+  will result in undefined behavior.
+
+``DIRECTORIES <directories>``
+  List of additional directories to search for dependencies. On Linux
+  platforms, these directories are searched if the dependency is not found in
+  any of the other usual paths. If it is found in such a directory, a warning
+  is issued, because it means that the file is incomplete (it does not list all
+  of the directories that contain its dependencies). On Windows platforms,
+  these directories are searched if the dependency is not found in any of the
+  other search paths, but no warning is issued, because searching other paths
+  is a normal part of Windows dependency resolution. On Apple platforms, this
+  argument has no effect.
+
+``BUNDLE_EXECUTABLE <bundle_executable_file>``
+  Executable to treat as the "bundle executable" when resolving libraries. On
+  Apple platforms, this argument determines the value of ``@executable_path``
+  when recursively resolving libraries for ``LIBRARIES`` and ``MODULES`` files.
+  It has no effect on ``EXECUTABLES`` files. On other platforms, it has no
+  effect. This is typically (but not always) one of the executables in the
+  ``EXECUTABLES`` argument which designates the "main" executable of the
+  package.
+
+The following arguments specify filters for including or excluding libraries to
+be resolved. See below for a full description of how they work.
+
+``PRE_INCLUDE_REGEXES <regexes>``
+  List of pre-include regexes through which to filter the names of
+  not-yet-resolved dependencies.
+
+``PRE_EXCLUDE_REGEXES <regexes>``
+  List of pre-exclude regexes through which to filter the names of
+  not-yet-resolved dependencies.
+
+``POST_INCLUDE_REGEXES <regexes>``
+  List of post-include regexes through which to filter the names of resolved
+  dependencies.
+
+``POST_EXCLUDE_REGEXES <regexes>``
+  List of post-exclude regexes through which to filter the names of resolved
+  dependencies.
+
+These arguments can be used to blacklist unwanted system libraries when
+resolving the dependencies, or to whitelist libraries from a specific
+directory. The filtering works as follows:
+
+1. If the not-yet-resolved dependency matches any of the
+   ``PRE_INCLUDE_REGEXES``, steps 2 and 3 are skipped, and the dependency
+   resolution proceeds to step 4.
+2. If the not-yet-resolved dependency matches any of the
+   ``PRE_EXCLUDE_REGEXES``, dependency resolution stops for that dependency.
+3. Otherwise, dependency resolution proceeds.
+4. ``file(GET_RUNTIME_DEPENDENCIES)`` searches for the dependency according to
+   the linking rules of the platform (see below).
+5. If the dependency is found, and its full path matches one of the
+   ``POST_INCLUDE_REGEXES``, the full path is added to the resolved
+   dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)`` recursively resolves
+   that library's own dependencies. Otherwise, resolution proceeds to step 6.
+6. If the dependency is found, but its full path matches one of the
+   ``POST_EXCLUDE_REGEXES``, it is not added to the resolved dependencies, and
+   dependency resolution stops for that dependency.
+7. If the dependency is found, and its full path does not match either
+   ``POST_INCLUDE_REGEXES`` or ``POST_EXCLUDE_REGEXES``, the full path is added
+   to the resolved dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)``
+   recursively resolves that library's own dependencies.
+
+Different platforms have different rules for how dependencies are resolved.
+These specifics are described here.
+
+On Linux platforms, library resolution works as follows:
+
+1. If the depending file does not have any ``RUNPATH`` entries, and the library
+   exists in one of the depending file's ``RPATH`` entries, or its parents', in
+   that order, the dependency is resolved to that file.
+2. Otherwise, if the depending file has any ``RUNPATH`` entries, and the
+   library exists in one of those entries, the dependency is resolved to that
+   file.
+3. Otherwise, if the library exists in one of the directories listed by
+   ``ldconfig``, the dependency is resolved to that file.
+4. Otherwise, if the library exists in one of the ``DIRECTORIES`` entries, the
+   dependency is resolved to that file. In this case, a warning is issued,
+   because finding a file in one of the ``DIRECTORIES`` means that the
+   depending file is not complete (it does not list all the directories from
+   which it pulls dependencies).
+5. Otherwise, the dependency is unresolved.
+
+On Windows platforms, library resolution works as follows:
+
+1. The dependent DLL name is converted to lowercase. Windows DLL names are
+   case-insensitive, and some linkers mangle the case of the DLL dependency
+   names. However, this makes it more difficult for ``PRE_INCLUDE_REGEXES``,
+   ``PRE_EXCLUDE_REGEXES``, ``POST_INCLUDE_REGEXES``, and
+   ``POST_EXCLUDE_REGEXES`` to properly filter DLL names - every regex would
+   have to check for both uppercase and lowercase letters. For example:
+
+   .. code-block:: cmake
+
+     file(GET_RUNTIME_DEPENDENCIES
+       # ...
+       PRE_INCLUDE_REGEXES "^[Mm][Yy][Ll][Ii][Bb][Rr][Aa][Rr][Yy]\\.[Dd][Ll][Ll]$"
+       )
+
+   Converting the DLL name to lowercase allows the regexes to only match
+   lowercase names, thus simplifying the regex. For example:
+
+   .. code-block:: cmake
+
+     file(GET_RUNTIME_DEPENDENCIES
+       # ...
+       PRE_INCLUDE_REGEXES "^mylibrary\\.dll$"
+       )
+
+   This regex will match ``mylibrary.dll`` regardless of how it is cased,
+   either on disk or in the depending file. (For example, it will match
+   ``mylibrary.dll``, ``MyLibrary.dll``, and ``MYLIBRARY.DLL``.)
+
+   Please note that the directory portion of any resolved DLLs retains its
+   casing and is not converted to lowercase. Only the filename portion is
+   converted.
+
+2. (**Not yet implemented**) If the depending file is a Windows Store app, and
+   the dependency is listed as a dependency in the application's package
+   manifest, the dependency is resolved to that file.
+3. Otherwise, if the library exists in the same directory as the depending
+   file, the dependency is resolved to that file.
+4. Otherwise, if the library exists in either the operating system's
+   ``system32`` directory or the ``Windows`` directory, in that order, the
+   dependency is resolved to that file.
+5. Otherwise, if the library exists in one of the directories specified by
+   ``DIRECTORIES``, in the order they are listed, the dependency is resolved to
+   that file. In this case, a warning is not issued, because searching other
+   directories is a normal part of Windows library resolution.
+6. Otherwise, the dependency is unresolved.
+
+On Apple platforms, library resolution works as follows:
+
+1. If the dependency starts with ``@executable_path/``, and an ``EXECUTABLES``
+   argument is in the process of being resolved, and replacing
+   ``@executable_path/`` with the directory of the executable yields an
+   existing file, the dependency is resolved to that file.
+2. Otherwise, if the dependency starts with ``@executable_path/``, and there is
+   a ``BUNDLE_EXECUTABLE`` argument, and replacing ``@executable_path/`` with
+   the directory of the bundle executable yields an existing file, the
+   dependency is resolved to that file.
+3. Otherwise, if the dependency starts with ``@loader_path/``, and replacing
+   ``@loader_path/`` with the directory of the depending file yields an
+   existing file, the dependency is resolved to that file.
+4. Otherwise, if the dependency starts with ``@rpath/``, and replacing
+   ``@rpath/`` with one of the ``RPATH`` entries of the depending file yields
+   an existing file, the dependency is resolved to that file. Note that
+   ``RPATH`` entries that start with ``@executable_path/`` or ``@loader_path/``
+   also have these items replaced with the appropriate path.
+5. Otherwise, if the dependency is an absolute file that exists, the dependency
+   is resolved to that file.
+6. Otherwise, the dependency is unresolved.
+
+This function accepts several variables that determine which tool is used for
+dependency resolution:
+
+.. variable:: CMAKE_GET_RUNTIME_DEPENDENCIES_PLATFORM
+
+  Determines which operating system and executable format the files are built
+  for. This could be one of several values:
+
+  * ``linux+elf``
+  * ``windows+pe``
+  * ``macos+macho``
+
+  If this variable is not specified, it is determined automatically by system
+  introspection.
+
+.. variable:: CMAKE_GET_RUNTIME_DEPENDENCIES_TOOL
+

+target_precompile_headers
+-------------------------
+
+Add a list of header files to precompile.
+
+Precompiling header files can speed up compilation by creating a partially
+processed version of some header files, and then using that version during
+compilations rather than repeatedly parsing the original headers.
+
+Main Form
+^^^^^^^^^
+
+.. code-block:: cmake
+
+  target_precompile_headers(<target>
+    <INTERFACE|PUBLIC|PRIVATE> [header1...]
+    [<INTERFACE|PUBLIC|PRIVATE> [header2...] ...])
+
+The command adds header files to the :prop_tgt:`PRECOMPILE_HEADERS` and/or
+:prop_tgt:`INTERFACE_PRECOMPILE_HEADERS` target properties of ``<target>``.
+The named ``<target>`` must have been created by a command such as
+:command:`add_executable` or :command:`add_library` and must not be an
+:ref:`ALIAS target <Alias Targets>`.
+
+The ``INTERFACE``, ``PUBLIC`` and ``PRIVATE`` keywords are required to
+specify the scope of the following arguments.  ``PRIVATE`` and ``PUBLIC``
+items will populate the :prop_tgt:`PRECOMPILE_HEADERS` property of
+``<target>``.  ``PUBLIC`` and ``INTERFACE`` items will populate the
+:prop_tgt:`INTERFACE_PRECOMPILE_HEADERS` property of ``<target>``
+(:ref:`IMPORTED targets <Imported Targets>` only support ``INTERFACE`` items).
+Repeated calls for the same ``<target>`` will append items in the order called.
+
+Projects should generally avoid using ``PUBLIC`` or ``INTERFACE`` for targets
+that will be :ref:`exported <install(EXPORT)>`, or they should at least use
+the ``$<BUILD_INTERFACE:...>`` generator expression to prevent precompile
+headers from appearing in an installed exported target.  Consumers of a target
+should typically be in control of what precompile headers they use, not have
+precompile headers forced on them by the targets being consumed (since
+precompile headers are not typically usage requirements).  A notable exception
+to this is where an :ref:`interface library <Interface Libraries>` is created
+to define a commonly used set of precompile headers in one place and then other
+targets link to that interface library privately.  In this case, the interface
+library exists specifically to propagate the precompile headers to its
+consumers and the consumer is effectively still in control, since it decides
+whether to link to the interface library or not.
+
+The list of header files is used to generate a header file named
+``cmake_pch.h|xx`` which is used to generate the precompiled header file
+(``.pch``, ``.gch``, ``.pchi``) artifact.  The ``cmake_pch.h|xx`` header
+file will be force included (``-include`` for GCC, ``/FI`` for MSVC) to
+all source files, so sources do not need to have ``#include "pch.h"``.
+
+Header file names specified with angle brackets (e.g. ``<unordered_map>``) or
+explicit double quotes (escaped for the :manual:`cmake-language(7)`,
+e.g. ``[["other_header.h"]]``) will be treated as is, and include directories
+must be available for the compiler to find them.  Other header file names
+(e.g. ``project_header.h``) are interpreted as being relative to the current
+source directory (e.g. :variable:`CMAKE_CURRENT_SOURCE_DIR`) and will be
+included by absolute path.
+
+Arguments to ``target_precompile_headers()`` may use "generator expressions"
+with the syntax ``$<...>``.
+See the :manual:`cmake-generator-expressions(7)` manual for available
+expressions.  See the :manual:`cmake-compile-features(7)` manual for
+information on compile features and a list of supported compilers.
+The ``$<COMPILE_LANGUAGE:...>`` generator expression is particularly
+useful for specifying a language-specific header to precompile for
+only one language (e.g. ``CXX`` and not ``C``).  For example:
+
+.. code-block:: cmake
+
+  target_precompile_headers(myTarget
+    PUBLIC
+      project_header.h
+      "$<$<COMPILE_LANGUAGE:CXX>:cxx_only.h>"
+    PRIVATE
+      [["other_header.h"]]
+      <unordered_map>
+  )
+
+When specifying angle brackets inside a :manual:`generator expression
+<cmake-generator-expressions(7)>`, be sure to encode the closing ``>``
+as ``$<ANGLE-R>``.  For example:
+
+.. code-block:: cmake
+
+  target_precompile_headers(mylib PRIVATE
+    "$<$<COMPILE_LANGUAGE:C>:<stddef.h$<ANGLE-R>>"
+    "$<$<COMPILE_LANGUAGE:CXX>:<cstddef$<ANGLE-R>>"
+  )
+
+
+Reusing Precompile Headers
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The command also supports a second signature which can be used to specify that
+one target re-uses a precompiled header file artefact from another target
+instead of generating its own:
+
+.. code-block:: cmake
+
+  target_precompile_headers(<target> REUSE_FROM <other_target>)
+
+This form sets the :prop_tgt:`PRECOMPILE_HEADERS_REUSE_FROM` property to
+``<other_target>`` and adds a dependency such that ``<target>`` will depend
+on ``<other_target>``.  CMake will halt with an error if the
+:prop_tgt:`PRECOMPILE_HEADERS` property of ``<target>`` is already set when
+the ``REUSE_FROM`` form is used.
+
+.. note::
+
+  The ``REUSE_FROM`` form requires the same set of compiler options,
+  compiler flags and compiler definitions for both ``<target>`` and
+  ``<other_target>``.  Some compilers (e.g. GCC) may issue a warning if the
+  precompiled header file cannot be used (``-Winvalid-pch``).
+
+See Also
+^^^^^^^^
+
+To disable precompile headers for specific targets, see the
+:prop_tgt:`DISABLE_PRECOMPILE_HEADERS` target property.
+
+To prevent precompile headers from being used when compiling a specific
+source file, see the :prop_sf:`SKIP_PRECOMPILE_HEADERS` source file property.

