
-#   name and versions, such as follows::
-#
-#     set(MATLAB_ADDITIONAL_VERSIONS
-#         "release_name1=corresponding_version1"
-#         "release_name2=corresponding_version2"
-#         ...
-#         )
-#
-#   Example::
-#
-#     set(MATLAB_ADDITIONAL_VERSIONS
-#         "R2013b=8.2"
-#         "R2013a=8.1"
-#         "R2012b=8.0")
-#
-#   The order of entries in this list matters when several versions of
-#   Matlab are installed. The priority is set according to the ordering in
-#   this list.

+* to run specific commands in Matlab in case Matlab is available
+* for declaring Matlab unit test
+* to retrieve various information from Matlab (mex extensions, versions and
+  release queries, ...)
+
+The module supports the following components:
+
+* ``ENG_LIBRARY`` and ``MAT_LIBRARY``: respectively the ``ENG`` and ``MAT``
+  libraries of Matlab
+* ``MAIN_PROGRAM`` the Matlab binary program. Note that this component is not
+  available on the MCR version, and will yield an error if the MCR is found
+  instead of the regular Matlab installation.
+* ``MEX_COMPILER`` the MEX compiler.
+* ``MCC_COMPILER`` the MCC compiler, included with the Matlab Compiler add-on.
+* ``SIMULINK`` the Simulink environment.
+
+.. note::
+
+  The version given to the :command:`find_package` directive is the Matlab
+  **version**, which should not be confused with the Matlab *release* name
+  (eg. `R2014`).
+  The :command:`matlab_get_version_from_release_name` and
+  :command:`matlab_get_release_name_from_version` provide a mapping
+  between the release name and the version.
+
+The variable :variable:`Matlab_ROOT_DIR` may be specified in order to give
+the path of the desired Matlab version. Otherwise, the behaviour is platform
+specific:
+
+* Windows: The installed versions of Matlab/MCR are retrieved from the
+  Windows registry
+* OS X: The installed versions of Matlab/MCR are given by the MATLAB
+  default installation paths in ``/Application``. If no such application is
+  found, it falls back to the one that might be accessible from the ``PATH``.
+* Unix: The desired Matlab should be accessible from the ``PATH``. This does
+  not work for MCR installation and :variable:`Matlab_ROOT_DIR` should be
+  specified on this platform.
+
+Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set.
+When a Matlab/MCR installation is found automatically and the ``MATLAB_VERSION``
+is not given, the version is queried from Matlab directly (on Windows this
+may pop up a Matlab window) or from the MCR installation.
+
+The mapping of the release names and the version of Matlab is performed by
+defining pairs (name, version).  The variable
+:variable:`MATLAB_ADDITIONAL_VERSIONS` may be provided before the call to
+the :command:`find_package` in order to handle additional versions.
+
+A Matlab scripts can be added to the set of tests using the
+:command:`matlab_add_unit_test`. By default, the Matlab unit test framework
+will be used (>= 2013a) to run this script, but regular ``.m`` files
+returning an exit code can be used as well (0 indicating a success).

+
+Provided macros
+^^^^^^^^^^^^^^^
+
+:command:`matlab_get_version_from_release_name`
+  returns the version from the release name
+:command:`matlab_get_release_name_from_version`
+  returns the release name from the Matlab version
+
+Provided functions

+
+:command:`matlab_add_mex`
+  adds a target compiling a MEX file.
+:command:`matlab_add_unit_test`
+  adds a Matlab unit test file as a test to the project.

+  parses the registry for all Matlab versions. Available on Windows only.
+  The part of the registry parsed is dependent on the host processor
+:command:`matlab_get_all_valid_matlab_roots_from_registry`

+
+
+Known issues
+^^^^^^^^^^^^
+
+**Symbol clash in a MEX target**
+  By default, every symbols inside a MEX
+  file defined with the command :command:`matlab_add_mex` have hidden
+  visibility, except for the entry point. This is the default behaviour of
+  the MEX compiler, which lowers the risk of symbol collision between the
+  libraries shipped with Matlab, and the libraries to which the MEX file is
+  linking to. This is also the default on Windows platforms.
+
+  However, this is not sufficient in certain case, where for instance your
+  MEX file is linking against libraries that are already loaded by Matlab,
+  even if those libraries have different SONAMES.
+  A possible solution is to hide the symbols of the libraries to which the
+  MEX target is linking to. This can be achieved in GNU GCC compilers with
+  the linker option ``-Wl,--exclude-libs,ALL``.
+
+**Tests using GPU resources**
+  in case your MEX file is using the GPU and
+  in order to be able to run unit tests on this MEX file, the GPU resources
+  should be properly released by Matlab. A possible solution is to make
+  Matlab aware of the use of the GPU resources in the session, which can be
+  performed by a command such as ``D = gpuDevice()`` at the beginning of
+  the test script (or via a fixture).
+
+
+Reference
+^^^^^^^^^
+
+.. variable:: Matlab_ROOT_DIR
+
+   The root folder of the Matlab installation. If set before the call to
+   :command:`find_package`, the module will look for the components in that
+   path. If not set, then an automatic search of Matlab
+   will be performed. If set, it should point to a valid version of Matlab.
+
+.. variable:: MATLAB_FIND_DEBUG
+
+   If set, the lookup of Matlab and the intermediate configuration steps are
+   outputted to the console.
+
+.. variable:: MATLAB_ADDITIONAL_VERSIONS
+
+  If set, specifies additional versions of Matlab that may be looked for.
+  The variable should be a list of strings, organised by pairs of release
+  name and versions, such as follows::
+
+    set(MATLAB_ADDITIONAL_VERSIONS
+        "release_name1=corresponding_version1"
+        "release_name2=corresponding_version2"
+        ...
+        )
+
+  Example::
+
+    set(MATLAB_ADDITIONAL_VERSIONS
+        "R2013b=8.2"
+        "R2013a=8.1"
+        "R2012b=8.0")
+
+  The order of entries in this list matters when several versions of
+  Matlab are installed. The priority is set according to the ordering in
+  this list.

+FindModule for OpenGL and OpenGL Utility Library (GLU).
+
+Optional COMPONENTS
+^^^^^^^^^^^^^^^^^^^
+
+This module respects several optional COMPONENTS: ``EGL``, ``GLX``, and
+``OpenGL``.  There are corresponding import targets for each of these flags.
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+This module defines the :prop_tgt:`IMPORTED` targets:
+
+``OpenGL::GL``
+ Defined to the platform-specific OpenGL libraries if the system has OpenGL.
+``OpenGL::OpenGL``
+ Defined to libOpenGL if the system is GLVND-based.
+``OpenGL::GLU``
+ Defined if the system has OpenGL Utility Library (GLU).
+``OpenGL::GLX``
+ Defined if the system has OpenGL Extension to the X Window System (GLX).
+``OpenGL::EGL``
+ Defined if the system has EGL.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module sets the following variables:
+
+``OPENGL_FOUND``
+ True, if the system has OpenGL and all components are found.
+``OPENGL_XMESA_FOUND``
+ True, if the system has XMESA.
+``OPENGL_GLU_FOUND``
+ True, if the system has GLU.
+``OpenGL_OpenGL_FOUND``
+ True, if the system has an OpenGL library.
+``OpenGL_GLX_FOUND``
+ True, if the system has GLX.
+``OpenGL_EGL_FOUND``
+ True, if the system has EGL.
+``OPENGL_INCLUDE_DIR``
+ Path to the OpenGL include directory.
+``OPENGL_EGL_INCLUDE_DIRS``
+ Path to the EGL include directory.
+``OPENGL_LIBRARIES``
+ Paths to the OpenGL library, windowing system libraries, and GLU libraries.
+ On Linux, this assumes GLX and is never correct for EGL-based targets.
+ Clients are encouraged to use the ``OpenGL::*`` import targets instead.
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``OPENGL_egl_LIBRARY``
+ Path to the EGL library.
+``OPENGL_glu_LIBRARY``
+ Path to the GLU library.
+``OPENGL_glx_LIBRARY``
+ Path to the GLVND 'GLX' library.
+``OPENGL_opengl_LIBRARY``
+ Path to the GLVND 'OpenGL' library
+``OPENGL_gl_LIBRARY``
+ Path to the OpenGL library.  New code should prefer the ``OpenGL::*`` import
+ targets.
+
+Linux-specific
+^^^^^^^^^^^^^^
+
+Some Linux systems utilize GLVND as a new ABI for OpenGL.  GLVND separates
+context libraries from OpenGL itself; OpenGL lives in "libOpenGL", and
+contexts are defined in "libGLX" or "libEGL".  GLVND is currently the only way
+to get OpenGL 3+ functionality via EGL in a manner portable across vendors.
+Projects may use GLVND explicitly with target ``OpenGL::OpenGL`` and either
+``OpenGL::GLX`` or ``OpenGL::EGL``.
+
+Projects may use the ``OpenGL::GL`` target (or ``OPENGL_LIBRARIES`` variable)
+to use legacy GL interfaces.  These will use the legacy GL library located
+by ``OPENGL_gl_LIBRARY``, if available.  If ``OPENGL_gl_LIBRARY`` is empty or
+not found and GLVND is available, the ``OpenGL::GL`` target will use GLVND
+``OpenGL::OpenGL`` and ``OpenGL::GLX`` (and the ``OPENGL_LIBRARIES``
+variable will use the corresponding libraries).  Thus, for non-EGL-based
+Linux targets, the ``OpenGL::GL`` target is most portable.
+
+A ``OpenGL_GL_PREFERENCE`` variable may be set to specify the preferred way
+to provide legacy GL interfaces in case multiple choices are available.
+The value may be one of:
+
+``GLVND``
+ If the GLVND OpenGL and GLX libraries are available, prefer them.
+ This forces ``OPENGL_gl_LIBRARY`` to be empty.
+ This is the default if components were requested (since components
+ correspond to GLVND libraries) or if policy :policy:`CMP0072` is
+ set to ``NEW``.
+
+``LEGACY``
+ Prefer to use the legacy libGL library, if available.
+ This is the default if no components were requested and
+ policy :policy:`CMP0072` is not set to ``NEW``.
+
+For EGL targets the client must rely on GLVND support on the user's system.
+Linking should use the ``OpenGL::OpenGL OpenGL::EGL`` targets.  Using GLES*
+libraries is theoretically possible in place of ``OpenGL::OpenGL``, but this
+module does not currently support that; contributions welcome.
+
+``OPENGL_egl_LIBRARY`` and ``OPENGL_EGL_INCLUDE_DIRS`` are defined in the case of
+GLVND.  For non-GLVND Linux and other systems these are left undefined.
+
+macOS-Specific
+^^^^^^^^^^^^^^
+
+On OSX FindOpenGL defaults to using the framework version of OpenGL. People
+will have to change the cache values of OPENGL_glu_LIBRARY and
+OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX.

