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

+for an extended period by work in a different MR).  This is not an
+indication that there is a problem with the MR's content, it is only a
+practical measure to allow the reviewers to focus attention on MRs that
+are actively being worked on.  As a guide, the average period of inactivity
+before transitioning a MR to the expired state would be around 2 weeks,
+but this may decrease to 1 week or less when there is a high number of
+open merge requests.
+
+Reviewers would usually provide a message similar to the following when
+resolving a MR as expired::
+
+  Closing for now. @<MR-author> please re-open when ready to continue work.
+
+This is to make it clear to contributors that they are welcome to re-open
+the expired MR when they are ready to return to working on it and moving
+it forward.  In the meantime, the MR will appear as ``Closed`` in GitLab,
+but it can be differentiated from permanently closed MRs by the presence
+of the ``workflow:expired`` label.
+
+**NOTE:** Please re-open *before* pushing an update to the MR topic branch
+to ensure GitLab will still act on the association.  If changes are pushed
+before re-opening the MR, the reviewer should initiate a ``Do: check`` to
+force GitLab to act on the updates.
+
+External Discussion
+-------------------
+
+In some situations, a series of comments on a MR may develop into a more
+involved discussion, or it may become apparent that there are broader
+discussions that need to take place before the MR can move forward in an
+agreed direction.  Such discussions are better suited to GitLab issues
+rather than in a MR because MRs may be superseded by a different MR, or
+the set of changes may evolve to look quite different to the context in
+which the discussions began.  When this occurs, reviewers may ask the
+MR author to open an issue to discuss things there and they will transition
+the MR to a resolved state with the label ``workflow:external-discussion``.
+The MR will appear in GitLab as closed, but it can be differentiated from
+permanently closed MRs by the presence of the ``workflow:external-discussion``
+label.  Reviewers should leave a message clearly explaining the action
+so that the MR author understands that the MR closure is temporary and
+it is clear what actions need to happen next.  The following is an example
+of such a message, but it will usually be necessary to tailor the message
+to the individual situation::
+
+  The desired behavior here looks to be more involved than first thought.
+  Please open an issue so we can discuss the relevant details there.
+  Once the path forward is clear, we can re-open this MR and continue work.
+
+When the discussion in the associated issue runs its course and the way

+or :command:`enable_language` command.  The policy must be set prior

+MSVC runtime library flags are selected by an abstraction.
+
+Compilers targeting the MSVC ABI have flags to select the MSVC runtime library.
+Runtime library selection typically varies with build configuration because
+there is a separate runtime library for Debug builds.
+
+In CMake 3.14 and below, MSVC runtime library selection flags are added to
+the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache entries by CMake
+automatically.  This allows users to edit their cache entries to adjust the
+flags.  However, the presence of such default flags is problematic for
+projects that want to choose a different runtime library programmatically.
+In particular, it requires string editing of the
+:variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` variables with knowledge of the
+CMake builtin defaults so they can be replaced.
+
+CMake 3.15 and above prefer to leave the MSVC runtime library selection flags
+out of the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` values and instead
+offer a first-class abstraction.  The :variable:`CMAKE_MSVC_RUNTIME_LIBRARY`
+variable and :prop_tgt:`MSVC_RUNTIME_LIBRARY` target property may be set to
+select the MSVC runtime library.
+
+This policy provides compatibility with projects that have not been updated
+to be aware of the abstraction.  The policy setting takes effect as of the
+first :command:`project` or :command:`enable_language` command that enables
+a language whose compiler targets the MSVC ABI.
+
+.. note::
+
+  Once the policy has taken effect at the top of a project, that choice
+  must be used throughout the tree.  In projects that have nested projects
+  in subdirectories, be sure to convert everything together.
+
+The ``OLD`` behavior for this policy is to place MSVC runtime library
+flags in the default :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache

+The ``NEW`` behavior for this policy is to *not* place MSVC runtime

+A property on a directory that indicates if its targets are excluded

+
+Targets inherit the :prop_tgt:`EXCLUDE_FROM_ALL` property from the directory
+that they are created in. When a directory is excluded, all of its targets will
+have :prop_tgt:`EXCLUDE_FROM_ALL` set to ``TRUE``. After creating such a target
+you can change its :prop_tgt:`EXCLUDE_FROM_ALL` property to ``FALSE``. This
+will cause the target to be included in the default build target.