+CMake Tutorial
+**************
+
+.. only:: html
+
+   .. contents::
+
+The CMake tutorial provides a step-by-step guide that covers common build
+system issues that CMake helps address. Seeing how various topics all
+work together in an example project can be very helpful. The tutorial
+documentation and source code for examples can be found in the
+``Help/guide/tutorial`` directory of the CMake source code tree. Each step has
+its own subdirectory containing code that may be used as a starting point. The
+tutorial examples are progressive so that each step provides the complete
+solution for the previous step.
+
+A Basic Starting Point (Step 1)
+===============================
+
+The most basic project is an executable built from source code files.
+For simple projects, a three line ``CMakeLists.txt`` file is all that is
+required. This will be the starting point for our tutorial. Create a
+``CMakeLists.txt`` file in the ``Step1`` directory that looks like:
+
+.. code-block:: cmake
+
+  cmake_minimum_required(VERSION 3.10)
+
+  # set the project name
+  project(Tutorial)
+
+  # add the executable
+  add_executable(Tutorial tutorial.cxx)
+
+
+Note that this example uses lower case commands in the ``CMakeLists.txt`` file.
+Upper, lower, and mixed case commands are supported by CMake. The source
+code for ``tutorial.cxx`` is provided in the ``Step1`` directory and can be
+used to compute the square root of a number.
+
+Adding a Version Number and Configured Header File
+--------------------------------------------------
+
+The first feature we will add is to provide our executable and project with a
+version number. While we could do this exclusively in the source code, using
+``CMakeLists.txt`` provides more flexibility.
+
+First, modify the ``CMakeLists.txt`` file to set the version number.
+
+.. literalinclude:: Step2/CMakeLists.txt
+  :language: cmake
+  :end-before: # specify the C++ standard
+
+Then, configure a header file to pass the version number to the source
+code:
+
+.. literalinclude:: Step2/CMakeLists.txt
+  :language: cmake
+  :start-after: # to the source code
+  :end-before: # add the executable
+
+Since the configured file will be written into the binary tree, we
+must add that directory to the list of paths to search for include
+files. Add the following lines to the end of the ``CMakeLists.txt`` file:
+
+.. literalinclude:: Step2/CMakeLists.txt
+  :language: cmake
+  :start-after: # so that we will find TutorialConfig.h
+
+Using your favorite editor, create ``TutorialConfig.h.in`` in the source
+directory with the following contents:
+
+.. literalinclude:: Step2/TutorialConfig.h.in
+  :language: cmake
+
+When CMake configures this header file the values for
+``@Tutorial_VERSION_MAJOR@`` and ``@Tutorial_VERSION_MINOR@`` will be
+replaced.
+
+Next modify ``tutorial.cxx`` to include the configured header file,
+``TutorialConfig.h``.
+
+Finally, let's print out the version number by updating ``tutorial.cxx`` as
+follows:
+
+.. literalinclude:: Step2/tutorial.cxx
+  :language: c++
+  :start-after: {
+  :end-before: // convert input to double
+
+Specify the C++ Standard
+-------------------------
+
+Next let's add some C++11 features to our project by replacing ``atof`` with
+``std::stod`` in ``tutorial.cxx``.  At the same time, remove
+``#include <cstdlib>``.
+
+.. literalinclude:: Step2/tutorial.cxx
+  :language: c++
+  :start-after: // convert input to double
+  :end-before: // calculate square root
+
+We will need to explicitly state in the CMake code that it should use the
+correct flags. The easiest way to enable support for a specific C++ standard
+in CMake is by using the ``CMAKE_CXX_STANDARD`` variable. For this tutorial,
+set the ``CMAKE_CXX_STANDARD`` variable in the ``CMakeLists.txt`` file to 11
+and ``CMAKE_CXX_STANDARD_REQUIRED`` to True:
+
+.. literalinclude:: Step2/CMakeLists.txt
+  :language: cmake
+  :end-before: # configure a header file to pass some of the CMake settings
+
+Build and Test
+--------------
+
+Run **cmake** or **cmake-gui** to configure the project and then build it
+with your chosen build tool.
+
+For example, from the command line we could navigate to the
+``Help/guide/tutorial`` directory of the CMake source code tree and run the
+following commands:
+
+.. code-block:: console
+
+  mkdir Step1_build
+  cd Step1_build
+  cmake ../Step1
+  cmake --build .
+
+Navigate to the directory where Tutorial was built (likely the make directory
+or a Debug or Release build configuration subdirectory) and run these commands:
+
+.. code-block:: console
+
+  Tutorial 4294967296
+  Tutorial 10
+  Tutorial
+
+Adding a Library (Step 2)
+=========================
+
+Now we will add a library to our project. This library will contain our own
+implementation for computing the square root of a number. The executable can
+then use this library instead of the standard square root function provided by
+the compiler.
+
+For this tutorial we will put the library into a subdirectory
+called ``MathFunctions``. This directory already contains a header file,
+``MathFunctions.h``, and a source file ``mysqrt.cxx``. The source file has one
+function called ``mysqrt`` that provides similar functionality to the
+compiler's ``sqrt`` function.
+
+Add the following one line ``CMakeLists.txt`` file to the ``MathFunctions``
+directory:
+
+.. literalinclude:: Step3/MathFunctions/CMakeLists.txt
+  :language: cmake
+
+To make use of the new library we will add an ``add_subdirectory`` call in the
+top-level ``CMakeLists.txt`` file so that the library will get built. We add
+the new library to the executable, and add ``MathFunctions`` as an include
+directory so that the ``mqsqrt.h`` header file can be found. The last few lines
+of the top-level ``CMakeLists.txt`` file should now look like:
+
+.. code-block:: cmake
+
+        # add the MathFunctions library
+        add_subdirectory(MathFunctions)
+
+        # add the executable
+        add_executable(Tutorial tutorial.cxx)
+
+        target_link_libraries(Tutorial PUBLIC MathFunctions)
+
+        # add the binary tree to the search path for include files
+        # so that we will find TutorialConfig.h
+        target_include_directories(Tutorial PUBLIC
+                                  "${PROJECT_BINARY_DIR}"
+                                  "${PROJECT_SOURCE_DIR}/MathFunctions"
+                                  )
+
+Now let us make the MathFunctions library optional. While for the tutorial
+there really isn’t any need to do so, for larger projects this is a common
+occurrence. The first step is to add an option to the top-level
+``CMakeLists.txt`` file.
+
+.. literalinclude:: Step3/CMakeLists.txt
+  :language: cmake
+  :start-after: # should we use our own math functions
+  :end-before: # add the MathFunctions library
+
+This option will be displayed in the CMake GUI and ccmake with a default
+value of ON that can be changed by the user. This setting will be stored in
+the cache so that the user does not need to set the value each time they run
+CMake on a build directory.
+
+The next change is to make building and linking the MathFunctions library
+conditional. To do this we change the end of the top-level ``CMakeLists.txt``
+file to look like the following:
+
+.. literalinclude:: Step3/CMakeLists.txt
+  :language: cmake
+  :start-after: # add the MathFunctions library
+
+Note the use of the variable ``EXTRA_LIBS`` to collect up any optional
+libraries to later be linked into the executable. The variable
+``EXTRA_INCLUDES`` is used similarly for optional header files. This is a
+classic approach when dealing with many optional components, we will cover
+the modern approach in the next step.
+
+The corresponding changes to the source code are fairly straightforward. First,
+in ``tutorial.cxx``, include the ``MathFunctions.h`` header if we need it:
+
+.. literalinclude:: Step3/tutorial.cxx
+  :language: c++
+  :start-after: // should we include the MathFunctions header
+  :end-before: int main
+
+Then, in the same file, make ``USE_MYMATH`` control which square root
+function is used:
+
+.. literalinclude:: Step3/tutorial.cxx
+  :language: c++
+  :start-after: // which square root function should we use?
+  :end-before: std::cout << "The square root of
+
+Since the source code now requires ``USE_MYMATH`` we can add it to
+``TutorialConfig.h.in`` with the following line:
+
+.. literalinclude:: Step3/TutorialConfig.h.in
+  :language: c
+  :lines: 4
+
+**Exercise**: Why is it important that we configure ``TutorialConfig.h.in``
+after the option for ``USE_MYMATH``? What would happen if we inverted the two?
+
+Run **cmake** or **cmake-gui** to configure the project and then build it
+with your chosen build tool. Then run the built Tutorial executable.
+
+Use ccmake or the CMake GUI to update the value of ``USE_MYMATH``. Rebuild and
+run the tutorial again. Which function gives better results, sqrt or mysqrt?
+
+Adding Usage Requirements for Library (Step 3)
+==============================================
+
+Usage requirements allow for far better control over a library or executable's
+link and include line while also giving more control over the transitive
+property of targets inside CMake. The primary commands that leverage usage
+requirements are:
+
+  - ``target_compile_definitions``
+  - ``target_compile_options``
+  - ``target_include_directories``
+  - ``target_link_libraries``
+
+Let's refactor our code from `Adding a Library (Step 2)`_ to use the modern
+CMake approach of usage requirements. We first state that anybody linking to
+MathFunctions needs to include the current source directory, while
+MathFunctions itself doesn't. So  this can become an ``INTERFACE`` usage
+requirement.
+
+Remember ``INTERFACE`` means things that consumers require but the producer
+doesn't. Add the following lines to the end of ``MathFunctions/CMakeLists.txt``:
+
+.. literalinclude:: Step4/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # to find MathFunctions.h
+
+Now that we've specified usage requirements for MathFunctions we can safely
+remove our uses of the ``EXTRA_INCLUDES`` variable from the top-level
+``CMakeLists.txt``, here:
+
+.. literalinclude:: Step4/CMakeLists.txt
+  :language: cmake
+  :start-after: # add the MathFunctions library
+  :end-before: # add the executable
+
+And here:
+
+.. literalinclude:: Step4/CMakeLists.txt
+  :language: cmake
+  :start-after: # so that we will find TutorialConfig.h
+
+Once this is done, run **cmake** or **cmake-gui** to configure the project
+and then build it with your chosen build tool or by using ``cmake --build .``
+from the build directory.
+
+Installing and Testing (Step 4)
+===============================
+
+Now we can start adding install rules and testing support to our project.
+
+Install Rules
+-------------
+
+The install rules are fairly simple: for MathFunctions we want to install the
+library and header file and for the application we want to install the
+executable and configured header.
+
+So to the end of ``MathFunctions/CMakeLists.txt`` we add:
+
+.. literalinclude:: Step5/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # install rules
+
+And to the end of the top-level ``CMakeLists.txt`` we add:
+
+.. literalinclude:: Step5/CMakeLists.txt
+  :language: cmake
+  :start-after: # add the install targets
+  :end-before: # enable testing
+
+That is all that is needed to create a basic local install of the tutorial.
+
+Run **cmake** or **cmake-gui** to configure the project and then build it
+with your chosen build tool. Run the install step by typing
+``cmake --install .`` (introduced in 3.15, older versions of CMake must use
+``make install``) from the command line, or build the ``INSTALL`` target from
+an IDE. This will install the appropriate header files, libraries, and
+executables.
+
+The CMake variable ``CMAKE_INSTALL_PREFIX`` is used to determine the root of
+where the files will be installed. If using ``cmake --install`` a custom
+installation directory can be given via ``--prefix`` argument. For
+multi-configuration tools, use the ``--config`` argument to specify the
+configuration.
+
+Verify that the installed Tutorial runs.
+
+Testing Support
+---------------
+
+Next let's test our application. At the end of the top-level ``CMakeLists.txt``
+file we can enable testing and then add a number of basic tests to verify that
+the application is working correctly.
+
+.. literalinclude:: Step5/CMakeLists.txt
+  :language: cmake
+  :start-after: # enable testing
+
+The first test simply verifies that the application runs, does not segfault or
+otherwise crash, and has a zero return value. This is the basic form of a CTest
+test.
+
+The next test makes use of the ``PASS_REGULAR_EXPRESSION`` test property to
+verify that the output of the test contains certain strings. In this case,
+verifying that the usage message is printed when an incorrect number of
+arguments are provided.
+
+Lastly, we have a function called ``do_test`` that runs the application and
+verifies that the computed square root is correct for given input. For each
+invocation of ``do_test``, another test is added to the project with a name,
+input, and expected results based on the passed arguments.
+
+Rebuild the application and then cd to the binary directory and run
+``ctest -N`` and ``ctest -VV``. For multi-config generators (e.g. Visual
+Studio), the configuration type must be specified. To run tests in Debug mode,
+for example, use ``ctest -C Debug -VV`` from the build directory (not the
+Debug subdirectory!). Alternatively, build the ``RUN_TESTS`` target from the
+IDE.
+
+Adding System Introspection (Step 5)
+====================================
+
+Let us consider adding some code to our project that depends on features the
+target platform may not have. For this example, we will add some code that
+depends on whether or not the target platform has the ``log`` and ``exp``
+functions. Of course almost every platform has these functions but for this
+tutorial assume that they are not common.
+
+If the platform has ``log`` and ``exp`` then we will use them to compute the
+square root in the ``mysqrt`` function. We first test for the availability of
+these functions using the ``CheckSymbolExists`` module in the top-level
+``CMakeLists.txt``. We're going to use the new defines in
+``TutorialConfig.h.in``, so be sure to set them before that file is configured.
+
+.. literalinclude:: Step6/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # does this system provide the log and exp functions?
+  :end-before: if(HAVE_LOG AND HAVE_EXP)
+
+Now let's add these defines to ``TutorialConfig.h.in`` so that we can use them
+from ``mysqrt.cxx``:
+
+.. code-block:: console
+
+  // does the platform provide exp and log functions?
+  #cmakedefine HAVE_LOG
+  #cmakedefine HAVE_EXP
+
+Modify ``mysqrt.cxx`` to include cmath. Next, in that same file in the
+``mysqrt`` function we can provide an alternate implementation based on
+``log`` and ``exp`` if they are available on the system using the following
+code (don't forget the ``#endif`` before returning the result!):
+
+.. literalinclude:: Step6/MathFunctions/mysqrt.cxx
+  :language: c++
+  :start-after: // if we have both log and exp then use them
+  :end-before: // do ten iterations
+
+Run **cmake** or **cmake-gui** to configure the project and then build it
+with your chosen build tool and run the Tutorial executable.
+
+You will notice that we're not using ``log`` and ``exp``, even if we think they
+should be available. We should realize quickly that we have forgotten to include
+``TutorialConfig.h`` in ``mysqrt.cxx``.
+
+We will also need to update ``MathFunctions/CMakeLists.txt`` so ``mysqrt.cxx``
+knows where this file is located:
+
+.. code-block:: cmake
+
+  target_include_directories(MathFunctions
+            INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
+            PRIVATE ${CMAKE_BINARY_DIR}
+            )
+
+After making this update, go ahead and build the project again and run the built
+Tutorial executable. If ``log`` and ``exp`` are still not being used, open the
+generated ``TutorialConfig.h`` file from the build directory. Maybe they aren't
+available on the current system?
+
+Which function gives better results now, sqrt or mysqrt?
+
+Specify Compile Definition
+--------------------------
+
+Is there a better place for us to save the ``HAVE_LOG`` and ``HAVE_EXP`` values
+other than in ``TutorialConfig.h``? Let's try to use
+``target_compile_definitions``.
+
+First, remove the defines from ``TutorialConfig.h.in``. We no longer need to
+include ``TutorialConfig.h`` from ``mysqrt.cxx`` or the extra include in
+``MathFunctions/CMakeLists.txt``.
+
+Next, we can move the check for ``HAVE_LOG`` and ``HAVE_EXP`` to
+``MathFunctions/CMakeLists.txt`` and then specify those values as ``PRIVATE``
+compile definitions.
+
+.. literalinclude:: Step6/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # does this system provide the log and exp functions?
+  :end-before: # install rules
+
+After making these updates, go ahead and build the project again. Run the
+built Tutorial executable and verify that the results are same as earlier in
+this step.
+
+Adding a Custom Command and Generated File (Step 6)
+===================================================
+
+Suppose, for the purpose of this tutorial, we decide that we never want to use
+the platform ``log`` and ``exp`` functions and instead would like to
+generate a table of precomputed values to use in the ``mysqrt`` function.
+In this section, we will create the table as part of the build process,
+and then compile that table into our application.
+
+First, let's remove the check for the ``log`` and ``exp`` functions in
+``MathFunctions/CMakeLists.txt``. Then remove the check for ``HAVE_LOG`` and
+``HAVE_EXP`` from ``mysqrt.cxx``. At the same time, we can remove
+:code:`#include <cmath>`.
+
+In the ``MathFunctions`` subdirectory, a new source file named ``MakeTable.cxx``
+has been provided to generate the table.
+
+After reviewing the file, we can see that the table is produced as valid C++
+code and that the output filename is passed in as an argument.
+
+The next step is to add the appropriate commands to the
+``MathFunctions/CMakeLists.txt`` file to build the MakeTable executable and
+then run it as part of the build process. A few commands are needed to
+accomplish this.
+
+First, at the top of ``MathFunctions/CMakeLists.txt``, the executable for
+``MakeTable`` is added as any other executable would be added.
+
+.. literalinclude:: Step7/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # first we add the executable that generates the table
+  :end-before: # add the command to generate the source code
+
+Then we add a custom command that specifies how to produce ``Table.h``
+by running MakeTable.
+
+.. literalinclude:: Step7/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # add the command to generate the source code
+  :end-before: # add the main library
+
+Next we have to let CMake know that ``mysqrt.cxx`` depends on the generated
+file ``Table.h``. This is done by adding the generated ``Table.h`` to the list
+of sources for the library MathFunctions.
+
+.. literalinclude:: Step7/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # add the main library
+  :end-before: # state that anybody linking
+
+We also have to add the current binary directory to the list of include
+directories so that ``Table.h`` can be found and included by ``mysqrt.cxx``.
+
+.. literalinclude:: Step7/MathFunctions/CMakeLists.txt
+  :start-after: # state that we depend on our bin
+  :end-before: # install rules
+
+Now let's use the generated table. First, modify ``mysqrt.cxx`` to include
+``Table.h``. Next, we can rewrite the mysqrt function to use the table:
+
+.. literalinclude:: Step7/MathFunctions/mysqrt.cxx
+  :language: c++
+  :start-after: // a hack square root calculation using simple operations
+
+Run **cmake** or **cmake-gui** to configure the project and then build it
+with your chosen build tool.
+
+When this project is built it will first build the ``MakeTable`` executable.
+It will then run ``MakeTable`` to produce ``Table.h``. Finally, it will
+compile ``mysqrt.cxx`` which includes ``Table.h`` to produce the MathFunctions
+library.
+
+Run the Tutorial executable and verify that it is using the table.
+
+Building an Installer (Step 7)
+==============================
+
+Next suppose that we want to distribute our project to other people so that
+they can use it. We want to provide both binary and source distributions on a
+variety of platforms. This is a little different from the install we did
+previously in `Installing and Testing (Step 4)`_ , where we were
+installing the binaries that we had built from the source code. In this
+example we will be building installation packages that support binary
+installations and package management features. To accomplish this we will use
+CPack to create platform specific installers. Specifically we need to add
+a few lines to the bottom of our top-level ``CMakeLists.txt`` file.
+
+.. literalinclude:: Step8/CMakeLists.txt
+  :language: cmake
+  :start-after: # setup installer
+
+That is all there is to it. We start by including
+``InstallRequiredSystemLibraries``. This module will include any runtime
+libraries that are needed by the project for the current platform. Next we
+set some CPack variables to where we have stored the license and version
+information for this project. The version information was set earlier in this
+tutorial and the ``license.txt`` has been included in the top-level source
+directory for this step.
+
+Finally we include the CPack module which will use these variables and some
+other properties of the current system to setup an installer.
+
+The next step is to build the project in the usual manner and then run
+CPack on it. To build a binary distribution, from the binary directory run:
+
+.. code-block:: console
+
+  cpack
+
+To specify the generator, use the ``-G`` option. For multi-config builds, use
+``-C`` to specify the configuration. For example:
+
+.. code-block:: console
+
+  cpack -G ZIP -C Debug
+
+To create a source distribution you would type:
+
+.. code-block:: console
+
+  cpack --config CPackSourceConfig.cmake
+
+Alternatively, run ``make package`` or right click the ``Package`` target and
+``Build Project`` from an IDE.
+
+Run the installer found in the binary directory. Then run the
+installed executable and verify that it works.
+
+Adding Support for a Dashboard (Step 8)
+=======================================
+
+Adding support for submitting our test results to a dashboard is very easy. We
+already defined a number of tests for our project in `Testing Support`_. Now we
+just have to run those tests and submit them to a dashboard. To include support
+for dashboards we include the CTest module in our top-level ``CMakeLists.txt``.
+
+Replace:
+
+.. code-block:: cmake
+
+  # enable testing
+  enable_testing()
+
+With:
+
+.. code-block:: cmake
+
+  # enable dashboard scripting
+  include(CTest)
+
+The CTest module will automatically call ``enable_testing()``, so
+we can remove it from our CMake files.
+
+We will also need to create a ``CTestConfig.cmake`` file in the top-level
+directory where we can specify the name of the project and where to submit the
+dashboard.
+
+.. literalinclude:: Step9/CTestConfig.cmake
+  :language: cmake
+
+CTest will read in this file when it runs. To create a simple dashboard you can
+run **cmake** or **cmake-gui** to configure the project, but do not build it
+yet. Instead, change directory to the binary tree, and then run::
+
+  ctest [-VV] -D Experimental
+
+Remember, for multi-config generators (e.g. Visual Studio), the configuration
+type must be specified::
+
+  ctest [-VV] -C Debug -D Experimental
+
+Or, from an IDE, build the ``Experimental`` target.
+
+``ctest`` will build and test the project and submit the results to the Kitware
+public dashboard. The results of your dashboard will be uploaded to Kitware's
+public dashboard here: https://my.cdash.org/index.php?project=CMakeTutorial.
+
+Mixing Static and Shared (Step 9)
+=================================
+
+In this section we will show how by using the ``BUILD_SHARED_LIBS`` variable
+we can control the default behavior of ``add_library``, and allow control
+over how libraries without an explicit type (``STATIC``, ``SHARED``, ``MODULE``
+or ``OBJECT``) are built.
+
+To accomplish this we need to add ``BUILD_SHARED_LIBS`` to the top-level
+``CMakeLists.txt``. We use the ``option`` command as it allows users to
+optionally select if the value should be On or Off.
+
+Next we are going to refactor MathFunctions to become a real library that
+encapsulates using ``mysqrt`` or ``sqrt``, instead of requiring the calling
+code to do this logic. This will also mean that ``USE_MYMATH`` will not control
+building MathFuctions, but instead will control the behavior of this library.
+
+The first step is to update the starting section of the top-level
+``CMakeLists.txt`` to look like:
+
+.. literalinclude:: Step10/CMakeLists.txt
+  :language: cmake
+  :end-before: # add the binary tree
+
+Now that we have made MathFunctions always be used, we will need to update
+the logic of that library. So, in ``MathFunctions/CMakeLists.txt`` we need to
+create a SqrtLibrary that will conditionally be built when ``USE_MYMATH`` is
+enabled. Now, since this is a tutorial, we are going to explicitly require
+that SqrtLibrary is built statically.
+
+The end result is that ``MathFunctions/CMakeLists.txt`` should look like:
+
+.. literalinclude:: Step10/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :lines: 1-36,42-
+
+Next, update ``MathFunctions/mysqrt.cxx`` to use the ``mathfunctions`` and
+``detail`` namespaces:
+
+.. literalinclude:: Step10/MathFunctions/mysqrt.cxx
+  :language: c++
+
+We also need to make some changes in ``tutorial.cxx``, so that it no longer
+uses ``USE_MYMATH``:
+
+#. Always include ``MathFunctions.h``
+#. Always use ``mathfunctions::sqrt``
+#. Don't include cmath
+
+Finally, update ``MathFunctions/MathFunctions.h`` to use dll export defines:
+
+.. literalinclude:: Step10/MathFunctions/MathFunctions.h
+  :language: c++
+
+At this point, if you build everything, you will notice that linking fails
+as we are combining a static library without position independent code with a
+library that has position independent code. The solution to this is to
+explicitly set the ``POSITION_INDEPENDENT_CODE`` target property of SqrtLibrary
+to be True no matter the build type.
+
+.. literalinclude:: Step10/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :lines: 37-42
+
+**Exercise**: We modified ``MathFunctions.h`` to use dll export defines.
+Using CMake documentation can you find a helper module to simplify this?
+
+
+Adding Generator Expressions (Step 10)
+======================================
+
+Generator expressions are evaluated during build system generation to produce
+information specific to each build configuration.
+
+Generator expressions are allowed in the context of many target properties,
+such as ``LINK_LIBRARIES``, ``INCLUDE_DIRECTORIES``, ``COMPILE_DEFINITIONS``
+and others. They may also be used when using commands to populate those
+properties, such as ``target_link_libraries()``,
+``target_include_directories()``,
+``target_compile_definitions()`` and others.
+
+Generator expressions may be used to enable conditional linking, conditional
+definitions used when compiling, conditional include directories and more.
+The conditions may be based on the build configuration, target properties,
+platform information or any other queryable information.
+
+There are different types of generator expressions including Logical,
+Informational, and Output expressions.
+
+Logical expressions are used to create conditional output. The basic
+expressions are the 0 and 1 expressions. A ``$<0:...>`` results in the empty
+string, and ``<1:...>`` results in the content of "...".  They can also be
+nested.
+
+A common usage of generator expressions is to conditionally add compiler
+flags, such as those for language levels or warnings. A nice pattern is
+to associate this information to an ``INTERFACE`` target allowing this
+information to propagate. Lets start by constructing an ``INTERFACE``
+target and specifying the required C++ standard level of ``11`` instead
+of using ``CMAKE_CXX_STANDARD``.
+
+So the following code:
+
+.. literalinclude:: Step10/CMakeLists.txt
+  :language: cmake
+  :start-after: project(Tutorial VERSION 1.0)
+  :end-before: # control where the static and shared libraries are built so that on windows
+
+Would be replaced with:
+
+.. literalinclude:: Step11/CMakeLists.txt
+  :language: cmake
+  :start-after: project(Tutorial VERSION 1.0)
+  :end-before: # add compiler warning flags just when building this project via
+
+
+Next we add the desired compiler warning flags that we want for our
+project. As warning flags vary based on the compiler we use
+the ``COMPILE_LANG_AND_ID`` generator expression to control which
+flags to apply given a language and a set of compiler ids as seen
+below:
+
+.. literalinclude:: Step11/CMakeLists.txt
+  :language: cmake
+  :start-after: # the BUILD_INTERFACE genex
+  :end-before: # control where the static and shared libraries are built so that on windows
+
+Looking at this we see that the warning flags are encapsulated inside a
+``BUILD_INTERFACE`` condition. This is done so that consumers of our installed
+project will not inherit our warning flags.
+
+
+**Exercise**: Modify ``MathFunctions/CMakeLists.txt`` so that
+all targets have a ``target_link_libraries()`` call to ``tutorial_compiler_flags``.
+
+
+Adding Export Configuration (Step 11)
+=====================================
+
+During `Installing and Testing (Step 4)`_ of the tutorial we added the ability
+for CMake to install the library and headers of the project. During
+`Building an Installer (Step 7)`_ we added the ability to package up this
+information so it could be distributed to other people.
+
+The next step is to add the necessary information so that other CMake projects
+can use our project, be it from a build directory, a local install or when
+packaged.
+
+The first step is to update our ``install(TARGETS)`` commands to not only
+specify a ``DESTINATION`` but also an ``EXPORT``. The ``EXPORT`` keyword
+generates and installs a CMake file containing code to import all targets
+listed in the install command from the installation tree. So let's go ahead
+and explicitly ``EXPORT`` the MathFunctions library by updating the
+``install`` command in ``MathFunctions/CMakeLists.txt`` to look like:
+
+.. literalinclude:: Complete/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # install rules
+
+Now that we have MathFunctions being exported, we also need to explicitly
+install the generated ``MathFunctionsTargets.cmake`` file. This is done by
+adding the following to the bottom of the top-level ``CMakeLists.txt``:
+
+.. literalinclude:: Complete/CMakeLists.txt
+  :language: cmake
+  :start-after: # install the configuration targets
+  :end-before: include(CMakePackageConfigHelpers)
+
+At this point you should try and run CMake. If everything is setup properly
+you will see that CMake will generate an error that looks like:
+
+.. code-block:: console
+
+  Target "MathFunctions" INTERFACE_INCLUDE_DIRECTORIES property contains
+  path:
+
+    "/Users/robert/Documents/CMakeClass/Tutorial/Step11/MathFunctions"
+
+  which is prefixed in the source directory.
+
+What CMake is trying to say is that during generating the export information
+it will export a path that is intrinsically tied to the current machine and
+will not be valid on other machines. The solution to this is to update the
+MathFunctions ``target_include_directories`` to understand that it needs
+different ``INTERFACE`` locations when being used from within the build
+directory and from an install / package. This means converting the
+``target_include_directories`` call for MathFunctions to look like:
+
+.. literalinclude:: Complete/MathFunctions/CMakeLists.txt
+  :language: cmake
+  :start-after: # to find MathFunctions.h, while we don't.
+  :end-before: # should we use our own math functions
+
+Once this has been updated, we can re-run CMake and verify that it doesn't
+warn anymore.
+
+At this point, we have CMake properly packaging the target information that is
+required but we will still need to generate a ``MathFunctionsConfig.cmake`` so
+that the CMake ``find_package`` command can find our project. So let's go
+ahead and add a new file to the top-level of the project called
+``Config.cmake.in`` with the following contents:
+
+.. literalinclude:: Complete/Config.cmake.in
+
+Then, to properly configure and install that file, add the following to the
+bottom of the top-level ``CMakeLists.txt``:
+
+.. literalinclude:: Complete/CMakeLists.txt
+  :language: cmake
+  :start-after: # install the configuration targets
+  :end-before: # generate the export
+
+At this point, we have generated a relocatable CMake Configuration for our
+project that can be used after the project has been installed or packaged. If
+we want our project to also be used from a build directory we only have to add
+the following to the bottom of the top level ``CMakeLists.txt``:
+
+.. literalinclude:: Complete/CMakeLists.txt
+  :language: cmake
+  :start-after: # needs to be after the install(TARGETS ) command
+
+With this export call we now generate a ``Targets.cmake``, allowing the
+configured ``MathFunctionsConfig.cmake`` in the build directory to be used by
+other projects, without needing it to be installed.
+
+Import a CMake Project (Consumer)
+=================================
+
+This example shows how a project can find other CMake packages that
+generate ``Config.cmake`` files.
+
+It also shows how to state a project's external dependencies when generating
+a ``Config.cmake``.
+
+Packaging Debug and Release (MultiPackage)
+==========================================
+
+By default CMake's model is that a build directory only contains a single
+configuration, be it Debug, Release, MinSizeRel, or RelWithDebInfo.
+
+But it is possible to setup CPack to bundle multiple build directories at the
+same time to build a package that contains multiple configurations of the
+same project.
+
+First we need to construct a directory called ``multi_config``, which
+will contain all the builds that we want to package together.
+
+Second create a ``debug`` and ``release`` directory underneath
+``multi_config``. At the end you should have a layout that looks like:
+
+.. code-block:: none
+
+  ─ multi_config
+      ├── debug
+      └── release
+
+Now we need to setup debug and release builds, which would roughly entail
+the following:
+
+.. code-block:: console
+
+  cd debug
+  cmake -DCMAKE_BUILD_TYPE=Debug ../../MultiPackage/
+  cmake --build .
+  cd ../release
+  cmake -DCMAKE_BUILD_TYPE=Release ../../MultiPackage/
+  cmake --build .
+  cd ..
+
+
+Now that both the debug and release builds are complete, we can use
+a custom ``MultiCPackConfig.cmake`` file to package both builds into a single
+release.
+
+.. code-block:: console
+
+  cpack --config ../../MultiPackage/MultiCPackConfig.cmake