+----------
+
+Finds Open Multi-Processing (OpenMP) support.
+
+This module can be used to detect OpenMP support in a compiler.  If
+the compiler supports OpenMP, the flags required to compile with
+OpenMP support are returned in variables for the different languages.
+The variables may be empty if the compiler does not need a special
+flag to support OpenMP.
+
+Variables
+^^^^^^^^^
+
+The module exposes the components ``C``, ``CXX``, and ``Fortran``.
+Each of these controls the various languages to search OpenMP support for.
+
+Depending on the enabled components the following variables will be set:
+
+``OpenMP_FOUND``
+  Variable indicating that OpenMP flags for all requested languages have been found.
+  If no components are specified, this is true if OpenMP settings for all enabled languages
+  were detected.
+``OpenMP_VERSION``
+  Minimal version of the OpenMP standard detected among the requested languages,
+  or all enabled languages if no components were specified.
+
+This module will set the following variables per language in your
+project, where ``<lang>`` is one of C, CXX, or Fortran:
+
+``OpenMP_<lang>_FOUND``
+  Variable indicating if OpenMP support for ``<lang>`` was detected.
+``OpenMP_<lang>_FLAGS``
+  OpenMP compiler flags for ``<lang>``, separated by spaces.
+
+For linking with OpenMP code written in ``<lang>``, the following
+variables are provided:
+
+``OpenMP_<lang>_LIB_NAMES``
+  :ref:`;-list <CMake Language Lists>` of libraries for OpenMP programs for ``<lang>``.
+``OpenMP_<libname>_LIBRARY``
+  Location of the individual libraries needed for OpenMP support in ``<lang>``.
+``OpenMP_<lang>_LIBRARIES``
+  A list of libraries needed to link with OpenMP code written in ``<lang>``.
+
+Additionally, the module provides :prop_tgt:`IMPORTED` targets:
+
+``OpenMP::OpenMP_<lang>``
+  Target for using OpenMP from ``<lang>``.
+
+Specifically for Fortran, the module sets the following variables:
+
+``OpenMP_Fortran_HAVE_OMPLIB_HEADER``
+  Boolean indicating if OpenMP is accessible through ``omp_lib.h``.
+``OpenMP_Fortran_HAVE_OMPLIB_MODULE``
+  Boolean indicating if OpenMP is accessible through the ``omp_lib`` Fortran module.
+
+The module will also try to provide the OpenMP version variables:
+
+``OpenMP_<lang>_SPEC_DATE``
+  Date of the OpenMP specification implemented by the ``<lang>`` compiler.
+``OpenMP_<lang>_VERSION_MAJOR``
+  Major version of OpenMP implemented by the ``<lang>`` compiler.
+``OpenMP_<lang>_VERSION_MINOR``
+  Minor version of OpenMP implemented by the ``<lang>`` compiler.
+``OpenMP_<lang>_VERSION``
+  OpenMP version implemented by the ``<lang>`` compiler.
+
+The specification date is formatted as given in the OpenMP standard:
+``yyyymm`` where ``yyyy`` and ``mm`` represents the year and month of
+the OpenMP specification implemented by the ``<lang>`` compiler.

+::
+
+    OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

 .. command:: pkg_check_modules
 
- Checks for all the given modules. ::
-
-    pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
-                      [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
-                      [IMPORTED_TARGET]
-                      <MODULE> [<MODULE>]*)
+  Checks for all the given modules, setting a variety of result variables in
+  the calling scope.
 
+  .. code-block:: cmake
 
- When the ``REQUIRED`` argument was set, macros will fail with an error
- when module(s) could not be found.
-
- When the ``QUIET`` argument is set, no status messages will be printed.
-
- By default, if :variable:`CMAKE_MINIMUM_REQUIRED_VERSION` is 3.1 or
- later, or if :variable:`PKG_CONFIG_USE_CMAKE_PREFIX_PATH` is set, the
- :variable:`CMAKE_PREFIX_PATH`, :variable:`CMAKE_FRAMEWORK_PATH`, and
- :variable:`CMAKE_APPBUNDLE_PATH` cache and environment variables will
- be added to ``pkg-config`` search path.
- The ``NO_CMAKE_PATH`` and ``NO_CMAKE_ENVIRONMENT_PATH`` arguments
- disable this behavior for the cache variables and the environment
- variables, respectively.
- The ``IMPORTED_TARGET`` argument will create an imported target named
- PkgConfig::<PREFIX>> that can be passed directly as an argument to
- :command:`target_link_libraries`.
-
- It sets the following variables: ::
-
-    PKG_CONFIG_FOUND          ... if pkg-config executable was found
-    PKG_CONFIG_EXECUTABLE     ... pathname of the pkg-config program
-    PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
-                                  (since CMake 2.8.8)
-
- For the following variables two sets of values exist; first one is the
- common one and has the given PREFIX.  The second set contains flags
- which are given out when ``pkg-config`` was called with the ``--static``
- option. ::
-
-    <XPREFIX>_FOUND          ... set to 1 if module(s) exist
-    <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
-    <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
-    <XPREFIX>_LDFLAGS        ... all required linker flags
-    <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
-    <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
-    <XPREFIX>_CFLAGS         ... all required cflags
-    <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags
-
- ::
-
-    <XPREFIX> = <PREFIX>        for common case
-    <XPREFIX> = <PREFIX>_STATIC for static linking
-
- Every variable containing multiple values will be a
- :ref:`;-list <CMake Language Lists>`.
-
- There are some special variables whose prefix depends on the count of
- given modules.  When there is only one module, <PREFIX> stays
- unchanged.  When there are multiple modules, the prefix will be
- changed to <PREFIX>_<MODNAME>: ::
-
-    <XPREFIX>_VERSION    ... version of the module
-    <XPREFIX>_PREFIX     ... prefix-directory of the module
-    <XPREFIX>_INCLUDEDIR ... include-dir of the module
-    <XPREFIX>_LIBDIR     ... lib-dir of the module
-
- ::
-
-    <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
-    <XPREFIX> = <PREFIX>_<MODNAME>
-
- A <MODULE> parameter can have the following formats: ::
-
-    {MODNAME}            ... matches any version
-    {MODNAME}>={VERSION} ... at least version <VERSION> is required
-    {MODNAME}={VERSION}  ... exactly version <VERSION> is required
-    {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>
+    pkg_check_modules(<prefix>
+                      [REQUIRED] [QUIET]
+                      [NO_CMAKE_PATH]
+                      [NO_CMAKE_ENVIRONMENT_PATH]
+                      [IMPORTED_TARGET [GLOBAL]]
+                      <moduleSpec> [<moduleSpec>...])
+
+  When the ``REQUIRED`` argument is given, the command will fail with an error
+  if module(s) could not be found.
+
+  When the ``QUIET`` argument is given, no status messages will be printed.
+
+  By default, if :variable:`CMAKE_MINIMUM_REQUIRED_VERSION` is 3.1 or
+  later, or if :variable:`PKG_CONFIG_USE_CMAKE_PREFIX_PATH` is set to a
+  boolean ``True`` value, then the :variable:`CMAKE_PREFIX_PATH`,
+  :variable:`CMAKE_FRAMEWORK_PATH`, and :variable:`CMAKE_APPBUNDLE_PATH` cache
+  and environment variables will be added to the ``pkg-config`` search path.
+  The ``NO_CMAKE_PATH`` and ``NO_CMAKE_ENVIRONMENT_PATH`` arguments
+  disable this behavior for the cache variables and environment variables
+  respectively.
+
+  The ``IMPORTED_TARGET`` argument will create an imported target named
+  ``PkgConfig::<prefix>`` that can be passed directly as an argument to
+  :command:`target_link_libraries`. The ``GLOBAL`` argument will make the
+  imported target available in global scope.
+
+  Each ``<moduleSpec>`` can be either a bare module name or it can be a
+  module name with a version constraint (operators ``=``, ``<``, ``>``,
+  ``<=`` and ``>=`` are supported).  The following are examples for a module
+  named ``foo`` with various constraints:
+
+  - ``foo`` matches any version.
+  - ``foo<2`` only matches versions before 2.
+  - ``foo>=3.1`` matches any version from 3.1 or later.
+  - ``foo=1.2.3`` requires that foo must be exactly version 1.2.3.
+
+  The following variables may be set upon return.  Two sets of values exist:
+  One for the common case (``<XXX> = <prefix>``) and another for the
+  information ``pkg-config`` provides when called with the ``--static``
+  option (``<XXX> = <prefix>_STATIC``).
+
+  ``<XXX>_FOUND``
+    set to 1 if module(s) exist
+  ``<XXX>_LIBRARIES``
+    only the libraries (without the '-l')
+  ``<XXX>_LINK_LIBRARIES``
+    the libraries and their absolute paths
+  ``<XXX>_LIBRARY_DIRS``
+    the paths of the libraries (without the '-L')
+  ``<XXX>_LDFLAGS``
+    all required linker flags
+  ``<XXX>_LDFLAGS_OTHER``
+    all other linker flags
+  ``<XXX>_INCLUDE_DIRS``
+    the '-I' preprocessor flags (without the '-I')
+  ``<XXX>_CFLAGS``
+    all required cflags
+  ``<XXX>_CFLAGS_OTHER``
+    the other compiler flags
+
+  All but ``<XXX>_FOUND`` may be a :ref:`;-list <CMake Language Lists>` if the
+  associated variable returned from ``pkg-config`` has multiple values.
+
+  There are some special variables whose prefix depends on the number of
+  ``<moduleSpec>`` given.  When there is only one ``<moduleSpec>``,
+  ``<YYY>`` will simply be ``<prefix>``, but if two or more ``<moduleSpec>``
+  items are given, ``<YYY>`` will be ``<prefix>_<moduleName>``.
+
+  ``<YYY>_VERSION``
+    version of the module
+  ``<YYY>_PREFIX``
+    prefix directory of the module
+  ``<YYY>_INCLUDEDIR``
+    include directory of the module
+  ``<YYY>_LIBDIR``
+    lib directory of the module
+
+  Examples:

-# -------
-#
-# Finding and Using Qt4
-# ^^^^^^^^^^^^^^^^^^^^^
-#
-# This module can be used to find Qt4.  The most important issue is that
-# the Qt4 qmake is available via the system path.  This qmake is then
-# used to detect basically everything else.  This module defines a
-# number of :prop_tgt:`IMPORTED` targets, macros and variables.
-#
-# Typical usage could be something like:
-#
-# .. code-block:: cmake
-#
-#    set(CMAKE_AUTOMOC ON)
-#    set(CMAKE_INCLUDE_CURRENT_DIR ON)
-#    find_package(Qt4 4.4.3 REQUIRED QtGui QtXml)
-#    add_executable(myexe main.cpp)
-#    target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
-#
-# .. note::
-#
-#  When using :prop_tgt:`IMPORTED` targets, the qtmain.lib static library is
-#  automatically linked on Windows for :prop_tgt:`WIN32 <WIN32_EXECUTABLE>`
-#  executables. To disable that globally, set the
-#  ``QT4_NO_LINK_QTMAIN`` variable before finding Qt4. To disable that
-#  for a particular executable, set the ``QT4_NO_LINK_QTMAIN`` target
-#  property to ``TRUE`` on the executable.
-#
-# Qt Build Tools
-# ^^^^^^^^^^^^^^
-#
-# Qt relies on some bundled tools for code generation, such as ``moc`` for
-# meta-object code generation,``uic`` for widget layout and population,
-# and ``rcc`` for virtual filesystem content generation.  These tools may be
-# automatically invoked by :manual:`cmake(1)` if the appropriate conditions
-# are met.  See :manual:`cmake-qt(7)` for more.
-#
-# Qt Macros
-# ^^^^^^^^^
-#
-# In some cases it can be necessary or useful to invoke the Qt build tools in a
-# more-manual way. Several macros are available to add targets for such uses.
-#
-# ::
-#
-#   macro QT4_WRAP_CPP(outfiles inputfile ... [TARGET tgt] OPTIONS ...)
-#         create moc code from a list of files containing Qt class with
-#         the Q_OBJECT declaration.  Per-directory preprocessor definitions
-#         are also added.  If the <tgt> is specified, the
-#         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
-#         the <tgt> are passed to moc.  Options may be given to moc, such as
-#         those found when executing "moc -help".
-#
-#
-# ::
-#
-#   macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
-#         create code from a list of Qt designer ui files.

-#         when executing "rcc -help"
-#
-#

-#
-#   macro QT4_GENERATE_MOC(inputfile outputfile [TARGET tgt])
-#         creates a rule to run moc on infile and create outfile.
-#         Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
-#         because you need a custom filename for the moc file or something
-#         similar.  If the <tgt> is specified, the
-#         INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from
-#         the <tgt> are passed to moc.

-#         Create the interface header and implementation files with the
-#         given basename from the given interface xml file and add it to
-#         the list of sources.
-#
-#         You can pass additional parameters to the qdbusxml2cpp call by setting
-#         properties on the input file:
-#
-#         INCLUDE the given file will be included in the generate interface header
-#

-#         The qm files are generated in the build tree.
-#         Updating the translations can be done by adding the qm_files
-#         to the source list of your library/executable, so they are

-#         So if you have the files foo.h and foo.cpp, and in foo.h a

-#         Make <target> use the <modules> from Qt. Using a Qt module means
-#         to link to the library, add the relevant include directories for the
-#         module, and add the relevant compiler defines for using the module.
-#         Modules are roughly equivalent to components of Qt4, so usage would be
-#         something like:
-#          qt4_use_modules(myexe Core Gui Declarative)
-#         to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
-#         can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the
-#         same argument to the target_link_libraries call.
-#
-#
-# IMPORTED Targets
-# ^^^^^^^^^^^^^^^^
-#
-# A particular Qt library may be used by using the corresponding

-# command:
-#
-# .. code-block:: cmake
-#
-#   target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
-#
-# Using a target in this way causes :cmake(1)` to use the appropriate include
-# directories and compile definitions for the target when compiling ``myexe``.
-#
-# Targets are aware of their dependencies, so for example it is not necessary
-# to list ``Qt4::QtCore`` if another Qt library is listed, and it is not
-# necessary to list ``Qt4::QtGui`` if ``Qt4::QtDeclarative`` is listed.
-# Targets may be tested for existence in the usual way with the

+        instead.
+        Make <target> use the <modules> from Qt. Using a Qt module means
+        to link to the library, add the relevant include directories for the
+        module, and add the relevant compiler defines for using the module.
+        Modules are roughly equivalent to components of Qt4, so usage would be
+        something like:
+         qt4_use_modules(myexe Core Gui Declarative)
+        to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
+        can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the
+        same argument to the target_link_libraries call.
+
+
+IMPORTED Targets
+^^^^^^^^^^^^^^^^
+
+A particular Qt library may be used by using the corresponding
+:prop_tgt:`IMPORTED` target with the :command:`target_link_libraries`
+command:
+
+.. code-block:: cmake
+
+  target_link_libraries(myexe Qt4::QtGui Qt4::QtXml)
+
+Using a target in this way causes :cmake(1)` to use the appropriate include
+directories and compile definitions for the target when compiling ``myexe``.
+
+Targets are aware of their dependencies, so for example it is not necessary
+to list ``Qt4::QtCore`` if another Qt library is listed, and it is not
+necessary to list ``Qt4::QtGui`` if ``Qt4::QtDeclarative`` is listed.
+Targets may be tested for existence in the usual way with the
+:command:`if(TARGET)` command.
+
+The Qt toolkit may contain both debug and release libraries.
+:manual:`cmake(1)` will choose the appropriate version based on the build
+configuration.

+Result Variables
+^^^^^^^^^^^^^^^^
+
+  Below is a detailed list of variables that FindQt4.cmake sets.
+
+``Qt4_FOUND``
+ If false, don't try to use Qt 4.
+``QT_FOUND``
+ If false, don't try to use Qt. This variable is for compatibility only.
+``QT4_FOUND``
+ If false, don't try to use Qt 4. This variable is for compatibility only.
+``QT_VERSION_MAJOR``
+ The major version of Qt found.
+``QT_VERSION_MINOR``
+ The minor version of Qt found.
+``QT_VERSION_PATCH``
+ The patch version of Qt found.

+
+
+This is part of the ``Findosg*`` suite used to find OpenSceneGraph
+components.  Each component is separate and you must opt in to each
+module.  You must also opt into OpenGL and OpenThreads (and Producer
+if needed) as these modules won't do it for you.  This is to allow you
+control over your own system piece by piece in case you need to opt
+out of certain components or change the Find behavior for a particular
+module (perhaps because the default :module:`FindOpenGL` module doesn't
+work with your system as an example).  If you want to use a more
+convenient module that includes everything, use the
+:module:`FindOpenSceneGraph` instead of the ``Findosg*.cmake`` modules.
+
+Locate osgDB This module defines:
+

-# GenerateExportHeader
-# --------------------
-#
-# Function for generation of export macros for libraries
-#
-# This module provides the function GENERATE_EXPORT_HEADER().
-#
-# The ``GENERATE_EXPORT_HEADER`` function can be used to generate a file
-# suitable for preprocessor inclusion which contains EXPORT macros to be
-# used in library classes::
-#
-#    GENERATE_EXPORT_HEADER( LIBRARY_TARGET
-#              [BASE_NAME <base_name>]
-#              [EXPORT_MACRO_NAME <export_macro_name>]
-#              [EXPORT_FILE_NAME <export_file_name>]
-#              [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
-#              [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
-#              [STATIC_DEFINE <static_define>]
-#              [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
-#              [DEFINE_NO_DEPRECATED]
-#              [PREFIX_NAME <prefix_name>]
-#              [CUSTOM_CONTENT_FROM_VARIABLE <variable>]
-#    )
-#
-#
-# The target properties :prop_tgt:`CXX_VISIBILITY_PRESET <<LANG>_VISIBILITY_PRESET>`
-# and :prop_tgt:`VISIBILITY_INLINES_HIDDEN` can be used to add the appropriate
-# compile flags for targets.  See the documentation of those target properties,
-# and the convenience variables
-# :variable:`CMAKE_CXX_VISIBILITY_PRESET <CMAKE_<LANG>_VISIBILITY_PRESET>` and
-# :variable:`CMAKE_VISIBILITY_INLINES_HIDDEN`.
-#
-# By default ``GENERATE_EXPORT_HEADER()`` generates macro names in a file
-# name determined by the name of the library.  This means that in the
-# simplest case, users of ``GenerateExportHeader`` will be equivalent to:
-#
-# .. code-block:: cmake
-#
-#    set(CMAKE_CXX_VISIBILITY_PRESET hidden)
-#    set(CMAKE_VISIBILITY_INLINES_HIDDEN 1)
-#    add_library(somelib someclass.cpp)
-#    generate_export_header(somelib)
-#    install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
-#    install(FILES
-#     someclass.h
-#     ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
-#    )
-#
-#
-# And in the ABI header files:
-#
-# .. code-block:: c++
-#
-#    #include "somelib_export.h"
-#    class SOMELIB_EXPORT SomeClass {
-#      ...
-#    };
-#
-#
-# The CMake fragment will generate a file in the
-# ``${CMAKE_CURRENT_BINARY_DIR}`` called ``somelib_export.h`` containing the
-# macros ``SOMELIB_EXPORT``, ``SOMELIB_NO_EXPORT``, ``SOMELIB_DEPRECATED``,
-# ``SOMELIB_DEPRECATED_EXPORT`` and ``SOMELIB_DEPRECATED_NO_EXPORT``.
-# They will be followed by content taken from the variable specified by
-# the ``CUSTOM_CONTENT_FROM_VARIABLE`` option, if any.
-# The resulting file should be installed with other headers in the library.
-#
-# The ``BASE_NAME`` argument can be used to override the file name and the
-# names used for the macros:
-#
-# .. code-block:: cmake
-#
-#    add_library(somelib someclass.cpp)
-#    generate_export_header(somelib
-#      BASE_NAME other_name
-#    )
-#
-#
-# Generates a file called ``other_name_export.h`` containing the macros
-# ``OTHER_NAME_EXPORT``, ``OTHER_NAME_NO_EXPORT`` and ``OTHER_NAME_DEPRECATED``
-# etc.
-#
-# The ``BASE_NAME`` may be overridden by specifying other options in the
-# function.  For example:
-#
-# .. code-block:: cmake
-#
-#    add_library(somelib someclass.cpp)
-#    generate_export_header(somelib
-#      EXPORT_MACRO_NAME OTHER_NAME_EXPORT
-#    )
-#
-#
-# creates the macro ``OTHER_NAME_EXPORT`` instead of ``SOMELIB_EXPORT``, but
-# other macros and the generated file name is as default:
-#
-# .. code-block:: cmake
-#
-#    add_library(somelib someclass.cpp)
-#    generate_export_header(somelib
-#      DEPRECATED_MACRO_NAME KDE_DEPRECATED
-#    )
-#
-#
-# creates the macro ``KDE_DEPRECATED`` instead of ``SOMELIB_DEPRECATED``.
-#
-# If ``LIBRARY_TARGET`` is a static library, macros are defined without
-# values.
-#
-# If the same sources are used to create both a shared and a static
-# library, the uppercased symbol ``${BASE_NAME}_STATIC_DEFINE`` should be
-# used when building the static library:
-#
-# .. code-block:: cmake
-#
-#    add_library(shared_variant SHARED ${lib_SRCS})
-#    add_library(static_variant ${lib_SRCS})
-#    generate_export_header(shared_variant BASE_NAME libshared_and_static)
-#    set_target_properties(static_variant PROPERTIES
-#      COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)
-#
-# This will cause the export macros to expand to nothing when building
-# the static library.
-#
-# If ``DEFINE_NO_DEPRECATED`` is specified, then a macro
-# ``${BASE_NAME}_NO_DEPRECATED`` will be defined This macro can be used to
-# remove deprecated code from preprocessor output:
-#
-# .. code-block:: cmake
-#
-#    option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
-#    if (EXCLUDE_DEPRECATED)
-#      set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
-#    endif()
-#    generate_export_header(somelib ${NO_BUILD_DEPRECATED})
-#
-#
-# And then in somelib:
-#
-# .. code-block:: c++
-#
-#    class SOMELIB_EXPORT SomeClass
-#    {
-#    public:

-#
-# .. code-block:: c++
-#
-#    #ifndef SOMELIB_NO_DEPRECATED
-#    void SomeClass::oldMethod() {  }
-#    #endif
-#
-#
-# If ``PREFIX_NAME`` is specified, the argument will be used as a prefix to

-#
-# For example:
-#
-# .. code-block:: cmake
-#
-#    generate_export_header(somelib PREFIX_NAME VTK_)
-#
-# Generates the macros ``VTK_SOMELIB_EXPORT`` etc.
-#

+GenerateExportHeader
+--------------------
 
+Function for generation of export macros for libraries
+
+This module provides the function ``GENERATE_EXPORT_HEADER()``.
+
+The ``GENERATE_EXPORT_HEADER`` function can be used to generate a file
+suitable for preprocessor inclusion which contains EXPORT macros to be
+used in library classes::
+
+   GENERATE_EXPORT_HEADER( LIBRARY_TARGET
+             [BASE_NAME <base_name>]
+             [EXPORT_MACRO_NAME <export_macro_name>]
+             [EXPORT_FILE_NAME <export_file_name>]
+             [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
+             [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
+             [INCLUDE_GUARD_NAME <include_guard_name>]
+             [STATIC_DEFINE <static_define>]
+             [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
+             [DEFINE_NO_DEPRECATED]
+             [PREFIX_NAME <prefix_name>]
+             [CUSTOM_CONTENT_FROM_VARIABLE <variable>]
+   )
+
+
+The target properties :prop_tgt:`CXX_VISIBILITY_PRESET <<LANG>_VISIBILITY_PRESET>`
+and :prop_tgt:`VISIBILITY_INLINES_HIDDEN` can be used to add the appropriate
+compile flags for targets.  See the documentation of those target properties,
+and the convenience variables
+:variable:`CMAKE_CXX_VISIBILITY_PRESET <CMAKE_<LANG>_VISIBILITY_PRESET>` and
+:variable:`CMAKE_VISIBILITY_INLINES_HIDDEN`.
+
+By default ``GENERATE_EXPORT_HEADER()`` generates macro names in a file
+name determined by the name of the library.  This means that in the
+simplest case, users of ``GenerateExportHeader`` will be equivalent to:
+
+.. code-block:: cmake
+
+   set(CMAKE_CXX_VISIBILITY_PRESET hidden)
+   set(CMAKE_VISIBILITY_INLINES_HIDDEN 1)
+   add_library(somelib someclass.cpp)
+   generate_export_header(somelib)
+   install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
+   install(FILES
+    someclass.h
+    ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
+   )
+
+
+And in the ABI header files:
+
+.. code-block:: c++
+
+   #include "somelib_export.h"
+   class SOMELIB_EXPORT SomeClass {
+     ...
+   };
+
+
+The CMake fragment will generate a file in the
+``${CMAKE_CURRENT_BINARY_DIR}`` called ``somelib_export.h`` containing the
+macros ``SOMELIB_EXPORT``, ``SOMELIB_NO_EXPORT``, ``SOMELIB_DEPRECATED``,
+``SOMELIB_DEPRECATED_EXPORT`` and ``SOMELIB_DEPRECATED_NO_EXPORT``.
+They will be followed by content taken from the variable specified by
+the ``CUSTOM_CONTENT_FROM_VARIABLE`` option, if any.
+The resulting file should be installed with other headers in the library.
+
+The ``BASE_NAME`` argument can be used to override the file name and the
+names used for the macros:
+
+.. code-block:: cmake
+
+   add_library(somelib someclass.cpp)
+   generate_export_header(somelib
+     BASE_NAME other_name
+   )
+
+
+Generates a file called ``other_name_export.h`` containing the macros
+``OTHER_NAME_EXPORT``, ``OTHER_NAME_NO_EXPORT`` and ``OTHER_NAME_DEPRECATED``
+etc.
+
+The ``BASE_NAME`` may be overridden by specifying other options in the
+function.  For example:
+
+.. code-block:: cmake
+
+   add_library(somelib someclass.cpp)
+   generate_export_header(somelib
+     EXPORT_MACRO_NAME OTHER_NAME_EXPORT
+   )
+
+
+creates the macro ``OTHER_NAME_EXPORT`` instead of ``SOMELIB_EXPORT``, but
+other macros and the generated file name is as default:
+
+.. code-block:: cmake
+
+   add_library(somelib someclass.cpp)
+   generate_export_header(somelib
+     DEPRECATED_MACRO_NAME KDE_DEPRECATED
+   )
+
+
+creates the macro ``KDE_DEPRECATED`` instead of ``SOMELIB_DEPRECATED``.
+
+If ``LIBRARY_TARGET`` is a static library, macros are defined without
+values.
+
+If the same sources are used to create both a shared and a static
+library, the uppercased symbol ``${BASE_NAME}_STATIC_DEFINE`` should be
+used when building the static library:
+
+.. code-block:: cmake
+
+   add_library(shared_variant SHARED ${lib_SRCS})
+   add_library(static_variant ${lib_SRCS})
+   generate_export_header(shared_variant BASE_NAME libshared_and_static)
+   set_target_properties(static_variant PROPERTIES
+     COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)
+
+This will cause the export macros to expand to nothing when building
+the static library.
+
+If ``DEFINE_NO_DEPRECATED`` is specified, then a macro
+``${BASE_NAME}_NO_DEPRECATED`` will be defined This macro can be used to
+remove deprecated code from preprocessor output:
+
+.. code-block:: cmake
+
+   option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
+   if (EXCLUDE_DEPRECATED)
+     set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
+   endif()
+   generate_export_header(somelib ${NO_BUILD_DEPRECATED})
+
+
+And then in somelib:
+
+.. code-block:: c++
+
+   class SOMELIB_EXPORT SomeClass
+   {
+   public:
+   #ifndef SOMELIB_NO_DEPRECATED
+     SOMELIB_DEPRECATED void oldMethod();
+   #endif
+   };
+
+.. code-block:: c++
+
+   #ifndef SOMELIB_NO_DEPRECATED
+   void SomeClass::oldMethod() {  }
+   #endif
+
+
+If ``PREFIX_NAME`` is specified, the argument will be used as a prefix to
+all generated macros.
+
+For example:
+
+.. code-block:: cmake
+
+   generate_export_header(somelib PREFIX_NAME VTK_)
+
+Generates the macros ``VTK_SOMELIB_EXPORT`` etc.
+
+::
+
+   ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )
+
+The ``ADD_COMPILER_EXPORT_FLAGS`` function adds ``-fvisibility=hidden`` to
+:variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` if supported, and is a no-op
+on Windows which does not need extra compiler flags for exporting support.
+You may optionally pass a single argument to ``ADD_COMPILER_EXPORT_FLAGS``
+that will be populated with the ``CXX_FLAGS`` required to enable visibility
+support for the compiler/architecture in use.
+
+This function is deprecated.  Set the target properties

+This module provides functions to list the .dll, .dylib or .so files
+that an executable or shared library file depends on.  (Its
+prerequisites.)
+
+It uses various tools to obtain the list of required shared library
+files:
+
+::
+
+   dumpbin (Windows)
+   objdump (MinGW on Windows)
+   ldd (Linux/Unix)
+   otool (Mac OSX)
+
+The following functions are provided by this module:

+  GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
+                    <exepath> <dirs> [<rpaths>])
+
+Get the list of shared library files required by <target>.  The list
+in the variable named <prerequisites_var> should be empty on first
+entry to this function.  On exit, <prerequisites_var> will contain the
+list of required shared library files.
+
+<target> is the full path to an executable file.  <prerequisites_var>
+is the name of a CMake variable to contain the results.
+<exclude_system> must be 0 or 1 indicating whether to include or
+exclude "system" prerequisites.  If <recurse> is set to 1 all
+prerequisites will be found recursively, if set to 0 only direct
+prerequisites are listed.  <exepath> is the path to the top level
+executable used for @executable_path replacment on the Mac.  <dirs> is
+a list of paths where libraries might be found: these paths are
+searched first when a target without any path info is given.  Then
+standard system locations are also searched: PATH, Framework
+locations, /usr/lib...
+
+The variable GET_PREREQUISITES_VERBOSE can be set to true to enable verbose
+output.

+Print the prerequisites of shared library and executable files
+matching a globbing pattern.  <glob_arg> is GLOB or GLOB_RECURSE and
+<glob_exp> is a globbing expression used with "file(GLOB" or
+"file(GLOB_RECURSE" to retrieve a list of matching files.  If a
+matching file is executable, its prerequisites are listed.