+Qt version detection
+^^^^^^^^^^^^^^^^^^^^
+
+:prop_tgt:`AUTOMOC` enabled targets need to know the Qt major and minor
+version they're working with.  The major version usually is provided by the
+``INTERFACE_QT_MAJOR_VERSION`` property of the ``Qt[45]Core`` library,
+that the target links to.  To find the minor version, CMake builds a list of
+available Qt versions from
+
+- ``Qt5Core_VERSION_MAJOR`` and ``Qt5Core_VERSION_MINOR`` variables
+  (usually set by ``find_package(Qt5...)``)
+- ``Qt5Core_VERSION_MAJOR`` and ``Qt5Core_VERSION_MINOR`` directory properties
+- ``QT_VERSION_MAJOR`` and ``QT_VERSION_MINOR``  variables
+  (usually set by ``find_package(Qt4...)``)
+- ``QT_VERSION_MAJOR`` and ``QT_VERSION_MINOR``  directory properties
+
+in the context of the :command:`add_executable` or :command:`add_library` call.
+
+Assumed  ``INTERFACE_QT_MAJOR_VERSION`` is a valid number, the first
+entry in the list with a matching major version is taken.  If no matching major
+version was found, an error is generated.
+If  ``INTERFACE_QT_MAJOR_VERSION`` is not a valid number, the first
+entry in the list is taken.
+
+A ``find_package(Qt[45]...)`` call sets the ``QT/Qt5Core_VERSION_MAJOR/MINOR``
+variables.  If the call is in a different context than the
+:command:`add_executable` or :command:`add_library` call, e.g. in a function,
+then the version variables might not be available to the :prop_tgt:`AUTOMOC`
+enabled target.
+In that case the version variables can be forwarded from the
+`find_package(Qt[45]...)` calling context to the :command:`add_executable`
+or :command:`add_library` calling context as directory properties.
+The following Qt5 example demonstrates the procedure.
+
+.. code-block:: cmake
+
+  function (add_qt5_client)
+    find_package(Qt5 REQUIRED QUIET COMPONENTS Core Widgets)
+    ...