+
+Resource Allocation
+===================
+
+CTest provides a mechanism for tests to specify the resources that they need
+in a fine-grained way, and for users to specify the resources availiable on
+the running machine. This allows CTest to internally keep track of which
+resources are in use and which are free, scheduling tests in a way that
+prevents them from trying to claim resources that are not available.
+
+A common use case for this feature is for tests that require the use of a GPU.
+Multiple tests can simultaneously allocate memory from a GPU, but if too many
+tests try to do this at once, some of them will fail to allocate, resulting in
+a failed test, even though the test would have succeeded if it had the memory
+it needed. By using the resource allocation feature, each test can specify how
+much memory it requires from a GPU, allowing CTest to schedule tests in a way
+that running several of these tests at once does not exhaust the GPU's memory
+pool.
+
+Please note that CTest has no concept of what a GPU is or how much memory it
+has, nor does it have any way of communicating with a GPU to retrieve this
+information or perform any memory management. CTest simply keeps track of a
+list of abstract resource types, each of which has a certain number of slots
+available for tests to use. Each test specifies the number of slots that it
+requires from a certain resource, and CTest then schedules them in a way that
+prevents the total number of slots in use from exceeding the listed capacity.
+When a test is executed, and slots from a resource are allocated to that test,
+tests may assume that they have exclusive use of those slots for the duration
+of the test's process.
+
+The CTest resource allocation feature consists of two inputs:
+
+* The :ref:`resource specification file <ctest-resource-specification-file>`,
+  described below, which describes the resources available on the system.
+* The :prop_test:`RESOURCE_GROUPS` property of tests, which describes the
+  resources required by the test.
+
+When CTest runs a test, the resources allocated to that test are passed in the
+form of a set of
+:ref:`environment variables <ctest-resource-environment-variables>` as
+described below. Using this information to decide which resource to connect to
+is left to the test writer.
+
+The ``RESOURCE_GROUPS`` property tells CTest what resources a test expects
+to use grouped in a way meaningful to the test.  The test itself must read
+the :ref:`environment variables <ctest-resource-environment-variables>` to
+determine which resources have been allocated to each group.  For example,
+each group may correspond to a process the test will spawn when executed.
+
+Note that even if a test specifies a ``RESOURCE_GROUPS`` property, it is still
+possible for that to test to run without any resource allocation (and without
+the corresponding
+:ref:`environment variables <ctest-resource-environment-variables>`)
+if the user does not pass a resource specification file. Passing this file,
+either through the ``--resource-spec-file`` command-line argument or the
+``RESOURCE_SPEC_FILE`` argument to :command:`ctest_test`, is what activates the
+resource allocation feature. Tests should check the
+``CTEST_RESOURCE_GROUP_COUNT`` environment variable to find out whether or not
+resource allocation is activated. This variable will always (and only) be
+defined if resource allocation is activated. If resource allocation is not
+activated, then the ``CTEST_RESOURCE_GROUP_COUNT`` variable will not exist,
+even if it exists for the parent ``ctest`` process. If a test absolutely must
+have resource allocation, then it can return a failing exit code or use the
+:prop_test:`SKIP_RETURN_CODE` or :prop_test:`SKIP_REGULAR_EXPRESSION`
+properties to indicate a skipped test.
+
+.. _`ctest-resource-specification-file`:
+
+Resource Specification File
+---------------------------
+
+The resource specification file is a JSON file which is passed to CTest, either
+on the :manual:`ctest(1)` command line as ``--resource-spec-file``, or as the
+``RESOURCE_SPEC_FILE`` argument of :command:`ctest_test`. The resource
+specification file must be a JSON object. All examples in this document assume
+the following resource specification file:
+
+.. code-block:: json
+
+  {
+    "version": {
+      "major": 1,
+      "minor": 0
+    },
+    "local": [
+      {
+        "gpus": [
+          {
+            "id": "0",
+            "slots": 2
+          },
+          {
+            "id": "1",
+            "slots": 4
+          },
+          {
+            "id": "2",
+            "slots": 2
+          },
+          {
+            "id": "3"
+          }
+        ],
+        "crypto_chips": [
+          {
+            "id": "card0",
+            "slots": 4
+          }
+        ]
+      }
+    ]
+  }
+
+The members are:
+
+``version``
+  An object containing a ``major`` integer field and a ``minor`` integer field.
+  Currently, the only supported version is major ``1``, minor ``0``. Any other
+  value is an error.
+
+``local``
+  A JSON array of resource sets present on the system.  Currently, this array
+  is restricted to being of size 1.
+
+  Each array element is a JSON object with members whose names are equal to the
+  desired resource types, such as ``gpus``. These names must start with a
+  lowercase letter or an underscore, and subsequent characters can be a
+  lowercase letter, a digit, or an underscore. Uppercase letters are not
+  allowed, because certain platforms have case-insensitive environment
+  variables. See the `Environment Variables`_ section below for
+  more information. It is recommended that the resource type name be the plural
+  of a noun, such as ``gpus`` or ``crypto_chips`` (and not ``gpu`` or
+  ``crypto_chip``.)
+
+  Please note that the names ``gpus`` and ``crypto_chips`` are just examples,
+  and CTest does not interpret them in any way. You are free to make up any
+  resource type you want to meet your own requirements.
+
+  The value for each resource type is a JSON array consisting of JSON objects,
+  each of which describe a specific instance of the specified resource. These
+  objects have the following members:
+
+  ``id``
+    A string consisting of an identifier for the resource. Each character in
+    the identifier can be a lowercase letter, a digit, or an underscore.
+    Uppercase letters are not allowed.
+
+    Identifiers must be unique within a resource type. However, they do not
+    have to be unique across resource types. For example, it is valid to have a
+    ``gpus`` resource named ``0`` and a ``crypto_chips`` resource named ``0``,
+    but not two ``gpus`` resources both named ``0``.
+
+    Please note that the IDs ``0``, ``1``, ``2``, ``3``, and ``card0`` are just
+    examples, and CTest does not interpret them in any way. You are free to
+    make up any IDs you want to meet your own requirements.
+
+  ``slots``
+    An optional unsigned number specifying the number of slots available on the
+    resource. For example, this could be megabytes of RAM on a GPU, or
+    cryptography units available on a cryptography chip. If ``slots`` is not
+    specified, a default value of ``1`` is assumed.
+
+In the example file above, there are four GPUs with ID's 0 through 3. GPU 0 has
+2 slots, GPU 1 has 4, GPU 2 has 2, and GPU 3 has a default of 1 slot. There is
+also one cryptography chip with 4 slots.
+
+``RESOURCE_GROUPS`` Property
+----------------------------
+
+See :prop_test:`RESOURCE_GROUPS` for a description of this property.
+
+.. _`ctest-resource-environment-variables`:
+
+Environment Variables
+---------------------
+
+Once CTest has decided which resources to allocate to a test, it passes this
+information to the test executable as a series of environment variables. For
+each example below, we will assume that the test in question has a
+:prop_test:`RESOURCE_GROUPS` property of
+``2,gpus:2;gpus:4,gpus:1,crypto_chips:2``.
+
+The following variables are passed to the test process:
+
+.. envvar:: CTEST_RESOURCE_GROUP_COUNT
+
+  The total number of groups specified by the :prop_test:`RESOURCE_GROUPS`
+  property. For example:
+
+  * ``CTEST_RESOURCE_GROUP_COUNT=3``
+
+  This variable will only be defined if :manual:`ctest(1)` has been given a
+  ``--resource-spec-file``, or if :command:`ctest_test` has been given a
+  ``RESOURCE_SPEC_FILE``. If no resource specification file has been given,
+  this variable will not be defined.
+
+.. envvar:: CTEST_RESOURCE_GROUP_<num>
+
+  The list of resource types allocated to each group, with each item
+  separated by a comma. ``<num>`` is a number from zero to
+  ``CTEST_RESOURCE_GROUP_COUNT`` minus one. ``CTEST_RESOURCE_GROUP_<num>``
+  is defined for each ``<num>`` in this range. For example:
+
+  * ``CTEST_RESOURCE_GROUP_0=gpus``
+  * ``CTEST_RESOURCE_GROUP_1=gpus``
+  * ``CTEST_RESOURCE_GROUP_2=crypto_chips,gpus``
+
+.. envvar:: CTEST_RESOURCE_GROUP_<num>_<resource-type>
+
+  The list of resource IDs and number of slots from each ID allocated to each
+  group for a given resource type. This variable consists of a series of
+  pairs, each pair separated by a semicolon, and with the two items in the pair
+  separated by a comma. The first item in each pair is ``id:`` followed by the
+  ID of a resource of type ``<resource-type>``, and the second item is
+  ``slots:`` followed by the number of slots from that resource allocated to
+  the given group. For example:
+
+  * ``CTEST_RESOURCE_GROUP_0_GPUS=id:0,slots:2``
+  * ``CTEST_RESOURCE_GROUP_1_GPUS=id:2,slots:2``
+  * ``CTEST_RESOURCE_GROUP_2_GPUS=id:1,slots:4;id:3,slots:1``
+  * ``CTEST_RESOURCE_GROUP_2_CRYPTO_CHIPS=id:card0,slots:2``
+
+  In this example, group 0 gets 2 slots from GPU ``0``, group 1 gets 2 slots
+  from GPU ``2``, and group 2 gets 4 slots from GPU ``1``, 1 slot from GPU
+  ``3``, and 2 slots from cryptography chip ``card0``.
+
+  ``<num>`` is a number from zero to ``CTEST_RESOURCE_GROUP_COUNT`` minus one.
+  ``<resource-type>`` is the name of a resource type, converted to uppercase.
+  ``CTEST_RESOURCE_GROUP_<num>_<resource-type>`` is defined for the product
+  of each ``<num>`` in the range listed above and each resource type listed in
+  ``CTEST_RESOURCE_GROUP_<num>``.
+
+  Because some platforms have case-insensitive names for environment variables,
+  the names of resource types may not clash in a case-insensitive environment.
+  Because of this, for the sake of simplicity, all resource types must be
+  listed in all lowercase in the
+  :ref:`resource specification file <ctest-resource-specification-file>` and
+  in the :prop_test:`RESOURCE_GROUPS` property, and they are converted to all
+  uppercase in the ``CTEST_RESOURCE_GROUP_<num>_<resource-type>`` environment
+  variable.