+This module defines functions to help use the Google Test infrastructure.  Two
+mechanisms for adding tests are provided. :command:`gtest_add_tests` has been
+around for some time, originally via ``find_package(GTest)``.
+:command:`gtest_discover_tests` was introduced in CMake 3.10.
+
+The (older) :command:`gtest_add_tests` scans source files to identify tests.
+This is usually effective, with some caveats, including in cross-compiling
+environments, and makes setting additional properties on tests more convenient.
+However, its handling of parameterized tests is less comprehensive, and it
+requires re-running CMake to detect changes to the list of tests.
+
+The (newer) :command:`gtest_discover_tests` discovers tests by asking the
+compiled test executable to enumerate its tests.  This is more robust and
+provides better handling of parameterized tests, and does not require CMake
+to be re-run when tests change.  However, it may not work in a cross-compiling
+environment, and setting test properties is less convenient.
+
+More details can be found in the documentation of the respective functions.
+
+Both commands are intended to replace use of :command:`add_test` to register
+tests, and will create a separate CTest test for each Google Test test case.
+Note that this is in some cases less efficient, as common set-up and tear-down
+logic cannot be shared by multiple test cases executing in the same instance.
+However, it provides more fine-grained pass/fail information to CTest, which is
+usually considered as more beneficial.  By default, the CTest test name is the
+same as the Google Test name (i.e. ``suite.testcase``); see also
+``TEST_PREFIX`` and ``TEST_SUFFIX``.

+    Specifies additional properties to be set on all tests discovered by this
+    invocation of ``gtest_discover_tests``.
+
+  ``TEST_LIST var``
+    Make the list of tests available in the variable ``var``, rather than the
+    default ``<target>_TESTS``.  This can be useful when the same test
+    executable is being used in multiple calls to ``gtest_discover_tests()``.
+    Note that this variable is only available in CTest.
+
+  ``DISCOVERY_TIMEOUT num``
+    Specifies how long (in seconds) CMake will wait for the test to enumerate
+    available tests.  If the test takes longer than this, discovery (and your
+    build) will fail.  Most test executables will enumerate their tests very
+    quickly, but under some exceptional circumstances, a test may require a
+    longer timeout.  The default is 5.  See also the ``TIMEOUT`` option of
+    :command:`execute_process`.
+
+    .. note::
+
+      In CMake versions 3.10.1 and 3.10.2, this option was called ``TIMEOUT``.
+      This clashed with the ``TIMEOUT`` test property, which is one of the
+      common properties that would be set with the ``PROPERTIES`` keyword,
+      usually leading to legal but unintended behavior.  The keyword was
+      changed to ``DISCOVERY_TIMEOUT`` in CMake 3.10.3 to address this
+      problem.  The ambiguous behavior of the ``TIMEOUT`` keyword in 3.10.1
+      and 3.10.2 has not been preserved.

-# This command creates a <target_name>.jar.  It compiles the given
-# source files (source) and adds the given resource files (resource) to
-# the jar file.  Source files can be java files or listing files
-# (prefixed by '@').  If only resource files are given then just a jar file
-# is created.  The list of include jars are added to the classpath when
-# compiling the java sources and also to the dependencies of the target.
-# INCLUDE_JARS also accepts other target names created by add_jar.  For
-# backwards compatibility, jar files listed as sources are ignored (as
-# they have been since the first version of this module).
-#
-# The default OUTPUT_DIR can also be changed by setting the variable
-# CMAKE_JAVA_TARGET_OUTPUT_DIR.
-#
-# Additional instructions:
-#
-# ::
-#
-#    To add compile flags to the target you can set these flags with
-#    the following variable:
-#
-#
-#
-# ::
-#
-#        set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
-#
-#
-#
-# ::
-#
-#    To add a path or a jar file to the class path you can do this
-#    with the CMAKE_JAVA_INCLUDE_PATH variable.
-#
-#
-#
-# ::
-#
-#        set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
-#
-#
-#
-# ::
-#
-#    To use a different output name for the target you can set it with:
-#
-#
-#
-# ::
-#
-#        add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)
-#
-#
-#
-# ::
-#
-#    To use a different output directory than CMAKE_CURRENT_BINARY_DIR
-#    you can set it with:
-#
-#
-#
-# ::
-#
-#        add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
-#
-#
-#
-# ::
-#
-#    To define an entry point in your jar you can set it with the ENTRY_POINT
-#    named argument:
-#
-#
-#
-# ::
-#
-#        add_jar(example ENTRY_POINT com/examples/MyProject/Main)
-#
-#
-#
-# ::
-#
-#    To define a custom manifest for the jar, you can set it with the manifest
-#    named argument:
-#
-#
-#
-# ::
-#
-#        add_jar(example MANIFEST /path/to/manifest)
-#
-#
-#
-# ::
-#
-#    To add a VERSION to the target output name you can set it using
-#    the VERSION named argument to add_jar. This will create a jar file with the
-#    name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
-#    pointing to the jar with the version information.
-#
-#
-#
-# ::
-#
-#        add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
-#
-#
-#
-# ::
-#
-#     If the target is a JNI library, utilize the following commands to
-#     create a JNI symbolic link:
-#
-#
-#
-# ::
-#
-#        set(CMAKE_JNI_TARGET TRUE)
-#        add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
-#        install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
-#        install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
-#
-#
-#
-# ::
-#
-#     If a single target needs to produce more than one jar from its
-#     java source code, to prevent the accumulation of duplicate class
-#     files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
-#     to calling the add_jar() function:
-#
-#
-#
-# ::
-#
-#        set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
-#        add_jar(foo foo.java)

-# Target Properties:
-#
-# ::
-#
-#    The add_jar() function sets some target properties. You can get these
-#    properties with the
-#       get_property(TARGET <target_name> PROPERTY <propery_name>)

-#                       This is used by install_jni_symlink().
-#    JAR_FILE           The location of the jar file so that you can include