+CMake 3.15 Release Notes
+************************
+
+.. only:: html
+
+  .. contents::
+
+Changes made since CMake 3.14 include the following.
+
+New Features
+============
+
+Generators
+----------
+
+* The :generator:`Xcode` generator now supports per-target schemes.
+  See the :variable:`CMAKE_XCODE_GENERATE_SCHEME` variable and
+  :prop_tgt:`XCODE_GENERATE_SCHEME` target property.
+
+* The :generator:`Green Hills MULTI` generator has been updated:
+
+  * It now supports the :command:`add_custom_command` and
+    :command:`add_custom_target` commands.
+
+  * It is now available on Linux.
+
+Languages
+---------
+
+* Preliminary support for the ``Swift`` language was added to the
+  :generator:`Ninja` generator:
+
+  * Use the :envvar:`SWIFTC` environment variable to specify a compiler.
+
+  * The :prop_tgt:`Swift_DEPENDENCIES_FILE` target property and
+    :prop_sf:`Swift_DEPENDENCIES_FILE` source file property were added
+    to customize dependency files.
+
+  * The :prop_tgt:`Swift_MODULE_NAME` target property was added to
+    customize the Swift module name.
+
+  * The :prop_sf:`Swift_DIAGNOSTICS_FILE` source property was added to
+    indicate where to write the serialised Swift diagnostics.
+
+  The Swift support is experimental, not considered stable, and may change
+  in future releases of CMake.
+
+Compilers
+---------
+
+* The ``Clang`` compiler variant on Windows that targets the MSVC ABI
+  but has a GNU-like command line is now supported.
+
+* Support for the Clang-based ARM compiler was added with compiler id
+  ``ARMClang``.
+
+* Support was added for the IAR compiler architectures Renesas RX,
+  RL78, RH850 and Texas Instruments MSP430.
+
+* Support was added for the IAR compilers built for Linux (IAR BuildLx).
+
+Command-Line
+------------
+
+* The :envvar:`CMAKE_GENERATOR` environment variable was added
+  to specify a default generator to use when :manual:`cmake(1)` is
+  run without a ``-G`` option.  Additionally, environment variables
+  :envvar:`CMAKE_GENERATOR_PLATFORM`, :envvar:`CMAKE_GENERATOR_TOOLSET`,
+  and :envvar:`CMAKE_GENERATOR_INSTANCE` were created to configure
+  the generator.
+
+* The :manual:`cmake(1)` ``--build`` tool ``--target`` parameter gained support
+  for multiple targets, e.g. ``cmake --build . --target Library1 Library2``.
+  It now also has a short form ``-t`` alias, e.g.
+  ``cmake --build . -t Library1 Library2``.
+
+* The :manual:`cmake(1)` command gained a new ``--install`` option.
+  This may be used after building a project to run installation without
+  using the generated build system or the native build tool.
+
+* The :manual:`cmake(1)` command learned a new CLI option ``--loglevel``.
+
+* The :manual:`cmake(1)` ``-E remove_directory`` command-line tool learned
+  to support removing multiple directories.
+
+* The :manual:`cmake(1)` ``-E tar`` tool has been improved:
+
+  * It now continues adding files to an archive even if some of the files
+    are not readable.  This behavior is more consistent with the
+    classic ``tar`` tool.
+
+  * It now parses all flags, and if an invalid flag was provided, a
+    warning is issued.
+
+  * It now displays an error if no action flag was specified, along with a
+    list of possible actions: ``t`` (list), ``c`` (create) or ``x`` (extract).
+
+  * It now supports extracting (``-x``) or listing (``-t``) only specific
+    files or directories.
+
+  * It now supports Zstandard compression with a ``--zstd`` option.
+    Zstandard was designed to give a compression ratio comparable to that
+    of the DEFLATE (zip) algorithm, but faster, especially for decompression.
+
+Commands
+--------
+
+* The :command:`add_custom_command` and :command:`add_custom_target` commands
+  gained a new ``JOB_POOL`` option that works with the :generator:`Ninja`
+  generator to set the pool variable on the build statement.
+
+* The :command:`add_library` command ``ALIAS`` option learned to support
+  import libraries of the ``UNKNOWN`` type.
+
+* The :command:`cmake_parse_arguments` command gained an additional
+  ``<prefix>_KEYWORDS_MISSING_VALUES`` output variable to report
+  keyword arguments that were given by the caller with no values.
+
+* The :command:`execute_process` command gained a ``COMMAND_ECHO`` option
+  and supporting :variable:`CMAKE_EXECUTE_PROCESS_COMMAND_ECHO` variable
+  to enable echoing of the command-line string before execution.
+
+* The :command:`file(INSTALL)` command learned a new argument,
+  ``FOLLOW_SYMLINK_CHAIN``, which can be used to recursively resolve and
+  install symlinks.
+
+* :command:`list` learned new sub-commands:
+  ``PREPEND``, ``POP_FRONT`` and ``POP_BACK``.
+
+* The :command:`message` command learned new types:
+  ``NOTICE``, ``VERBOSE``, ``DEBUG`` and ``TRACE``.
+
+* The :command:`string` learned a new sub-command ``REPEAT``.