+RESOURCE_GROUPS
+---------------
+
+Specify resources required by a test, grouped in a way that is meaningful to
+the test.  See :ref:`resource allocation <ctest-resource-allocation>`
+for more information on how this property integrates into the CTest resource
+allocation feature.
+
+The ``RESOURCE_GROUPS`` property is a :ref:`semicolon-separated list <CMake
+Language Lists>` of group descriptions. Each entry consists of an optional
+number of groups using the description followed by a series of resource
+requirements for those groups. These requirements (and the number of groups)
+are separated by commas. The resource requirements consist of the name of a
+resource type, followed by a colon, followed by an unsigned integer
+specifying the number of slots required on one resource of the given type.
+
+The ``RESOURCE_GROUPS`` property tells CTest what resources a test expects
+to use grouped in a way meaningful to the test.  The test itself must read
+the :ref:`environment variables <ctest-resource-environment-variables>` to
+determine which resources have been allocated to each group.  For example,
+each group may correspond to a process the test will spawn when executed.
+
+Consider the following example:
+
+.. code-block:: cmake

+  set_property(TEST MyTest PROPERTY RESOURCE_GROUPS
+    "2,gpus:2"
+    "gpus:4,crypto_chips:2")
+
+In this example, there are two group descriptions (implicitly separated by a
+semicolon.) The content of the first description is ``2,gpus:2``. This
+description specifies 2 groups, each of which requires 2 slots from a single
+GPU. The content of the second description is ``gpus:4,crypto_chips:2``. This
+description does not specify a group count, so a default of 1 is assumed.
+This single group requires 4 slots from a single GPU and 2 slots from a
+single cryptography chip. In total, 3 resource groups are specified for this
+test, each with its own unique requirements.
+
+Note that the number of slots following the resource type specifies slots from
+a *single* instance of the resource. If the resource group can tolerate
+receiving slots from different instances of the same resource, it can indicate
+this by splitting the specification into multiple requirements of one slot. For
+example:
+
+.. code-block:: cmake
+
+  add_test(NAME MyTest COMMAND MyExe)
+  set_property(TEST MyTest PROPERTY RESOURCE_GROUPS
+    "gpus:1,gpus:1,gpus:1,gpus:1")
+
+In this case, the single resource group indicates that it needs four GPU slots,
+all of which may come from separate GPUs (though they don't have to; CTest may
+still assign slots from the same GPU.)
+
+When CTest sets the :ref:`environment variables
+<ctest-resource-environment-variables>` for a test, it assigns a group number
+based on the group description, starting at 0 on the left and the number of
+groups minus 1 on the right. For example, in the example above, the two
+groups in the first description would have IDs of 0 and 1, and the single
+group in the second description would have an ID of 2.
+
+Both the ``RESOURCE_GROUPS`` and :prop_test:`RESOURCE_LOCK` properties serve
+similar purposes, but they are distinct and orthogonal. Resources specified by
+``RESOURCE_GROUPS`` do not affect :prop_test:`RESOURCE_LOCK`, and vice versa.
+Whereas :prop_test:`RESOURCE_LOCK` is a simpler property that is used for
+locking one global resource, ``RESOURCE_GROUPS`` is a more advanced property
+that allows multiple tests to simultaneously use multiple resources of the
+same type, specifying their requirements in a fine-grained manner.