+
+Creating And Installing JARs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: cmake
+
+  add_jar(<target_name>
+          [SOURCES] <source1> [<source2>...] [<resource1>...]
+          [INCLUDE_JARS <jar1> [<jar2>...]]
+          [ENTRY_POINT <entry>]
+          [VERSION <version>]
+          [OUTPUT_NAME <name>]
+          [OUTPUT_DIR <dir>]
+          [GENERATE_NATIVE_HEADERS <target> [DESTINATION <dir>]]
+          )
+
+This command creates a ``<target_name>.jar``.  It compiles the given
+``<source>`` files and adds the given ``<resource>`` files to
+the jar file.  Source files can be java files or listing files
+(prefixed by ``@``).  If only resource files are given then just a jar file
+is created.  The list of ``INCLUDE_JARS`` are added to the classpath when
+compiling the java sources and also to the dependencies of the target.
+``INCLUDE_JARS`` also accepts other target names created by ``add_jar()``.
+For backwards compatibility, jar files listed as sources are ignored (as
+they have been since the first version of this module).
+
+The default ``OUTPUT_DIR`` can also be changed by setting the variable
+``CMAKE_JAVA_TARGET_OUTPUT_DIR``.
+
+Optionally, using option ``GENERATE_NATIVE_HEADERS``, native header files can
+be generated for methods declared as native.  These files provide the
+connective glue that allow your Java and C code to interact.  An INTERFACE
+target will be created for an easy usage of generated files.  Sub-option
+``DESTINATION`` can be used to specify the output directory for generated
+header files.
+
+``GENERATE_NATIVE_HEADERS`` option requires, at least, version 1.8 of the JDK.
+
+The ``add_jar()`` function sets the following target properties on
+``<target_name>``:
+
+``INSTALL_FILES``
+  The files which should be installed.  This is used by ``install_jar()``.
+``JNI_SYMLINK``
+  The JNI symlink which should be installed.  This is used by
+  ``install_jni_symlink()``.
+``JAR_FILE``
+  The location of the jar file so that you can include it.
+``CLASSDIR``
+  The directory where the class files can be found.  For example to use them
+  with ``javah``.
+
+.. code-block:: cmake
+
+ install_jar(<target_name> <destination>)
+ install_jar(<target_name> DESTINATION <destination> [COMPONENT <component>])
+
+This command installs the ``<target_name>`` files to the given
+``<destination>``.  It should be called in the same scope as ``add_jar()`` or
+it will fail.
+
+The ``install_jar()`` function sets the ``INSTALL_DESTINATION`` target
+property on jars so installed.  This property holds the ``<destination>`` as
+described above, and is used by ``install_jar_exports()``.  You can get this
+information with :command:`get_property` and the ``INSTALL_DESTINATION``
+property key.
+
+.. code-block:: cmake
+
+ install_jni_symlink(<target_name> <destination>)
+ install_jni_symlink(<target_name> DESTINATION <destination> [COMPONENT <component>])
+
+This command installs the ``<target_name>`` JNI symlinks to the given
+``<destination>``.  It should be called in the same scope as ``add_jar()`` or
+it will fail.
+
+.. code-block:: cmake
+
+ install_jar_exports(TARGETS <jars>...
+                     [NAMESPACE <namespace>]
+                     FILE <filename>
+                     DESTINATION <destination> [COMPONENT <component>])
+
+This command installs a target export file ``<filename>`` for the named jar
+targets to the given ``<destination>`` directory.  Its function is similar to
+that of :command:`install(EXPORTS)`.
+
+.. code-block:: cmake
+
+ export_jars(TARGETS <jars>...
+             [NAMESPACE <namespace>]
+             FILE <filename>)
+
+This command writes a target export file ``<filename>`` for the named ``<jars>``
+targets.  Its function is similar to that of :command:`export`.
+
+
+Examples
+""""""""
+
+To add compile flags to the target you can set these flags with the following
+variable:
+
+.. code-block:: cmake
+
+  set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
+
+
+To add a path or a jar file to the class path you can do this with the
+``CMAKE_JAVA_INCLUDE_PATH`` variable.
+
+.. code-block:: cmake
+
+  set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
+
+To use a different output name for the target you can set it with:
+
+.. code-block:: cmake
+
+  add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)
+
+To use a different output directory than ``CMAKE_CURRENT_BINARY_DIR`` you can
+set it with:
+
+.. code-block:: cmake
+
+  add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
+
+To define an entry point in your jar you can set it with the ``ENTRY_POINT``
+named argument:
+
+.. code-block:: cmake
+
+  add_jar(example ENTRY_POINT com/examples/MyProject/Main)
+
+To define a custom manifest for the jar, you can set it with the ``MANIFEST``
+named argument:
+
+.. code-block:: cmake
+
+  add_jar(example MANIFEST /path/to/manifest)
+
+To add a version to the target output name you can set it using the ``VERSION``
+named argument to ``add_jar()``.  The following example will create a jar file
+with the name ``shibboleet-1.0.0.jar`` and will create a symlink
+``shibboleet.jar`` pointing to the jar with the version information.
+
+.. code-block:: cmake
+
+  add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
+
+If the target is a JNI library, utilize the following commands to
+create a JNI symbolic link:
+
+.. code-block:: cmake
+
+  set(CMAKE_JNI_TARGET TRUE)
+  add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
+  install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
+  install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
+
+If a single target needs to produce more than one jar from its
+java source code, to prevent the accumulation of duplicate class
+files in subsequent jars, set/reset ``CMAKE_JAR_CLASSES_PREFIX`` prior
+to calling the ``add_jar()`` function:
+
+.. code-block:: cmake
+
+  set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
+  add_jar(foo foo.java)
+
+  set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
+  add_jar(bar bar.java)
+
+For an optimum usage of option ``GENERATE_NATIVE_HEADERS``, it is recommended to
+include module JNI before any call to ``add_jar()``. The produced target for
+native headers can then be used to compile C/C++ sources with the
+:command:`target_link_libraries` command.
+
+.. code-block:: cmake
+
+  find_package(JNI)
+  add_jar(foo foo.java GENERATE_NATIVE_HEADERS foo-native)
+  add_library(bar bar.cpp)
+  target_link_libraries(bar PRIVATE foo-native)
+
+
+Finding JARs
+^^^^^^^^^^^^
+
+.. code-block:: cmake
+
+  find_jar(<VAR>
+           <name> | NAMES <name1> [<name2>...]
+           [PATHS <path1> [<path2>... ENV <var>]]
+           [VERSIONS <version1> [<version2>]]
+           [DOC "cache documentation string"]
+          )
+
+This command is used to find a full path to the named jar.  A cache
+entry named by ``<VAR>`` is created to store the result of this command.
+If the full path to a jar is found the result is stored in the
+variable and the search will not repeated unless the variable is
+cleared.  If nothing is found, the result will be ``<VAR>-NOTFOUND``, and
+the search will be attempted again next time ``find_jar()`` is invoked with
+the same variable.  The name of the full path to a file that is
+searched for is specified by the names listed after ``NAMES`` argument.
+Additional search locations can be specified after the ``PATHS`` argument.
+If you require special a version of a jar file you can specify it with
+the ``VERSIONS`` argument.  The argument after ``DOC`` will be used for the
+documentation string in the cache.
+
+
+Javadoc
+^^^^^^^
+
+The ``create_javadoc()`` command can be used to create java documentation
+based on files or packages.  For more details please read the javadoc manpage.
+
+There are two main signatures for ``create_javadoc()``.  The first signature
+works with package names on a path with source files.
+
+.. code-block:: cmake
+
+ create_javadoc(<VAR>
+                PACKAGES <pkg1> [<pkg2>...]
+                [SOURCEPATH <sourcepath>]
+                [CLASSPATH <classpath>]
+                [INSTALLPATH <install path>]
+                [DOCTITLE "the documentation title"]
+                [WINDOWTITLE "the title of the document"]
+                [AUTHOR TRUE|FALSE]
+                [USE TRUE|FALSE]
+                [VERSION TRUE|FALSE]
+                )
+
+For example:
+
+.. code-block:: cmake
+
+  create_javadoc(my_example_doc
+    PACKAGES com.example.foo com.example.bar
+    SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
+    CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
+    WINDOWTITLE "My example"
+    DOCTITLE "<h1>My example</h1>"
+    AUTHOR TRUE
+    USE TRUE
+    VERSION TRUE
+  )
+
+The second signature for ``create_javadoc()`` works on a given list of
+files.
+
+.. code-block:: cmake
+
+  create_javadoc(<VAR>
+                 FILES <file1> [<file2>...]
+                 [CLASSPATH <classpath>]
+                 [INSTALLPATH <install path>]
+                 [DOCTITLE "the documentation title"]
+                 [WINDOWTITLE "the title of the document"]
+                 [AUTHOR TRUE|FALSE]
+                 [USE TRUE|FALSE]
+                 [VERSION TRUE|FALSE]
+                )
+
+For example:
+
+.. code-block:: cmake
+
+  create_javadoc(my_example_doc
+    FILES ${example_SRCS}
+    CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
+    WINDOWTITLE "My example"
+    DOCTITLE "<h1>My example</h1>"
+    AUTHOR TRUE
+    USE TRUE
+    VERSION TRUE
+  )
+
+Both signatures share most of the options.  These options are the same
+as what you can find in the javadoc manpage.  Please look at the
+manpage for ``CLASSPATH``, ``DOCTITLE``, ``WINDOWTITLE``, ``AUTHOR``, ``USE``
+and ``VERSION``.
+
+If you don't set the ``INSTALLPATH``, then by default the documentation will
+be installed to :
+
+::
+
+   ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
+
+
+Header Generation
+^^^^^^^^^^^^^^^^^
+
+.. code-block:: cmake
+
+ create_javah(TARGET <target> | GENERATED_FILES <VAR>
+              CLASSES <class>...
+              [CLASSPATH <classpath>...]
+              [DEPENDS <depend>...]
+              [OUTPUT_NAME <path>|OUTPUT_DIR <path>]
+              )
+
+Create C header files from java classes. These files provide the connective glue
+that allow your Java and C code to interact.
+
+.. deprecated:: 3.11
+
+.. note::
+
+  This command will no longer be supported starting with version 10 of the JDK
+  due to the `suppression of javah tool <http://openjdk.java.net/jeps/313>`_.
+  The ``add_jar(GENERATE_NATIVE_HEADERS)`` command should be used instead.
+
+There are two main signatures for ``create_javah()``.  The first signature
+returns generated files through variable specified by the ``GENERATED_FILES``
+option.  For example:
+
+.. code-block:: cmake
+
+  create_javah(GENERATED_FILES files_headers
+    CLASSES org.cmake.HelloWorld
+    CLASSPATH hello.jar
+  )
+
+The second signature for ``create_javah()`` creates a target which encapsulates
+header files generation. E.g.
+
+.. code-block:: cmake
+
+  create_javah(TARGET target_headers
+    CLASSES org.cmake.HelloWorld
+    CLASSPATH hello.jar
+  )
+
+Both signatures share same options.
+
+``CLASSES <class>...``
+  Specifies Java classes used to generate headers.
+
+``CLASSPATH <classpath>...``
+  Specifies various paths to look up classes. Here .class files, jar files or
+  targets created by command add_jar can be used.
+
+``DEPENDS <depend>...``
+  Targets on which the javah target depends.
+
+``OUTPUT_NAME <path>``
+  Concatenates the resulting header files for all the classes listed by option
+  ``CLASSES`` into ``<path>``.  Same behavior as option ``-o`` of javah tool.
+
+``OUTPUT_DIR <path>``
+  Sets the directory where the header files will be generated.  Same behavior
+  as option ``-d`` of javah tool.  If not specified,
+  :variable:`CMAKE_CURRENT_BINARY_DIR` is used as the output directory.