+-------------------
+
+When this property is ``ON``, CMake will generate the ``-p`` path prefix

+
+To generate the path prefix, CMake tests if the header compiled by ``moc``

+compute the relative path accordingly.  If the header is not in the

+This property is initialized by the value of the :variable:`CMAKE_UNITY_BUILD`
+variable when a target is created.
+
+.. note::
+
+  Projects should not directly set the ``UNITY_BUILD`` property or its
+  associated :variable:`CMAKE_UNITY_BUILD` variable to true.  Depending
+  on the capabilities of the build machine and compiler used, it might or
+  might not be appropriate to enable unity builds.  Therefore, this feature
+  should be under developer control, which would normally be through the
+  developer choosing whether or not to set the :variable:`CMAKE_UNITY_BUILD`
+  variable on the :manual:`cmake(1)` command line or some other equivalent
+  method.  However, it IS recommended to set the ``UNITY_BUILD`` target
+  property to false if it is known that enabling unity builds for the
+  target can lead to problems.
+
+ODR (One definition rule) errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When multiple source files are included into one source file, as is done
+for unity builds, it can potentially lead to ODR errors.  CMake provides
+a number of measures to help address such problems:
+
+* Any source file that has a non-empty :prop_sf:`COMPILE_OPTIONS`,
+  :prop_sf:`COMPILE_DEFINITIONS`, :prop_sf:`COMPILE_FLAGS`, or
+  :prop_sf:`INCLUDE_DIRECTORIES` source property will not be combined
+  into a unity source.
+
+* Projects can prevent an individual source file from being combined into
+  a unity source by setting its :prop_sf:`SKIP_UNITY_BUILD_INCLUSION`
+  source property to true.  This can be a more effective way to prevent
+  problems with specific files than disabling unity builds for an entire
+  target.
+
+* The :prop_tgt:`UNITY_BUILD_CODE_BEFORE_INCLUDE` and
+  :prop_tgt:`UNITY_BUILD_CODE_AFTER_INCLUDE` target properties can be used
+  to inject code into the unity source files before and after every
+  ``#include`` statement.
+
+* The order of source files added to the target via commands like
+  :command:`add_library`, :command:`add_executable` or
+  :command:`target_sources` will be preserved in the generated unity source
+  files.  This can be used to manually enforce a specific grouping based on
+  the :prop_tgt:`UNITY_BUILD_BATCH_SIZE` target property.

+UNITY_BUILD_BATCH_SIZE
+----------------------
+
+Specifies the maximum number of source files that can be combined into any one
+unity source file when unity builds are enabled by the :prop_tgt:`UNITY_BUILD`
+target property.  The original source files will be distributed across as many
+unity source files as necessary to honor this limit.
+
+The initial value for this property is taken from the
+:variable:`CMAKE_UNITY_BUILD_BATCH_SIZE` variable when the target is created.
+If that variable has not been set, the initial value will be 8.
+
+The batch size needs to be selected carefully.  If set too high, the size of
+the combined source files could result in the compiler using excessive memory
+or hitting other similar limits.  In extreme cases, this can even result in
+build failure.  On the other hand, if the batch size is too low, there will be
+little gain in build performance.
+
+Although strongly discouraged, the batch size may be set to a value of 0 to
+combine all the sources for the target into a single unity file, regardless of
+how many sources are involved.  This runs the risk of creating an excessively
+large unity source file and negatively impacting the build performance, so
+a value of 0 is not generally recommended.

+CMake 3.16 Release Notes
+************************
+
+.. only:: html
+
+  .. contents::
+
+Changes made since CMake 3.15 include the following.
+
+New Features
+============
+
+Languages
+---------
+
+* CMake learned to support the Objective C (``OBJC``) and Objective C++
+  (``OBJCXX``) languages.  They may be enabled via the :command:`project`
+  and :command:`enable_language` commands.  When ``OBJC`` or ``OBJCXX``
+  is enabled, source files with the ``.m`` or ``.mm``, respectively,
+  will be compiled as Objective C or C++.  Otherwise they will be treated
+  as plain C++ sources as they were before.
+
+Compilers
+---------
+
+* The ``Clang`` compiler is now supported on ``Solaris``.
+
+Platforms
+---------
+
+* On AIX, executables using the :prop_tgt:`ENABLE_EXPORTS` target property
+  now produce a linker import file with a ``.imp`` extension in addition
+  to the executable file.  Plugins (created via :command:`add_library` with
+  the ``MODULE`` option) that use :command:`target_link_libraries` to link
+  to the executable for its symbols are now linked using the import file.
+  The :command:`install(TARGETS)` command now installs the import file as
+  an ``ARCHIVE`` artifact.
+
+* On AIX, runtime linking is no longer enabled by default.  CMake provides
+  the linker enough information to resolve all symbols up front.
+  One may manually enable runtime linking for shared libraries and/or
+  loadable modules by adding ``-Wl,-G`` to their link flags
+  (e.g. in the :variable:`CMAKE_SHARED_LINKER_FLAGS` or
+  :variable:`CMAKE_MODULE_LINKER_FLAGS` variable).
+  One may manually enable runtime linking for executables by adding
+  ``-Wl,-brtl`` to their link flags (e.g. in the
+  :variable:`CMAKE_EXE_LINKER_FLAGS` variable).
+
+Command-Line
+------------
+
+* :manual:`cmake(1)` ``-E`` now supports ``true`` and ``false`` commands,
+  which do nothing while returning exit codes of 0 and 1, respectively.
+
+* :manual:`cmake(1)` gained a ``--trace-redirect=<file>`` command line
+  option that can be used to redirect ``--trace`` output to a file instead
+  of ``stderr``.
+
+* The :manual:`cmake(1)` ``--loglevel`` command line option has been
+  renamed to ``--log-level`` to make it consistent with the naming of other
+  command line options.  The ``--loglevel`` option is still supported to
+  preserve backward compatibility.
+
+Commands
+--------
+
+* The :command:`add_test` command learned the option ``COMMAND_EXPAND_LISTS``
+  which causes lists in the ``COMMAND`` argument to be expanded, including
+  lists created by generator expressions.
+
+* The :command:`file` command learned a new sub-command,
+  ``GET_RUNTIME_DEPENDENCIES``, which allows you to recursively get the list of
+  libraries linked by an executable or library. This sub-command is intended as
+  a replacement for :module:`GetPrerequisites`.
+
+* The :command:`find_file`, :command:`find_library`, :command:`find_path`,
+  :command:`find_package`, and :command:`find_program` commands have learned to
+  check the following variables to control the default behavior for groups of
+  search locations:
+
+  * :variable:`CMAKE_FIND_USE_PACKAGE_ROOT_PATH` - Controls the default
+    behavior of searching the :variable:`<PackageName>_ROOT` variables.
+
+  * :variable:`CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH` - Controls the default
+    behavior of searching the CMake-specific environment variables.
+
+  * :variable:`CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH` - Controls the default
+    behavior of searching the standard system environment variables.
+
+  * :variable:`CMAKE_FIND_USE_CMAKE_PATH` - Controls the default behavior of
+    searching the CMake-specific cache variables.
+
+  * :variable:`CMAKE_FIND_USE_CMAKE_SYSTEM_PATH` - Controls the default
+    behavior of searching the platform-specific CMake variables.
+
+* The :command:`find_package` command has learned to check the
+  :variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY` variable to control the default
+  behavior of searching the CMake user package registry and to check the
+  :variable:`CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY` variable to control
+  the default behavior of searching the CMake system package registry.
+
+* The :command:`message` command learned indentation control with the new
+  :variable:`CMAKE_MESSAGE_INDENT` variable.
+
+* The :command:`target_precompile_headers` command was added to specify
+  a list of headers to precompile for faster compilation times.
+
+Variables
+---------
+
+* The :variable:`CMAKE_CUDA_RESOLVE_DEVICE_SYMBOLS` variable has been
+  introduced to optionally initialize the
+  :prop_tgt:`CUDA_RESOLVE_DEVICE_SYMBOLS` target property.
+
+* The :variable:`CMAKE_ECLIPSE_RESOURCE_ENCODING` variable was added to
+  specify the resource encoding for the the :generator:`Eclipse CDT4` extra
+  generator.
+
+* The :variable:`CMAKE_UNITY_BUILD` variable was added to initialize the
+  :prop_tgt:`UNITY_BUILD` target property to tell generators to batch
+  include source files for faster compilation times.
+
+Properties
+----------
+
+* The :prop_tgt:`BUILD_RPATH` and :prop_tgt:`INSTALL_RPATH` target properties
+  now support :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+* The :prop_tgt:`INSTALL_REMOVE_ENVIRONMENT_RPATH` target property was
+  added to remove compiler-defined ``RPATH`` entries from a target.
+  This property is initialized by the
+  :variable:`CMAKE_INSTALL_REMOVE_ENVIRONMENT_RPATH` variable.
+
+* The :prop_tgt:`PRECOMPILE_HEADERS` target property was added to specify
+  a list of headers to precompile for faster compilation times.
+  Set it using the :command:`target_precompile_headers` command.
+
+* The :prop_tgt:`UNITY_BUILD` target property was added to tell
+  generators to batch include source files for faster compilation
+  times.
+
+* The :prop_tgt:`VS_CONFIGURATION_TYPE` target property now supports
+  :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+* The :prop_tgt:`VS_DPI_AWARE` target property was added to tell
+  :ref:`Visual Studio Generators` to set the ``EnableDpiAwareness``
+  property in ``.vcxproj`` files.
+
+* The :prop_tgt:`XCODE_SCHEME_DEBUG_DOCUMENT_VERSIONING` target property was
+  added to tell the :generator:`Xcode` generator to set the value of the
+  ``Allow debugging when using document Versions Browser`` schema option.
+
+Modules
+-------
+
+* The :module:`FindDoxygen` module :command:`doxygen_add_docs` command
+  gained a new ``USE_STAMP_FILE`` option.  When this option present,
+  the custom target created by the command will only re-run Doxygen if
+  any of the source files have changed since the last successful run.
+
+* The :module:`FindGnuTLS` module now provides an imported target.
+
+* The :module:`FindPackageHandleStandardArgs` module
+  :command:`find_package_handle_standard_args` command gained
+  a new ``REASON_FAILURE_MESSAGE`` option to specify a message
+  giving the reason for the failure.
+
+* The :module:`FindPkgConfig` module :command:`pkg_search_module` macro
+  now defines a ``<prefix>_MODULE_NAME`` result variable containing the
+  first matching module name.
+
+* The :module:`FindPython3` and :module:`FindPython` modules gained
+  options to control which ``ABIs`` will be searched.
+
+* The :module:`FindPython3`, :module:`FindPython2`, and :module:`FindPython`
+  modules now support direct specification of artifacts via cache entries.
+
+Autogen
+-------
+
+* When using :prop_tgt:`AUTOMOC`, CMake now generates the ``-p`` path prefix
+  option for ``moc``.  This ensures that ``moc`` output files are identical
+  on different build setups (given, that the headers compiled by ``moc`` are
+  in an :command:`include directory <target_include_directories>`).
+  Also it ensures that ``moc`` output files will compile correctly when the
+  source and/or build directory is a symbolic link.
+
+  The ``moc`` path prefix generation behavior can be configured by setting
+  the new :variable:`CMAKE_AUTOMOC_PATH_PREFIX` variable and/or
+  :prop_tgt:`AUTOMOC_PATH_PREFIX` target property.
+
+CTest
+-----
+
+* :manual:`ctest(1)` now has the ability to schedule tests based on resource
+  requirements for each test. See :ref:`ctest-resource-allocation` for
+  details.
+
+* A new test property, :prop_test:`SKIP_REGULAR_EXPRESSION`, has been added.
+  This property is similar to :prop_test:`FAIL_REGULAR_EXPRESSION` and
+  :prop_test:`PASS_REGULAR_EXPRESSION`, but with the same meaning as
+  :prop_test:`SKIP_RETURN_CODE`. This is useful, for example, in cases where
+  the user has no control over the return code of the test. For example, in
+  Catch2, the return value is the number of assertion failed, therefore it is
+  impossible to use it for :prop_test:`SKIP_RETURN_CODE`.
+
+CPack
+-----
+
+* :manual:`cpack(1)` learned support for multiple configurations for ``-C``
+  option.
+
+* The :cpack_gen:`CPack DEB Generator` is now able to format generic text
+  (usually used as the description for multiple CPack generators) according
+  to the `Debian Policy Manual`_.  See the
+  :variable:`CPACK_PACKAGE_DESCRIPTION_FILE` and
+  :variable:`CPACK_DEBIAN_<COMPONENT>_DESCRIPTION` variables.
+
+* The :cpack_gen:`CPack Archive Generator` learned to generate ``.tar.zst``
+  packages with Zstandard compression.
+
+.. _`Debian Policy Manual`: https://www.debian.org/doc/debian-policy/ch-controlfields.html#description
+
+Deprecated and Removed Features
+===============================
+
+* An explicit deprecation diagnostic was added for policy ``CMP0067``
+  (``CMP0066`` and below were already deprecated).
+  The :manual:`cmake-policies(7)` manual explains that the OLD behaviors
+  of all policies are deprecated and that projects should port to the
+  NEW behaviors.
+
+* The :variable:`CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY` variable has been
+  deprecated.  Use the :variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY` variable
+  instead.
+
+* The :module:`GetPrerequisites` module has been deprecated, as it has been
+  superceded by :command:`file(GET_RUNTIME_DEPENDENCIES)`.
+
+* The ``CPACK_INSTALL_SCRIPT`` variable has been deprecated in favor of the
+  new, more accurately named :variable:`CPACK_INSTALL_SCRIPTS` variable.
+
+Other Changes
+=============
+
+* The :manual:`cmake(1)` ``-C <initial-cache>`` option now evaluates the
+  initial cache script with :variable:`CMAKE_SOURCE_DIR` and
+  :variable:`CMAKE_BINARY_DIR` set to the top-level source and build trees.
+
+* The :manual:`cmake(1)` ``-E remove_directory`` command-line tool,
+  when given the path to a symlink to a directory, now removes just
+  the symlink.  It no longer removes content of the linked directory.
+
+* The :manual:`ctest(1)`  ``--build-makeprogram`` command-line option now
+  specifies the make program used when configuring a project with the
+  :generator:`Ninja` generator or the :ref:`Makefile Generators`.
+
+* The :module:`ExternalProject` module :command:`ExternalProject_Add` command
+  has been updated so that ``GIT_SUBMODULES ""`` initializes no submodules.
+  See policy :policy:`CMP0097`.
+
+* The :module:`FindGTest` module has been updated to recognize
+  MSVC build trees generated by GTest 1.8.1.
+
+* The :command:`project` command no longer strips leading zeros in version
+  components.  See policy :policy:`CMP0096`.
+
+* The Qt Compressed Help file is now named ``CMake.qch``, which no longer
+  contains the release version in the file name.  When CMake is upgraded
+  in-place, the name and location of this file will remain constant.
+  Tools such as IDEs, help viewers, etc. should now be able to refer to this
+  file at a fixed location that remains valid across CMake upgrades.
+
+* ``RPATH`` entries are properly escaped in the generated CMake scripts
+  used for installation.  See policy :policy:`CMP0095`.
+
+* When using :variable:`CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS` on Windows the
+  auto-generated exports are now updated only when the object files
+  providing the symbols are updated.

+
+  Check that the source supplied in ``<code>`` can be compiled as a Objectie-C source
+  file and linked as an executable (so it must contain at least a ``main()``
+  function). The result will be stored in the internal cache variable specified
+  by ``<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.
+
+  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_objc_source_compiles()``:
+
+  ``CMAKE_REQUIRED_FLAGS``
+    Additional flags to pass to the compiler. Note that the contents of
+    :variable:`CMAKE_OBJC_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_QUIET``
+    If this variable evaluates to a boolean true value, all status messages

+CheckOBJCXXSourceRuns
+---------------------
+
+Check if given Objective-C++ source compiles and links into an executable and can
+subsequently be run.
+
+.. command:: check_objcxx_source_runs
+
+  .. code-block:: cmake
+
+    check_objcxx_source_runs(<code> <resultVar>)
+
+  Check that the source supplied in ``<code>`` can be compiled as a Objective-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_objcxx_source_runs()``:
+
+  ``CMAKE_REQUIRED_FLAGS``
+    Additional flags to pass to the compiler. Note that the contents of
+    :variable:`CMAKE_OBJCXX_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.
+
+  ``CMAKE_REQUIRED_LINK_OPTIONS``
+    A :ref:`;-list <CMake Language Lists>` of options to add to the link
+    command (see :command:`try_run` 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_run` 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.

+``Python_COMPILER``

+
+``Python_LIBRARY``
+  The path to the library. It will be used to compute the

+
+``Python_INCLUDE_DIR``
+  The path to the directory of the ``Python`` headers. It will be used to
+  compute the variable ``Python_INCLUDE_DIRS``.
+
+``Python_NumPy_INCLUDE_DIR``
+  The path to the directory of the ``NumPy`` headers. It will be used to
+  compute the variable ``Python_NumPy_INCLUDE_DIRS``.
+
+.. note::
+
+  All paths must be absolute. Any artifact specified with a relative path
+  will be ignored.
+
+.. note::
+
+  When an artifact is specified, all ``HINTS`` will be ignored and no search

+
+``Python2_COMPILER``
+  The path to the compiler.
+

+  The path to the directory of the ``NumPy`` headers. It will be used to

+
+.. note::
+
+  All paths must be absolute. Any artifact specified with a relative path
+  will be ignored.
+
+.. note::
+
+  When an artifact is specified, all ``HINTS`` will be ignored and no search

+  Each element can be set to one of the following:
+
+  * ``ON``: Corresponding flag is selected.
+  * ``OFF``: Corresponding flag is not selected.
+  * ``ANY``: The two posibilties (``ON`` and ``OFF``) will be searched.
+
+  From this 3-tuple, various ABIs will be searched starting from the most

+    result.
+
+Artifacts Specification
+^^^^^^^^^^^^^^^^^^^^^^^
+
+To solve special cases, it is possible to specify directly the artifacts by
+setting the following variables:
+
+``Python3_EXECUTABLE``
+  The path to the interpreter.
+
+``Python3_COMPILER``
+  The path to the compiler.
+
+``Python3_LIBRARY``
+  The path to the library. It will be used to compute the
+  variables ``Python3_LIBRARIES``, ``Python3_LIBRAY_DIRS`` and
+  ``Python3_RUNTIME_LIBRARY_DIRS``.
+
+``Python3_INCLUDE_DIR``
+  The path to the directory of the ``Python`` headers. It will be used to
+  compute the variable ``Python3_INCLUDE_DIRS``.
+
+``Python3_NumPy_INCLUDE_DIR``
+  The path to the directory of the ``NumPy`` headers. It will be used to
+  compute the variable ``Python3_NumPy_INCLUDE_DIRS``.
+
+.. note::
+
+  All paths must be absolute. Any artifact specified with a relative path
+  will be ignored.
+
+.. note::
+
+  When an artifact is specified, all ``HINTS`` will be ignored and no search
+  will be performed for this artifact.
+
+  If more than one artifact is specified, it is the user's responsability to
+  ensure the consistency of the various artifacts.
+

+ * This helper program is used to verify that the CTest resource allocation
+ * feature is working correctly. It consists of two stages:
+ *
+ * 1) write - This stage receives the RESOURCE_GROUPS property of the test and
+ *    compares it with the values passed in the CTEST_RESOURCE_GROUP_*
+ *    environment variables. If it received all of the resources it expected,
+ *    then it writes this information to a log file, which will be read in
+ *    the verify stage.
+ * 2) verify - This stage compares the log file with the resource spec file to
+ *    make sure that no resources were over-subscribed, deallocated without
+ *    being allocated, or allocated without being deallocated.

+This directory contains sample input files for the implicit include
+directories, and link info parsers for testing.  For each configuration
+ there is one ".input" file and matching ".output" files in
+ParseImplicitIncludeInfo/results and ParseImplicitLinkInfo/results.
+
+To generate ".input" files for a system, create a temporary build
+directory and chdir to it.  Then run cmake pointing to this directory.
+The CMakeLists.txt file here will generate ".input" files in your
+build directory.  The default set of languages is C and CXX.  This
+can be changed with -DLANGUAGES=language_list.  For example:
+-DLANGUAGES=Fortran will generate Fortran parser input.
+
+The ".output" files should be generated by hand from the input files.
+The test will compare the parser output to the manually generated
+".output" file.  The two should match.
+
+For compilers that support "-nostdinc"-like flags, you can generate
+a test for this with a command like:
+cmake -DUNAME=netbsd_nostdinc \
+  -DCMAKE_C_FLAGS=-nostdinc -DCMAKE_CXX_FLAGS=-nostdinc .
+
+Here is an example for testing the XL compiler with both -I and nostdinc:
+
+env CC=xlc CXX=xlC cmake -DUNAME=linux_nostdinc_i \
+  -DCMAKE_C_FLAGS='-qnostdinc -I/tmp/ii/test_c' \
+  -DCMAKE_CXX_FLAGS='-qnostdinc -I/tmp/ii/test_c -I/tmp/ii/test_cxx' .

-This directory contains sample input files for the implicit include
-directories parser for testing.  For each configuration there is one
-".input" file and one ".output" file.
-
-To generate ".input" files for a system, create a temporary build
-directory and chdir to it.  Then run cmake pointing to this directory.
-The CMakeLists.txt file here will generate ".input" files in your
-build directory.  The default set of languages is C and CXX.  This
-can be changed with -DLANGUAGES=language_list.  For example:
--DLANGUAGES=Fortran will generate Fortran parser input.
-
-The ".output" files should be generated by hand from the input files.
-The test will compare the parser output to the manually generated
-".output" file.  The two should match.
-
-For compilers that support "-nostdinc"-like flags, you can generate
-a test for this with a command like:
-cmake -DUNAME=netbsd_nostdinc \
-  -DCMAKE_C_FLAGS=-nostdinc -DCMAKE_CXX_FLAGS=-nostdinc .
-
-Here is an example for testing the XL compiler with both -I and nostdinc:
-
-env CC=xlc CXX=xlC cmake -DUNAME=linux_nostdinc_i \
-  -DCMAKE_C_FLAGS='-qnostdinc -I/tmp/ii/test_c' \
-  -DCMAKE_CXX_FLAGS='-qnostdinc -I/tmp/ii/test_c -I/tmp/ii/test_cxx' .

-# Packaging Debug and Release #
-
-By default CMake is model is that a build directory only contains a single
-configuration, be it Debug, Release, MinSizeRel, or RelWithDebInfo.
-
-But it is possible to setup CPack to bundle multiple build directories at the same
-time to build a package that contains multiple configurations of the same project.
-
-First we need to ahead and construct a directory called 'multi_config' this
-will contain all the builds that we want to package together.
-
-Second create a 'debug' and 'release' directory underneath 'multi_config'. At
-the end you should have a layout that looks like:
-
-─ multi_config
-    ├── debug
-    └── release
-
-Now we need to setup debug and release builds, which would roughly entail
-the following:
-
-  cd debug
-  cmake -DCMAKE_BUILD_TYPE=Debug ../../MultiPackage/
-  cmake --build .
-  cd ../release
-  cmake -DCMAKE_BUILD_TYPE=Release ../../MultiPackage/
-  cmake --build .
-  cd ..
-
-
-Now that both the debug and release builds are complete we can now use
-the custom MultiCPackConfig to package both builds into a single release.
-
-  cpack --config ../../MultiPackage/MultiCPackConfig.cmake

-# Adding a Version Number and Configured Header File #
-
-The first feature we will add is to provide our executable and project with a
-version number. While we could do this exclusively in the source code, using
-CMakeLists provides more flexibility.
-
-To add a version number we modify the CMakeLists file as follows:
-
-  cmake_minimum_required(VERSION 3.3)
-  project(Tutorial)
-
-  # the version number.
-  set(Tutorial_VERSION_MAJOR 1)
-  set(Tutorial_VERSION_MINOR 0)
-
-  # configure a header file to pass some of the CMake settings
-  # to the source code
-  configure_file(
-    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
-    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
-    )
-
-  # add the executable
-  add_executable(Tutorial tutorial.cxx)
-
-  # add the binary tree to the search path for include files
-  # so that we will find TutorialConfig.h
-  target_include_directories(Tutorial PUBLIC
-                             "${PROJECT_BINARY_DIR}"
-                             )
-
-
-We then create a TutorialConfig.h.in file in the source tree with the
-following contents:
-
-  // the configured options and settings for Tutorial
-  #define Tutorial_VERSION_MAJOR @Tutorial_VERSION_MAJOR@
-  #define Tutorial_VERSION_MINOR @Tutorial_VERSION_MINOR@
-
-When CMake configures this header file the values for @Tutorial_VERSION_MAJOR@
-and @Tutorial_VERSION_MINOR@ will be replaced by the values from the CMakeLists
-file. Next we modify tutorial.cxx to include the configured header file and to
-make use of the version numbers. The resulting source code is listed below.
-
-  // A simple program that computes the square root of a number
-  #include <cmath>
-  #include <iostream>
-  #include <string>
-  #include <sstream>
-
-  #include "TutorialConfig.h"
-
-  int main (int argc, char *argv[])
-  {
-    if (argc < 2) {
-      std::cout << argv[0] << " Version "
-                << Tutorial_VERSION_MAJOR << "." << Tutorial_VERSION_MINOR
-                << std::endl;
-      std::cout << "Usage: " << argv[0] << " number" << std::endl;
-      return 1;
-    }
-
-    double inputValue = atof(argv[1]);
-
-    double outputValue = sqrt(inputValue);
-    std::cout << "The square root of "
-              << inputValue << " is " << outputValue << std::endl;
-    return 0;
-  }
-
-# Adding C++11 support #
-
-Let's add some C++11 features to our project. We will need to explicitly state
-in the CMake code that it should use the correct flags. The easiest way to
-enable C++11 support for CMake is by using the CMAKE_CXX_STANDARD
-and CMAKE_CXX_STANDARD_REQUIRED variables.
-
-First, replace `atof` with `std::stod` in tutorial.cxx.
-
-Then, add the CMAKE_CXX_STANDARD and CMAKE_CXX_STANDARD_REQUIRED variables to
-the CMakeLists file. The STANADARD value should be set to 11, and REQUIRED
-should be set to True.
-
-
-# Build and Test #
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool
-
-cd to the directory where Tutorial was built (likely the make directory or
-a Debug or Release build configuration subdirectory) and run these commands:
-
-  Tutorial 4294967296
-  Tutorial 10
-  Tutorial

-# Adding Generator Expressions #
-
-Generator expressions are evaluated during build system generation to produce
-information specific to each build configuration.
-
-Generator expressions are allowed in the context of many target properties, such
-as LINK_LIBRARIES, INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS and others. They may
-also be used when using commands to populate those properties, such as
-target_link_libraries(), target_include_directories(),
-target_compile_definitions() and others.
-
-Generator expressions may to used to enable conditional linking, conditional
-definitions used when compiling, and conditional include directories and more.
-The conditions may be based on the build configuration, target properties,
-platform information or any other queryable information.
-
-There are different types of generator expressions including Logical,
-Informational, and Output expressions.
-
-Logical expressions are used to create conditional output. The basic expressions
-are the 0 and 1 expressions. A "$<0:...>" results in the empty string, and
-"$<1:...>" results in the content of "...".  They can also be nested.
-For example:
-
-  if(HAVE_LOG AND HAVE_EXP)
-    target_compile_definitions(SqrtLibrary
-                               PRIVATE "HAVE_LOG" "HAVE_EXP")
-  endif()
-
-Can be rewritten with generator expressions:
-
-  target_compile_definitions(SqrtLibrary PRIVATE
-                             "$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>"
-                             "$<$<BOOL:${HAVE_EXP}>:HAVE_EXP>"
-                            )
-
-Note that "${HAVE_LOG}" is evaluated at CMake configure time while
-"$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>" is evaluated at build system generation time.