+UseSWIG
+-------
+
+This file provides support for ``SWIG``. It is assumed that :module:`FindSWIG`
+module has already been loaded.
+
+Defines the following command for use with ``SWIG``:
+
+.. command:: swig_add_library
+
+  Define swig module with given name and specified language::
+
+    swig_add_library(<name>
+                     [TYPE <SHARED|MODULE|STATIC|USE_BUILD_SHARED_LIBS>]
+                     LANGUAGE <language>
+                     [NO_PROXY]
+                     [OUTPUT_DIR <directory>]
+                     [OUTFILE_DIR <directory>]
+                     SOURCES <file>...
+                    )
+
+  Targets created with the ``swig_add_library`` command have the same
+  capabilities as targets created with the :command:`add_library` command, so
+  those targets can be used with any command expecting a target (e.g.
+  :command:`target_link_libraries`).
+
+  .. note::
+
+    This command creates a target with the specified ``<name>`` when
+    policy :policy:`CMP0078` is set to ``NEW``.  Otherwise, the legacy
+    behavior will choose a different target name and store it in the
+    ``SWIG_MODULE_<name>_REAL_NAME`` variable.
+
+  .. note::
+
+    For multi-config generators, this module does not support
+    configuration-specific files generated by ``SWIG``. All build
+    configurations must result in the same generated source file.
+
+  ``TYPE``
+    ``SHARED``, ``MODULE`` and ``STATIC`` have the same semantic as for the
+    :command:`add_library` command. If ``USE_BUILD_SHARED_LIBS`` is specified,
+    the library type will be ``STATIC`` or ``SHARED`` based on whether the
+    current value of the :variable:`BUILD_SHARED_LIBS` variable is ``ON``. If
+    no type is specified, ``MODULE`` will be used.
+
+  ``LANGUAGE``
+    Specify the target language.
+
+  ``NO_PROXY``
+    Prevent the generation of the wrapper layer (swig ``-noproxy`` option).
+
+  ``OUTPUT_DIR``
+    Specify where to write the language specific files (swig ``-outdir``
+    option). If not given, the ``CMAKE_SWIG_OUTDIR`` variable will be used.
+    If neither is specified, the default depends on the value of the
+    ``UseSWIG_MODULE_VERSION`` variable as follows:
+
+    * If ``UseSWIG_MODULE_VERSION`` is 1 or is undefined, output is written to
+      the :variable:`CMAKE_CURRENT_BINARY_DIR` directory.
+    * If ``UseSWIG_MODULE_VERSION`` is 2, a dedicated directory will be used.
+      The path of this directory can be retrieved from the
+      ``SWIG_SUPPORT_FILES_DIRECTORY`` target property.
+
+  ``OUTFILE_DIR``
+    Specify an output directory name where the generated source file will be
+    placed (swig -o option). If not specified, the ``SWIG_OUTFILE_DIR`` variable
+    will be used. If neither is specified, ``OUTPUT_DIR`` or
+    ``CMAKE_SWIG_OUTDIR`` is used instead.
+
+  ``SOURCES``
+    List of sources for the library. Files with extension ``.i`` will be
+    identified as sources for the ``SWIG`` tool. Other files will be handled in
+    the standard way. This behavior can be overriden by specifying the variable
+    ``SWIG_SOURCE_FILE_EXTENSIONS``.
+
+  .. note::
+
+    If ``UseSWIG_MODULE_VERSION`` is set to 2, it is **strongly** recommended
+    to use a dedicated directory unique to the target when either the
+    ``OUTPUT_DIR`` option or the ``CMAKE_SWIG_OUTDIR`` variable are specified.
+    The output directory contents are erased as part of the target build, so
+    to prevent interference between targets or losing other important files,
+    each target should have its own dedicated output directory.
+
+.. command:: swig_link_libraries
+
+  Link libraries to swig module::
+
+    swig_link_libraries(<name> <item>...)
+
+  This command has same capabilities as :command:`target_link_libraries`
+  command.
+
+  .. note::
+
+    If variable ``UseSWIG_TARGET_NAME_PREFERENCE`` is set to ``STANDARD``, this
+    command is deprecated and :command:`target_link_libraries` command must be
+    used instead.
+
+Source file properties on module files **must** be set before the invocation
+of the ``swig_add_library`` command to specify special behavior of SWIG and
+ensure generated files will receive the required settings.
+
+``CPLUSPLUS``
+  Call SWIG in c++ mode.  For example:
+
+  .. code-block:: cmake
+
+    set_property(SOURCE mymod.i PROPERTY CPLUSPLUS ON)
+    swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
+
+``INCLUDE_DIRECTORIES``, ``COMPILE_DEFINITIONS`` and ``COMPILE_OPTIONS``
+  Add custom flags to SWIG compiler and have same semantic as properties
+  :prop_sf:`INCLUDE_DIRECTORIES`, :prop_sf:`COMPILE_DEFINITIONS` and
+  :prop_sf:`COMPILE_OPTIONS`.
+
+``USE_TARGET_INCLUDE_DIRECTORIES``
+  If set to ``TRUE``, contents of target property
+  :prop_tgt:`INCLUDE_DIRECTORIES` will be forwarded to ``SWIG`` compiler.
+  If set to ``FALSE`` target property :prop_tgt:`INCLUDE_DIRECTORIES` will be
+  ignored. If not set, target property ``SWIG_USE_TARGET_INCLUDE_DIRECTORIES``
+  will be considered.
+
+``GENERATED_INCLUDE_DIRECTORIES``, ``GENERATED_COMPILE_DEFINITIONS`` and ``GENERATED_COMPILE_OPTIONS``
+  Add custom flags to the C/C++ generated source. They will fill, respectively,
+  properties :prop_sf:`INCLUDE_DIRECTORIES`, :prop_sf:`COMPILE_DEFINITIONS` and
+  :prop_sf:`COMPILE_OPTIONS` of generated C/C++ file.
+
+``DEPENDS``
+  Specify additional dependencies to the source file.
+
+``SWIG_MODULE_NAME``
+  Specify the actual import name of the module in the target language.
+  This is required if it cannot be scanned automatically from source
+  or different from the module file basename.  For example:
+
+  .. code-block:: cmake
+
+    set_property(SOURCE mymod.i PROPERTY SWIG_MODULE_NAME mymod_realname)
+
+  .. note::
+
+    If policy :policy:`CMP0086` is set to ``NEW``, ``-module <module_name>``
+    is passed to ``SWIG`` compiler.
+
+Target library properties can be set to apply same configuration to all SWIG
+input files.
+
+``SWIG_INCLUDE_DIRECTORIES``, ``SWIG_COMPILE_DEFINITIONS`` and ``SWIG_COMPILE_OPTIONS``
+  These properties will be applied to all SWIG input files and have same
+  semantic as target properties :prop_tgt:`INCLUDE_DIRECTORIES`,
+  :prop_tgt:`COMPILE_DEFINITIONS` and :prop_tgt:`COMPILE_OPTIONS`.
+
+  .. code-block:: cmake
+
+    set (UseSWIG_TARGET_NAME_PREFERENCE STANDARD)
+    swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
+    set_property(TARGET mymod PROPERTY SWIG_COMPILE_DEFINITIONS MY_DEF1 MY_DEF2)
+    set_property(TARGET mymod PROPERTY SWIG_COMPILE_OPTIONS -bla -blb)
+
+``SWIG_USE_TARGET_INCLUDE_DIRECTORIES``
+  If set to ``TRUE``, contents of target property
+  :prop_tgt:`INCLUDE_DIRECTORIES` will be forwarded to ``SWIG`` compiler.
+  If set to ``FALSE`` or not defined, target property
+  :prop_tgt:`INCLUDE_DIRECTORIES` will be ignored. This behavior can be
+  overridden by specifying source property ``USE_TARGET_INCLUDE_DIRECTORIES``.
+
+``SWIG_GENERATED_INCLUDE_DIRECTORIES``, ``SWIG_GENERATED_COMPILE_DEFINITIONS`` and ``SWIG_GENERATED_COMPILE_OPTIONS``
+  These properties will populate, respectively, properties
+  :prop_sf:`INCLUDE_DIRECTORIES`, :prop_sf:`COMPILE_DEFINITIONS` and
+  :prop_sf:`COMPILE_FLAGS` of all generated C/C++ files.
+
+``SWIG_DEPENDS``
+  Add dependencies to all SWIG input files.
+
+The following target properties are output properties and can be used to get
+information about support files generated by ``SWIG`` interface compilation.
+
+``SWIG_SUPPORT_FILES``
+  This output property list of wrapper files generated during SWIG compilation.
+
+  .. code-block:: cmake
+
+    set (UseSWIG_TARGET_NAME_PREFERENCE STANDARD)
+    swig_add_library(mymod LANGUAGE python SOURCES mymod.i)
+    get_property(support_files TARGET mymod PROPERTY SWIG_SUPPORT_FILES)
+
+  .. note::
+
+    Only most principal support files are listed. In case some advanced
+    features of ``SWIG`` are used (for example ``%template``), associated
+    support files may not be listed. Prefer to use the
+    ``SWIG_SUPPORT_FILES_DIRECTORY`` property to handle support files.
+
+``SWIG_SUPPORT_FILES_DIRECTORY``
+  This output property specifies the directory where support files will be
+  generated.
+
+Some variables can be set to customize the behavior of ``swig_add_library``
+as well as ``SWIG``:
+
+``UseSWIG_MODULE_VERSION``
+  Specify different behaviors for ``UseSWIG`` module.
+
+  * Set to 1 or undefined: Legacy behavior is applied.
+  * Set to 2: A new strategy is applied regarding support files: the output
+    directory of support files is erased before ``SWIG`` interface compilation.
+
+``CMAKE_SWIG_FLAGS``
+  Add flags to all swig calls.
+
+``CMAKE_SWIG_OUTDIR``
+  Specify where to write the language specific files (swig ``-outdir`` option).
+
+``SWIG_OUTFILE_DIR``
+  Specify an output directory name where the generated source file will be
+  placed.  If not specified, ``CMAKE_SWIG_OUTDIR`` is used.
+
+``SWIG_MODULE_<name>_EXTRA_DEPS``
+  Specify extra dependencies for the generated module for ``<name>``.
+
+``SWIG_SOURCE_FILE_EXTENSIONS``
+  Specify a list of source file extensions to override the default
+  behavior of considering only ``.i`` files as sources for the ``SWIG``
+  tool. For example:
+
+  .. code-block:: cmake
+
+    set(SWIG_SOURCE_FILE_EXTENSIONS ".i" ".swg")

-#
-# The ``write_compiler_detection_header`` function generates the

-#
-# By default, all content is written directly to the ``<file>``.  The

-# .. code-block:: cmake
-#
-#    write_compiler_detection_header(
-#      FILE climbingstats_compiler_detection.h

-#
-# Feature Test Macros
-# ===================
-#
-# For each compiler, a preprocessor macro is generated matching
-# ``<PREFIX>_COMPILER_IS_<compiler>`` which has the content either ``0``
-# or ``1``, depending on the compiler in use. Preprocessor macros for
-# compiler version components are generated matching
-# ``<PREFIX>_COMPILER_VERSION_MAJOR`` ``<PREFIX>_COMPILER_VERSION_MINOR``
-# and ``<PREFIX>_COMPILER_VERSION_PATCH`` containing decimal values
-# for the corresponding compiler version components, if defined.
-#
-# A preprocessor test is generated based on the compiler version
-# denoting whether each feature is enabled.  A preprocessor macro
-# matching ``<PREFIX>_COMPILER_<FEATURE>``, where ``<FEATURE>`` is the
-# upper-case ``<feature>`` name, is generated to contain the value
-# ``0`` or ``1`` depending on whether the compiler in use supports the
-# feature:
-#
-# .. code-block:: cmake
-#
-#    write_compiler_detection_header(
-#      FILE climbingstats_compiler_detection.h
-#      PREFIX ClimbingStats
-#      COMPILERS GNU Clang AppleClang MSVC Intel
-#      FEATURES cxx_variadic_templates
-#    )
-#
-# .. code-block:: c++
-#
-#    #if ClimbingStats_COMPILER_CXX_VARIADIC_TEMPLATES
-#    template<typename... T>
-#    void someInterface(T t...) { /* ... */ }
-#    #else
-#    // Compatibility versions
-#    template<typename T1>
-#    void someInterface(T1 t1) { /* ... */ }
-#    template<typename T1, typename T2>
-#    void someInterface(T1 t1, T2 t2) { /* ... */ }
-#    template<typename T1, typename T2, typename T3>
-#    void someInterface(T1 t1, T2 t2, T3 t3) { /* ... */ }
-#    #endif
-#
-# Symbol Macros
-# =============
-#
-# Some additional symbol-defines are created for particular features for
-# use as symbols which may be conditionally defined empty:
-#
-# .. code-block:: c++
-#
-#    class MyClass ClimbingStats_FINAL
-#    {
-#        ClimbingStats_CONSTEXPR int someInterface() { return 42; }
-#    };
-#
-# The ``ClimbingStats_FINAL`` macro will expand to ``final`` if the
-# compiler (and its flags) support the ``cxx_final`` feature, and the
-# ``ClimbingStats_CONSTEXPR`` macro will expand to ``constexpr``
-# if ``cxx_constexpr`` is supported.
-#
-# The following features generate corresponding symbol defines:
-#
-# ========================== =================================== =================

-# ========================== =================================== =================
-#
-# Compatibility Implementation Macros
-# ===================================
-#
-# Some features are suitable for wrapping in a macro with a backward
-# compatibility implementation if the compiler does not support the feature.
-#
-# When the ``cxx_static_assert`` feature is not provided by the compiler,
-# a compatibility implementation is available via the
-# ``<PREFIX>_STATIC_ASSERT(COND)`` and
-# ``<PREFIX>_STATIC_ASSERT_MSG(COND, MSG)`` function-like macros. The macros
-# expand to ``static_assert`` where that compiler feature is available, and
-# to a compatibility implementation otherwise. In the first form, the
-# condition is stringified in the message field of ``static_assert``.  In
-# the second form, the message ``MSG`` is passed to the message field of
-# ``static_assert``, or ignored if using the backward compatibility
-# implementation.
-#
-# The ``cxx_attribute_deprecated`` feature provides a macro definition
-# ``<PREFIX>_DEPRECATED``, which expands to either the standard
-# ``[[deprecated]]`` attribute or a compiler-specific decorator such
-# as ``__attribute__((__deprecated__))`` used by GNU compilers.
-#
-# The ``cxx_alignas`` feature provides a macro definition
-# ``<PREFIX>_ALIGNAS`` which expands to either the standard ``alignas``
-# decorator or a compiler-specific decorator such as
-# ``__attribute__ ((__aligned__))`` used by GNU compilers.
-#
-# The ``cxx_alignof`` feature provides a macro definition
-# ``<PREFIX>_ALIGNOF`` which expands to either the standard ``alignof``
-# decorator or a compiler-specific decorator such as ``__alignof__``
-# used by GNU compilers.