-# Adding Export Configuration #
-
-During Step 4 of the tutorial we added the ability for CMake to install the
-library and headers of the project. During Step 7 we added the ability
-to package up this information so it could be distributed to other people.
-
-The next step is to add the necessary information so that other CMake projects
-can use our project, be it from a build directory, a local install or when
-packaged.
-
-The first step is to update our install(TARGETS) commands to not only specify
-a DESTINATION but also an EXPORT. The EXPORT keyword generates and installs a
-CMake file containing code to import all targets listed in the install command
-from the installation tree. So let's go ahead and explicitly EXPORT the
-MathFunctions library by updating the install command in
-MathFunctions/CMakeLists.txt to look like:
-
-  install(TARGETS MathFunctions DESTINATION lib EXPORT MathFunctionsTargets)
-
-Now that we have MathFunctions being exported, we also need to explicitly install
-the generated MathFunctionsTargets.cmake file. This is done by adding
-the following to the bottom of the top-level CMakeLists.txt:
-
-  # install the configuration targets
-  install(EXPORT MathFunctionsTargets
-    FILE MathFunctionsTargets.cmake
-    DESTINATION lib/cmake/MathFunctions
-  )
-
-At this point you should try and run CMake. If everything is setup properly
-you will see that CMake will generate an error that looks like:
-
-  Target "MathFunctions" INTERFACE_INCLUDE_DIRECTORIES property contains
-  path:
-
-    "/Users/robert/Documents/CMakeClass/Tutorial/Step11/MathFunctions"
-
-  which is prefixed in the source directory.
-
-What CMake is trying to say is that during generating the export information
-it will export a path that is intrinsically tied to the current machine and
-will not be valid on other machines. The solution to this is to update the
-MathFunctions target_include_directories to understand that it needs different
-INTERFACE locations when being used from within the build directory and from an
-install / package. This means converting the target_include_directories
-call for MathFunctions to look like:
-
-  target_include_directories(MathFunctions
-                             INTERFACE
-                              $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>
-                              $<INSTALL_INTERFACE:include>
-                             )
-
-Once this has been updated, we can re-run CMake and see verify that it doesn't
-warn anymore.
-
-At this point, we have CMake properly packaging the target information that is
-required but we will still need to generate a MathFunctionsConfig.cmake, so
-that the CMake find_package command can find our project. So let's go ahead and
-add a new file to the top-level of the project called Config.cmake.in with the
-following contents:
-
-  @PACKAGE_INIT@
-
-  include ( "${CMAKE_CURRENT_LIST_DIR}/MathFunctionsTargets.cmake" )
-
-Then, to properly configure and install that file, add the following to the
-bottom of the top-level CMakeLists:
-
-  include(CMakePackageConfigHelpers)
-  # generate the config file that is includes the exports
-  configure_package_config_file(${CMAKE_CURRENT_SOURCE_DIR}/Config.cmake.in
-    "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfig.cmake"
-    INSTALL_DESTINATION "lib/cmake/example"
-    NO_SET_AND_CHECK_MACRO
-    NO_CHECK_REQUIRED_COMPONENTS_MACRO
-    )
-  # generate the version file for the config file
-  write_basic_package_version_file(
-    "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfigVersion.cmake"
-    VERSION "${Tutorial_VERSION_MAJOR}.${Tutorial_VERSION_MINOR}"
-    COMPATIBILITY AnyNewerVersion
-  )
-
-  # install the configuration file
-  install(FILES
-    ${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfig.cmake
-    DESTINATION lib/cmake/MathFunctions
-    )
-
-At this point, we have generated a relocatable CMake Configuration for our project
-that can be used after the project has been installed or packaged. If we want
-our project to also be used from a build directory we only have to add
-the following to the bottom of the top level CMakeLists:
-
-  # generate the export targets for the build tree
-  # needs to be after the install(TARGETS ) command
-  export(EXPORT MathFunctionsTargets
-    FILE "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsTargets.cmake"
-  )
-
-With this export call we now generate a Targets.cmake, allowing the configured
-MathFunctionsConfig.cmake in the build directory to be used by other projects,
-without needing it to be installed.

-# Adding a Library #
-
-Now we will add a library to our project. This library will contain our own
-implementation for computing the square root of a number. The executable can
-then use this library instead of the standard square root function provided by
-the compiler.
-
-For this tutorial we will put the library into a subdirectory
-called MathFunctions. It will have the following one line CMakeLists file:
-
-  add_library(MathFunctions mysqrt.cxx)
-
-The source file mysqrt.cxx has one function called mysqrt that provides similar
-functionality to the compiler’s sqrt function. To make use of the new library
-we add an add_subdirectory call in the top-level CMakeLists file so that the
-library will get built. We add the new library to the executable, and add the
-MathFunctions as an include directory so that mqsqrt.h header file can be
-found. The last few lines of the top-level CMakeLists file now look like:
-
-
-  add_subdirectory(MathFunctions)
-
-  #add the executable
-  add_executable(Tutorial tutorial.cxx)
-
-  target_link_libraries(Tutorial ${EXTRA_LIBS})
-
-
-Now let us make the MathFunctions library optional. While for the tutorial
-there really isn’t any need to do so, but with larger projects this is a common
-occurrence. The first step is to add an option to the top-level CMakeLists file.
-
-  option (USE_MYMATH
-          "Use tutorial provided math implementation" ON)
-
-This will show up in CMake GUI and ccmake with a default value of ON that can
-be changed by the user. This setting will be stored so that the user does not
-need to set the value each time they run CMake on this build directory.
-
-The next change is to make building and linking the MathFunctions library
-conditional. To do this we change the top-level CMakeLists file to look like
-the following:
-
-  cmake_minimum_required(VERSION 3.3)
-  project(Tutorial)
-
-  set(CMAKE_CXX_STANDARD 11)
-  set(CMAKE_CXX_STANDARD_REQUIRED True)
-
-  # the version number.
-  set(Tutorial_VERSION_MAJOR 1)
-  set(Tutorial_VERSION_MINOR 0)
-
-  # configure a header file to pass some of the CMake settings
-  # to the source code
-  configure_file(
-    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
-    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
-    )
-
-  # should we use our own math functions
-  option(USE_MYMATH "Use tutorial provided math implementation" ON)
-
-  # add the MathFunctions library?
-  if(USE_MYMATH)
-    add_subdirectory(MathFunctions)
-    list(APPEND EXTRA_LIBS MathFunctions)
-    list(APPEND EXTRA_INCLUDES "${PROJECT_SOURCE_DIR}/MathFunctions")
-  endif(USE_MYMATH)
-
-  # add the executable
-  add_executable(Tutorial tutorial.cxx)
-
-  target_link_libraries(Tutorial ${EXTRA_LIBS})
-
-  # add the binary tree to the search path for include files
-  # so that we will find TutorialConfig.h
-  target_include_directories(Tutorial PUBLIC
-                             "${PROJECT_BINARY_DIR}"
-                             ${EXTRA_INCLUDES}
-                             )
-
-Note the use of the variables EXTRA_LIBS, and EXTRA_INCLUDES to collect
-up any optional libraries to later be linked into the executable. This is a
-classic approach when dealing with many optional components, we will cover the
-modern approach in the next step. For now the corresponding changes to the
-source code are fairly straightforward and leave us with:
-
-  #ifdef USE_MYMATH
-    double outputValue = mysqrt(inputValue);
-  #else
-    double outputValue = sqrt(inputValue);
-  #endif
-
-Since the source code now requires USE_MYMATH we can add it to the
-TutorialConfig.h.in. Simply add the following line:
-  #cmakedefine USE_MYMATH
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool and then run the built Tutorial executable.
-
-Which function gives better results, Step1’s sqrt or Step2’s mysqrt?

-# Adding Usage Requirements for Library #
-
-Usage requirements allow for far better control over a library / executable's
-link and include line. While also giving more control over the transitive
-property of targets inside CMake. The primary commands that leverage usage
-requirements are:
-
-  - target_compile_definitions
-  - target_compile_options
-  - target_include_directories
-  - target_link_libraries
-
-First up is MathFunctions. We first state that anybody linking to MathFunctions
-needs to include the current source directory, while MathFunctions itself
-doesn't. So this can become an INTERFACE usage requirement.
-
-Remember INTERFACE means things that consumers require but the producer doesn't.
-
-  target_include_directories(MathFunctions
-            INTERFACE ${CMAKE_CURRENT_SOURCE_DIR})
-
-Now that we've specified usage requirements for MathFunctions we can safely remove
-our uses of the EXTRA_INCLUDES variable.
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool.

-# Installing and Testing #
-
-Now we can start adding testing support and install rules to our project.
-
-The install rules are fairly simple; for MathFunctions we install the library
-and header file, for the application we install the executable and configured
-header.
-
-So to MathFunctions/CMakeLists.txt we add:
-
-  install (TARGETS MathFunctions DESTINATION bin)
-  install (FILES MathFunctions.h DESTINATION include)
-
-And the to top-level CMakeLists.txt we add:
-
-  install(TARGETS Tutorial DESTINATION bin)
-  install(FILES "${PROJECT_BINARY_DIR}/TutorialConfig.h"
-          DESTINATION include
-          )
-
-That is all that is needed to create a basic local install of the tutorial.
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool. Then build the “install” target by typing 'make install'
-from the command line or build the INSTALL target from an IDE. This will
-install the appropriate header files, libraries, and executables.
-
-Verify that the installed Tutorial runs. Note: The CMake variable
-CMAKE_INSTALL_PREFIX is used to determine the root of where the files will
-be installed.
-
-Next let's test our application. Adding testing is an easy process. At the
-end of the top-level CMakeLists file we can add a number of basic tests to
-verify that the application is working correctly.
-
-  # enable testing
-  enable_testing()
-
-  # does the application run
-  add_test(NAME Runs COMMAND Tutorial 25)
-
-  # does the usage message work?
-  add_test(NAME Usage COMMAND Tutorial)
-  set_tests_properties(Usage
-    PROPERTIES PASS_REGULAR_EXPRESSION "Usage:.*number"
-    )
-
-  # define a function to simplify adding tests
-  function(do_test target arg result)
-    add_test(NAME Comp${arg} COMMAND ${target} ${arg})
-    set_tests_properties(Comp${arg}
-      PROPERTIES PASS_REGULAR_EXPRESSION ${result}
-      )
-  endfunction(do_test)
-
-  # do a bunch of result based tests
-  do_test(Tutorial 25 "25 is 5")
-  do_test(Tutorial -25 "-25 is [-nan|nan|0]")
-  do_test(Tutorial 0.0001 "0.0001 is 0.01")
-
-The first test simply verifies that the application runs, does not segfault or
-otherwise crash, and has a zero return value. This is the basic form of a CTest
-test.
-
-The Usage test uses a regular expression to verify that the usage message
-is printed when an incorrect number of arguments are provided.
-
-Lastly, we have a function called do_test that simplifies running the
-application and verifying that the computed square root is correct for given
-input.
-
-To run tests, cd to the binary directory and run “ctest -N” and “ctest -VV”.

-# Adding System Introspection #
-
-Let us consider adding some code to our project that depends on features the
-target platform may not have. For this example, we will add some code that
-depends on whether or not the target platform has the log and exp functions. Of
-course almost every platform has these functions but for this tutorial assume
-that they are not common.
-
-If the platform has log and exp then we will use them to compute the square
-root in the mysqrt function. We first test for the availability of these
-functions using the CheckSymbolExists.cmake macro in the top-level CMakeLists
-file as follows:
-
-  # does this system provide the log and exp functions?
-  include(CheckSymbolExists)
-  set(CMAKE_REQUIRED_LIBRARIES "m")
-  check_symbol_exists(log "math.h" HAVE_LOG)
-  check_symbol_exists(exp "math.h" HAVE_EXP)
-
-Now let's add these defines to TutorialConfig.h.in so that we can use them
-from mysqrt.cxx:
-
-  // does the platform provide exp and log functions?
-  #cmakedefine HAVE_LOG
-  #cmakedefine HAVE_EXP
-
-Modify mysqrt.cxx to include math.h. Next, in the mysqrt function we can
-provide an alternate implementation based on log and exp if they are available
-on the system using the following code:
-
-  // if we have both log and exp then use them
-  #if defined(HAVE_LOG) && defined (HAVE_EXP)
-    double result = exp(log(x)*0.5);
-    std::cout << "Computing sqrt of " << x << " to be " << result << " using log" << std::endl;
-  #else
-    ...
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool.
-
-You will notice that even though HAVE_LOG and HAVE_EXP are both defined mysqrt
-isn't using them. We should realize quickly that we have forgotten to include
-TutorialConfig.h in mysqrt.cxx. We will also need to update
-MathFunctions/CMakeLists.txt with where it is located.
-
-So let's go ahead and update MathFunctions/CMakeLists.txt to look like:
-
-  add_library(MathFunctions mysqrt.cxx)
-
-  target_include_directories(MathFunctions
-            INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
-            PRIVATE ${Tutorial_BINARY_DIR}
-            )
-
-  install(TARGETS MathFunctions DESTINATION lib)
-  install(FILES MathFunctions.h DESTINATION include)
-
-Now all we need to do is include TutorialConfig.h in mysqrt.cxx
-
-At this point you should go ahead and build the project again.
-
-Run the built Tutorial executable. Which function gives better results now,
-Step1’s sqrt or Step5’s mysqrt?
-
-Exercise: Why is it important that we configure TutorialConfig.h.in after the
-checks for HAVE_LOG and HAVE_EXP? What would happen if we inverted the two?
-
-Exercise: Is there a better place for us to save the HAVE_LOG and HAVE_EXP
-values other than in TutorialConfig.h?

-# Adding a Custom Command and Generated File #
-
-In this section we will show how you can add a generated source file into the
-build process of an application. For this example, we will create a table of
-precomputed square roots as part of the build process, and then compile that
-table into our application.
-
-To accomplish this, we first need a program that will generate the table. In the
-MathFunctions subdirectory a new source file named MakeTable.cxx will do just that.
-
-  // A simple program that builds a sqrt table
-  #include <iostream>
-  #include <fstream>
-  #include <cmath>
-
-  int main (int argc, char *argv[])
-  {
-    // make sure we have enough arguments
-    if (argc < 2) {
-      return 1;
-    }
-
-    std::ofstream fout(argv[1],std::ios_base::out);
-    const bool fileOpen = fout.is_open();
-    if(fileOpen) {
-      fout << "double sqrtTable[] = {" << std::endl;
-      for (int i = 0; i < 10; ++i) {
-        fout << sqrt(static_cast<double>(i)) << "," << std::endl;
-      }
-      // close the table with a zero
-      fout << "0};" << std::endl;
-      fout.close();
-    }
-    return fileOpen ? 0 : 1; // return 0 if wrote the file
-  }
-
-Note that the table is produced as valid C++ code and that the output filename
-is passed in as an argument.
-
-The next step is to add the appropriate commands to MathFunctions’ CMakeLists
-file to build the MakeTable executable and then run it as part of the build
-process. A few commands are needed to accomplish this, as shown below:
-
-  # first we add the executable that generates the table
-  add_executable(MakeTable MakeTable.cxx)
-
-  # add the command to generate the source code
-  add_custom_command(
-    OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-    COMMAND MakeTable ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-    DEPENDS MakeTable
-    )
-
-  # add the main library
-  add_library(MathFunctions
-              mysqrt.cxx
-              ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-              )
-
-  target_include_directories(MathFunctions
-          INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
-          PUBLIC ${Tutorial_BINARY_DIR}
-                 # add the binary tree directory to the search path for include files
-                 ${CMAKE_CURRENT_BINARY_DIR}
-          )
-
-  install(TARGETS MathFunctions DESTINATION lib)
-  install(FILES MathFunctions.h DESTINATION include)
-
-First, the executable for MakeTable is added as any other executable would be
-added. Then we add a custom command that specifies how to produce Table.h by
-running MakeTable. Next we have to let CMake know that mysqrt.cxx depends on
-the generated file Table.h. This is done by adding the generated Table.h to the
-list of sources for the library MathFunctions. We also have to add the current
-binary directory to the list of include directories so that Table.h can be
-found and included by mysqrt.cxx.
-
-Now let's use the generated table. First, modify mysqrt.cxx to include Table.h.
-Next, we can rewrite the mysqrt function to use the table:
-
-  if (x <= 0) {
-    return 0;
-  }
-
-  // use the table to help find an initial value
-  double result = x;
-  if (x >= 1 && x < 10) {
-    result = sqrtTable[static_cast<int>(x)];
-  }
-
-  // do ten iterations
-  for (int i = 0; i < 10; ++i) {
-    if (result <= 0) {
-      result = 0.1;
-    }
-    double delta = x - (result*result);
-    result = result + 0.5*delta/result;
-    std::cout << "Computing sqrt of " << x << " to be " << result << std::endl;
-  }
-
-Run cmake or cmake-gui to configure the project and then build it with your
-chosen build tool. When this project is built it will first build the MakeTable
-executable. It will then run MakeTable to produce Table.h. Finally, it will
-compile mysqrt.cxx which includes Table.h to produce the MathFunctions library.

-# Building an Installer #
-
-Next suppose that we want to distribute our project to other people so that they
-can use it. We want to provide both binary and source distributions on a variety
-of platforms. This is a little different from the install we did previously in
-the Installing and Testing section (Step 4), where we were installing the
-binaries that we had built from the source code. In this example we will be
-building installation packages that support binary installations and package
-management features. To accomplish this we will use CPack to create platform
-specific installers. Specifically we need to add a few lines to the bottom of
-our top-level CMakeLists.txt file.
-
-  include(InstallRequiredSystemLibraries)
-  set(CPACK_RESOURCE_FILE_LICENSE "${CMAKE_CURRENT_SOURCE_DIR}/License.txt")
-  set(CPACK_PACKAGE_VERSION_MAJOR "${Tutorial_VERSION_MAJOR}")
-  set(CPACK_PACKAGE_VERSION_MINOR "${Tutorial_VERSION_MINOR}")
-  include(CPack)
-
-That is all there is to it. We start by including InstallRequiredSystemLibraries.
-This module will include any runtime libraries that are needed by the project
-for the current platform. Next we set some CPack variables to where we have
-stored the license and version information for this project. The version
-information makes use of the variables we set earlier in this tutorial. Finally
-we include the CPack module which will use these variables and some other
-properties of the system you are on to setup an installer.
-
-The next step is to build the project in the usual manner and then run CPack
-on it. To build a binary distribution you would run:
-
-  cpack
-
-To create a source distribution you would type:
-
-  cpack -C CPackSourceConfig.cmake
-
-Alternatively, run “make package” or right click the Package target and
-“Build Project” from an IDE.
-
-Run the installer executable found  in the binary directory. Then run the
-installed executable and verify that it works.

-Instead, change directory to the binary tree, and then run:
- 'ctest [-VV] –D Experimental'. On Windows, build the EXPERIMENTAL target.

-Ctest will build and test the project and submit results to the Kitware public
-dashboard. The results of your dashboard will be uploaded to Kitware's public

-# Mixing Static and Shared #
-
-In this section we will show how by using the BUILD_SHARED_LIBS variable we can
-control the default behavior of add_library, and allow control over how
-libraries without an explicit type ( STATIC/SHARED/MODULE/OBJECT ) are built.
-
-To accomplish this we need to add BUILD_SHARED_LIBS to the top level
-CMakeLists.txt. We use the option command as it allows users to optionally
-select if the value should be On or Off.
-
-Next we are going to refactor MathFunctions to become a real library that
-encapsulates using mysqrt or sqrt, instead of requiring the calling code
-to do this logic. This will also mean that USE_MYMATH will not control building
-MathFuctions, but instead will control the behavior of this library.
-
-The first step is to update the starting section of the top level CMakeLists.txt
-to look like:
-
-  cmake_minimum_required(VERSION 3.3)
-  project(Tutorial)
-
-  # control where the static and shared libraries are built so that on windows
-  # we don't need to tinker with the path to run the executable
-  set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY "${PROJECT_BINARY_DIR}")
-  set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "${PROJECT_BINARY_DIR}")
-
-  set(CMAKE_CXX_STANDARD 11)
-  set(CMAKE_CXX_STANDARD_REQUIRED True)
-
-  option(BUILD_SHARED_LIBS "Build using shared libraries" ON)
-
-  # the version number.
-  set(Tutorial_VERSION_MAJOR 1)
-  set(Tutorial_VERSION_MINOR 0)
-
-  # configure a header file to pass the version number only
-  configure_file(
-    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
-    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
-    )
-
-  # add the MathFunctions library
-  add_subdirectory(MathFunctions)
-
-  # add the executable
-  add_executable(Tutorial tutorial.cxx)
-  target_link_libraries(Tutorial PUBLIC MathFunctions)
-
-Now that we have made MathFunctions always be used, we will need to update
-the logic of that library. So, in MathFunctions/CMakeLists.txt we need to
-create a SqrtLibrary that will conditionally be built when USE_MYMATH is
-enabled. Now, since this is a tutorial, we are going to explicitly require
-that SqrtLibrary is built statically.
-
-The end result is that MathFunctions/CMakeLists.txt should look like:
-
-  # add the library that runs
-  add_library(MathFunctions MathFunctions.cxx)
-
-  # state that anybody linking to us needs to include the current source dir
-  # to find MathFunctions.h, while we don't.
-  target_include_directories(MathFunctions
-                             INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
-                             )
-
-  # should we use our own math functions
-  option(USE_MYMATH "Use tutorial provided math implementation" ON)
-  if(USE_MYMATH)
-
-    # does this system provide the log and exp functions?
-    include(CheckSymbolExists)
-    set(CMAKE_REQUIRED_LIBRARIES "m")
-    check_symbol_exists(log "math.h" HAVE_LOG)
-    check_symbol_exists(exp "math.h" HAVE_EXP)
-
-    # first we add the executable that generates the table
-    add_executable(MakeTable MakeTable.cxx)
-
-    # add the command to generate the source code
-    add_custom_command(
-      OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-      COMMAND MakeTable ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-      DEPENDS MakeTable
-      )
-
-    # library that just does sqrt
-    add_library(SqrtLibrary STATIC
-                mysqrt.cxx
-                ${CMAKE_CURRENT_BINARY_DIR}/Table.h
-                )
-
-    # state that we depend on our binary dir to find Table.h
-    target_include_directories(SqrtLibrary PRIVATE
-                               ${CMAKE_CURRENT_BINARY_DIR}
-                               )
-
-    target_compile_definitions(MathFunctions PRIVATE "USE_MYMATH")
-    if(HAVE_LOG AND HAVE_EXP)
-      target_compile_definitions(SqrtLibrary
-                                 PRIVATE "HAVE_LOG" "HAVE_EXP")
-    endif()
-
-    target_link_libraries(MathFunctions PRIVATE SqrtLibrary)
-  endif()
-
-  # define the symbol stating we are using the declspec(dllexport) when
-  # building on windows
-  target_compile_definitions(MathFunctions PRIVATE "EXPORTING_MYMATH")
-
-  install(TARGETS MathFunctions DESTINATION lib)
-  install(FILES MathFunctions.h DESTINATION include)
-
-Next, update MathFunctions/mysqrt.cxx to use the mathfunctions and detail namespaces:
-
-  #include <iostream>
-  #include "MathFunctions.h"
-
-  // include the generated table
-  #include "Table.h"
-
-  #include <cmath>
-
-  namespace mathfunctions {
-  namespace detail {
-  // a hack square root calculation using simple operations
-  double mysqrt(double x)
-  {
-    ...
-
-    return result;
-  }
-  }
-  }
-
-We also need to make some changes in tutorial.cxx, so that it no longer uses USE_MYMATH:
-1. Always include MathFunctions.h
-2. Always use mathfunctions::sqrt
-
-Finally, update MathFunctions/MathFunctions.h to use dll export defines:
-
-  #if defined(_WIN32)
-  #if defined(EXPORTING_MYMATH)
-    #define DECLSPEC  __declspec(dllexport)
-  #else
-    #define DECLSPEC  __declspec(dllimport)
-  #endif
-  #else //non windows
-    #define DECLSPEC
-  #endif
-
-  namespace mathfunctions
-  {
-    double DECLSPEC sqrt(double x);
-  }
-
-At this point, if you build everything, you will notice that linking fails
-as we are combining a static library without position enabled code with a
-library that has position enabled code. This solution to this is to explicitly
-set the POSITION_INDEPENDENT_CODE target property of SqrtLibrary to be True no
-matter the build type.
-
-Exercise: We modified MathFunctions.h to use dll export defines. Using CMake
-documentation can you find a helper module to simplify this?
-
-Exercise: Determine what command is enabling PIC for SqrtLibrary.
-What happens if we remove said command?

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications

-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the

-      agreed to in writing, Licensor provides the Work (and each

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-Kitware Local Git Setup Scripts
-
-
-Introduction
-------------
-
-This is a collection of local Git development setup scripts meant for
-inclusion in project source trees to aid their development workflow.
-Project-specific information needed by the scripts may be configured
-in a "config" file added next to them in the project.
-
-
-Import
-------
-
-A project may import these scripts into their source tree by
-initializing a subtree merge.  Bring up a Git prompt and set the
-current working directory inside a clone of the target project.
-Fetch the "setup" branch from the GitSetup repository:
-
- $ git fetch ../GitSetup setup:setup
-
-Prepare to merge the branch but place the content in a subdirectory.
-Any prefix (with trailing '/') may be chosen so long as it is used
-consistently within a project through the rest of these instructions:
-
- $ git merge -s ours --no-commit setup
- $ git read-tree -u --prefix=Utilities/GitSetup/ setup
-
-Commit the merge with an informative message:
-
- $ git commit
- ------------------------------------------------------------------------
- Merge branch 'setup'
-
- Add Utilities/GitSetup/ directory using subtree merge from
- the general GitSetup repository "setup" branch.
- ------------------------------------------------------------------------
-
-Optionally add to the project ".gitattributes" file the line
-
- /Utilities/GitSetup export-ignore
-
-to exclude the GitSetup directory from inclusion by "git archive"
-since it does not make sense in source tarballs.
-
-
-Configuration
--------------
-
-Read the "Project configuration instructions" comment in each script.
-Add a "config" file next to the scripts with desired configuration
-(optionally copy and modify "config.sample").  For example, to
-configure the "setup-hooks" script:
-
- $ git config -f Utilities/GitSetup/config hooks.url "$url"
-
-where "$url" is the project repository publishing the "hooks" branch.
-When finished, add and commit the configuration file:
-
- $ git add Utilities/GitSetup/config
- $ git commit
-
-
-Update
-------
-
-A project may update these scripts from the GitSetup repository.
-Bring up a Git prompt and set the current working directory inside a
-clone of the target project.  Fetch the "setup" branch from the
-GitSetup repository:
-
- $ git fetch ../GitSetup setup:setup
-
-Merge the "setup" branch into the subtree:
-
- $ git merge -X subtree=Utilities/GitSetup setup
-
-where "Utilities/GitSetup" is the same prefix used during the import
-setup, but without a trailing '/'.
-

+CMake Release Utilities
+***********************
+
+This directory contains scripts used to package CMake itself for distribution
+on ``cmake.org``.  See also the `CMake Source Code Guide`_.
+
+.. _`CMake Source Code Guide`: ../../Help/dev/source.rst
+
+Docker
+------
+
+The ``linux/<arch>/`` directories contain Docker specifications that anyone
+may use to produce Linux binaries for CMake:
+
+* ``linux/<arch>/base/Dockerfile``:
+  Produces a base image with a build environment for portable CMake binaries.
+  This image is published in the `kitware/cmake Docker Hub Repository`_
+  with tag ``build-linux-<arch>-base-<date>``.
+
+* ``linux/<arch>/deps/Dockerfile``:
+  Produces an image with custom-built dependencies for portable CMake binaries.
+  This image is published in the `kitware/cmake Docker Hub Repository`_
+  with tag ``build-linux-<arch>-deps-<date>``.
+
+* ``linux/<arch>/Dockerfile``:
+  Produce an image containing a portable CMake binary package for Linux.
+  Build this image using the CMake source directory as the build context.
+  The resulting image will have an ``/out`` directory containing the package.
+  For example:
+
+  .. code-block:: console
+
+    $ docker build --tag=cmake:build --network none \
+        -f cmake-src/Utilities/Release/linux/$arch/Dockerfile cmake-src
+    $ docker container create --name cmake-build cmake:build
+    $ docker cp cmake-build:/out .
+    $ ls out/cmake-*-Linux-$arch.*
+
+* ``linux/<arch>/test/Dockerfile``:
+  Produces a base image with a test environment for packaged CMake binaries.
+  For example, build the test base image:
+
+  .. code-block:: console
+
+    $ docker build --tag=cmake:test-base \
+        cmake-src/Utilities/Release/linux/$arch/test
+
+  Then create a local ``test/Dockerfile`` to prepare an image with both the
+  CMake source tree and the above-built package::
+
+    FROM cmake:test-base
+    COPY cmake-src /opt/cmake/src/cmake
+    ADD out/cmake-<ver>-Linux-<arch>.tar.gz /opt/
+    ENV PATH=/opt/cmake-<ver>-Linux-<arch>/bin:$PATH
+
+  Build the test image and run it to drive testing:
+
+  .. code-block:: console
+
+    $ docker build --tag cmake:test --network none -f test/Dockerfile .
+    $ docker run --network none cmake:test bash test-make.bash
+    $ docker run --network none cmake:test bash test-ninja.bash
+
+.. _`kitware/cmake Docker Hub Repository`: https://hub.docker.com/r/kitware/cmake
+
+Scripts for Kitware
+-------------------
+
+Kitware uses the following scripts to produce binaries for ``cmake.org``.
+They work only on specific machines Kitware uses for such builds.
+
+* ``create-cmake-release.cmake``:
+  Run ``cmake -DCMAKE_CREATE_VERSION=$ver -P ../create-cmake-release.cmake``
+  to generate ``create-$ver-*.sh`` release scripts.  It also displays
+  instructions to run them.
+
+* ``*_release.cmake``:
+  Platform-specific settings used in corresponding scripts generated above.
+
+* ``release_cmake.cmake``:
+  Code shared by all ``*_release.cmake`` scripts.
+
+* ``release_cmake.sh.in``:
+  Template for script that runs on the actual build machines.