+             [ALLOW_UNKNOWN_COMPILERS]
+             [ALLOW_UNKNOWN_COMPILER_VERSIONS]
+   )
+
+This generates the file ``<file>`` with macros which all have the prefix

+
+By default, all content is written directly to the ``<file>``.  The

+     DESTINATION include
+   )
+   install(FILES
+     ${support_files}
+     DESTINATION include/compilers
+   )
+
+
+``VERSION`` may be used to specify the API version to be generated.
+Future versions of CMake may introduce alternative APIs.  A given
+API is selected by any ``<version>`` value greater than or equal
+to the version of CMake that introduced the given API and less

+(As of CMake version |release| there is only one API version.)
+
+``PROLOG`` may be specified as text content to write at the start of the
+header. ``EPILOG`` may be specified as text content to write at the end
+of the header
+
+At least one ``<compiler>`` and one ``<feature>`` must be listed.  Compilers
+which are known to CMake, but not specified are detected and a preprocessor
+``#error`` is generated for them.  A preprocessor macro matching
+``<PREFIX>_COMPILER_IS_<compiler>`` is generated for each compiler
+known to CMake to contain the value ``0`` or ``1``.
+
+Possible compiler identifiers are documented with the
+:variable:`CMAKE_<LANG>_COMPILER_ID` variable.
+Available features in this version of CMake are listed in the

+The ``{c,cxx}_std_*`` meta-features are ignored if requested.
+
+See the :manual:`cmake-compile-features(7)` manual for information on
+compile features.
+
+``BARE_FEATURES`` will define the compatibility macros with the name used in
+newer versions of the language standard, so the code can use the new feature
+name unconditionally.
+
+``ALLOW_UNKNOWN_COMPILERS`` and ``ALLOW_UNKNOWN_COMPILER_VERSIONS`` cause
+the module to generate conditions that treat unknown compilers as simply
+lacking all features.  Without these options the default behavior is to
+generate a ``#error`` for unknown compilers and versions.
+
+Feature Test Macros
+===================
+
+For each compiler, a preprocessor macro is generated matching
+``<PREFIX>_COMPILER_IS_<compiler>`` which has the content either ``0``
+or ``1``, depending on the compiler in use. Preprocessor macros for
+compiler version components are generated matching
+``<PREFIX>_COMPILER_VERSION_MAJOR`` ``<PREFIX>_COMPILER_VERSION_MINOR``
+and ``<PREFIX>_COMPILER_VERSION_PATCH`` containing decimal values
+for the corresponding compiler version components, if defined.
+
+A preprocessor test is generated based on the compiler version
+denoting whether each feature is enabled.  A preprocessor macro
+matching ``<PREFIX>_COMPILER_<FEATURE>``, where ``<FEATURE>`` is the
+upper-case ``<feature>`` name, is generated to contain the value
+``0`` or ``1`` depending on whether the compiler in use supports the
+feature:
+
+.. code-block:: cmake
+
+   write_compiler_detection_header(
+     FILE climbingstats_compiler_detection.h
+     PREFIX ClimbingStats
+     COMPILERS GNU Clang AppleClang MSVC Intel
+     FEATURES cxx_variadic_templates
+   )
+
+.. code-block:: c++
+
+   #if ClimbingStats_COMPILER_CXX_VARIADIC_TEMPLATES
+   template<typename... T>
+   void someInterface(T t...) { /* ... */ }
+   #else
+   // Compatibility versions
+   template<typename T1>
+   void someInterface(T1 t1) { /* ... */ }
+   template<typename T1, typename T2>
+   void someInterface(T1 t1, T2 t2) { /* ... */ }
+   template<typename T1, typename T2, typename T3>
+   void someInterface(T1 t1, T2 t2, T3 t3) { /* ... */ }
+   #endif
+
+Symbol Macros
+=============
+
+Some additional symbol-defines are created for particular features for
+use as symbols which may be conditionally defined empty:
+
+.. code-block:: c++
+
+   class MyClass ClimbingStats_FINAL
+   {
+       ClimbingStats_CONSTEXPR int someInterface() { return 42; }
+   };
+
+The ``ClimbingStats_FINAL`` macro will expand to ``final`` if the
+compiler (and its flags) support the ``cxx_final`` feature, and the
+``ClimbingStats_CONSTEXPR`` macro will expand to ``constexpr``
+if ``cxx_constexpr`` is supported.
+
+If ``BARE_FEATURES cxx_final`` was given as argument the ``final`` keyword
+will be defined for old compilers, too.
+
+The following features generate corresponding symbol defines and if they
+are available as ``BARE_FEATURES``:
+

+========================== =================================== ================= ======
+
+Compatibility Implementation Macros
+===================================
+
+Some features are suitable for wrapping in a macro with a backward
+compatibility implementation if the compiler does not support the feature.
+
+When the ``cxx_static_assert`` feature is not provided by the compiler,
+a compatibility implementation is available via the
+``<PREFIX>_STATIC_ASSERT(COND)`` and
+``<PREFIX>_STATIC_ASSERT_MSG(COND, MSG)`` function-like macros. The macros
+expand to ``static_assert`` where that compiler feature is available, and
+to a compatibility implementation otherwise. In the first form, the
+condition is stringified in the message field of ``static_assert``.  In
+the second form, the message ``MSG`` is passed to the message field of
+``static_assert``, or ignored if using the backward compatibility
+implementation.
+
+The ``cxx_attribute_deprecated`` feature provides a macro definition
+``<PREFIX>_DEPRECATED``, which expands to either the standard
+``[[deprecated]]`` attribute or a compiler-specific decorator such
+as ``__attribute__((__deprecated__))`` used by GNU compilers.
+
+The ``cxx_alignas`` feature provides a macro definition
+``<PREFIX>_ALIGNAS`` which expands to either the standard ``alignas``
+decorator or a compiler-specific decorator such as
+``__attribute__ ((__aligned__))`` used by GNU compilers.
+
+The ``cxx_alignof`` feature provides a macro definition
+``<PREFIX>_ALIGNOF`` which expands to either the standard ``alignof``
+decorator or a compiler-specific decorator such as ``__alignof__``
+used by GNU compilers.

+ *
  * Extension (Axel 2006-03-15)
  *    As soon as an object file contains an /EXPORT directive (which
  *    is generated by the compiler when a symbol is declared as
- *    declspec(dllexport)) no to-be-exported symbols are printed,
+ *    __declspec(dllexport) no to-be-exported symbols are printed,
  *    as the linker will see these directives, and if those directives
  *    are present we only export selectively (i.e. we trust the
  *    programmer).

-* Corrections (Valery Fine 23/02/98):
-*
-*           The "(vector) deleting destructor" MUST not be exported
-*           To recognize it the following test are introduced:

-*  "@@QAEPAXI@Z"  vector deleting dtor
-*  "AEPAXI@Z"     vector deleting dtor with thunk adjustor
-*   ======================================
-* Corrections (Valery Fine 12/02/97):
-*
-*    It created a wrong EXPORTS for the global pointers and constants.
-*    The Section Header has been involved to discover the missing information
-*    Now the pointers are correctly supplied  supplied with "DATA" descriptor
-*        the constants  with no extra descriptor.
-*
-* Corrections (Valery Fine 16/09/96):
-*
-*     It didn't work for C++ code with global variables and class definitons
-*     The DumpExternalObject function has been introduced to generate .DEF file

+ * Upon success, the function returns CURLSSLSET_OK.

+ * If the specified SSL backend is not available, the function returns

+         IPv4 address, for example).
+
+         It's also possible that the other request could always just take
+         longer because it needs more time or only the second DNS server can
+         fulfill it successfully.  But, to align with the philosophy of Happy
+         Eyeballs, we don't want to wait _too_ long or users will think
+         requests are slow when IPv6 lookups don't actually work (but IPv4 ones
+         do).
+
+         So, now that we have a usable answer (some IPv4 addresses, some IPv6
+         addresses, or "no such domain"), we start a timeout for the remaining
+         pending responses.  Even though it is typical that this resolved
+         request came back quickly, that needn't be the case.  It might be that
+         this completing request didn't get a result from the first DNS server
+         or even the first round of the whole DNS server pool.  So it could
+         already be quite some time after we issued the DNS queries in the
+         first place.  Without modifying c-ares, we can't know exactly where in
+         its retry cycle we are.  We could guess based on how much time has
+         gone by, but it doesn't really matter.  Happy Eyeballs tells us that,
+         given usable information in hand, we simply don't want to wait "too
+         much longer" after we get a result.
+
+         We simply wait an additional amount of time equal to the default
+         c-ares query timeout.  That is enough time for a typical parallel
+         response to arrive without being "too long".  Even on a network
+         where one of the two types of queries is failing or timing out
+         constantly, this will usually mean we wait a total of the default
+         c-ares timeout (5 seconds) plus the round trip time for the successful
+         request, which seems bearable.  The downside is that c-ares might race
+         with us to issue one more retry just before we give up, but it seems
+         better to "waste" that request instead of trying to guess the perfect
+         timeout to prevent it.  After all, we don't even know where in the
+         c-ares retry cycle each request is.

-* - compute page index: pageIndex = itemIndex / itemsPerPage
-* - look-up item in page: pages_[pageIndex][itemIndex % itemsPerPage]
-*
-* Insertion is amortized constant time (only the array containing the index of