+
+Variables
+---------
+
+* The :variable:`CMAKE_CROSSCOMPILING_EMULATOR` variable and corresponding
+  :prop_tgt:`CROSSCOMPILING_EMULATOR` target property learned to support
+  arguments to the emulator.
+
+* The :variable:`CMAKE_FIND_PACKAGE_PREFER_CONFIG` variable was added to tell
+  :command:`find_package` calls to look for a package configuration
+  file first even if a find module is available.
+
+* The :variable:`CMAKE_FRAMEWORK` variable was added to initialize the
+  :prop_tgt:`FRAMEWORK` property on all targets.
+
+* The :variable:`CMAKE_VS_JUST_MY_CODE_DEBUGGING` variable and
+  :prop_tgt:`VS_JUST_MY_CODE_DEBUGGING` target property were added to
+  enable the Just My Code feature of the Visual Studio Debugger when
+  compiling with MSVC cl 19.05 and higher.
+
+* The :variable:`CMAKE_MSVC_RUNTIME_LIBRARY` variable and
+  :prop_tgt:`MSVC_RUNTIME_LIBRARY` target property were introduced to
+  select the runtime library used by compilers targeting the MSVC ABI.
+  See policy :policy:`CMP0091`.
+
+* The :variable:`CMAKE_PROJECT_INCLUDE` and
+  :variable:`CMAKE_PROJECT_INCLUDE_BEFORE` variables were added to allow
+  injection of custom code at the sites of :command:`project` calls
+  without knowing the project name a priori.
+
+Properties
+----------
+
+* The :prop_tgt:`ADDITIONAL_CLEAN_FILES` target property and
+  :prop_dir:`ADDITIONAL_CLEAN_FILES` directory property were added.
+  They allow to register additional files that should be removed during
+  the clean stage.
+
+* The :prop_tgt:`PUBLIC_HEADER` and :prop_tgt:`PRIVATE_HEADER` properties
+  may now be set on :ref:`Interface Libraries`. The headers specified by those
+  properties can be installed using the :command:`install(TARGETS)` command by
+  passing the ``PUBLIC_HEADER`` and ``PRIVATE_HEADER`` arguments respectively.
+
+* The :prop_tgt:`VS_PACKAGE_REFERENCES` target property was added to
+  tell :ref:`Visual Studio Generators` to add references to ``nuget``
+  packages.
+
+* The :prop_tgt:`VS_PROJECT_IMPORT` target property was added to allow
+  managed Visual Studio project files to import external ``.props`` files.
+
+* The :prop_tgt:`VS_NO_SOLUTION_DEPLOY` target property was added to
+  tell :ref:`Visual Studio Generators` whether to deploy an artifact
+  to the WinCE or Windows Phone target device.
+
+Modules
+-------
+
+* The :module:`FindBoost` module was reworked to expose a more consistent
+  user experience between its "Config" and "Module" modes and with other
+  find modules in general.
+
+  * A new imported target ``Boost::headers`` is now defined (same
+    as ``Boost::boost``).
+
+  * New output variables ``Boost_VERSION_MACRO``,
+    ``Boost_VERSION_MAJOR``, ``Boost_VERSION_MINOR``,
+    ``Boost_VERSION_PATCH``, and ``Boost_VERSION_COUNT``
+    were added.
+
+  * The ``QUIET`` argument passed to :command:`find_package` is no
+    longer ignored in config mode.  Note that the CMake package shipped with
+    Boost ``1.70.0`` ignores the ``QUIET`` argument passed to
+    :command:`find_package`.  This is fixed in the next Boost release.
+
+  * The input switch ``Boost_DETAILED_FAILURE_MSG`` was removed.
+
+  * ``Boost_VERSION`` now reports the version in ``x.y.z``
+    format in module mode.  See policy :policy:`CMP0093`.
+
+* The :module:`FindCups` module now provides imported targets.
+
+* The :module:`FindEnvModules` module was added to use Lua- and TCL-based
+  environment modules in :ref:`CTest Scripts <CTest Script>`.
+
+* The :module:`FindGLEW` module now provides an interface more consistent
+  with what upstream GLEW provides in its own CMake package files.
+
+* The :module:`FindPkgConfig` now populates :prop_tgt:`INTERFACE_LINK_OPTIONS`
+  property of imported targets with other (non-library) linker flags.
+
+* The :module:`FindPostgreSQL` module learned to find debug and release
+  variants separately.
+
+* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
+  gained additional lookup strategies and controls, and a new default.
+  See policy :policy:`CMP0094`.
+
+* Modules :module:`FindPython`, :module:`FindPython2` and :module:`FindPython3`
+  gain a new target (respectively ``Python::Module``, ``Python2::Module``
+  and ``Python3::Module``) which can be used to develop Python modules.
+
+* Modules :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
+  gain capability to control how virtual environments are handled.
+
+* The :module:`UseSWIG` module learned to manage alternate library names
+  by passing ``-interface <library_name>`` for ``python`` language or
+  ``-dllimport <library_name>`` for ``CSharp`` language to the ``SWIG``
+  compiler.

+---------------------
+
+* The :manual:`generator expressions <cmake-generator-expressions(7)>`
+  ``C_COMPILER_ID``, ``CXX_COMPILER_ID``, ``CUDA_COMPILER_ID``,
+  ``Fortran_COMPILER_ID``, ``COMPILE_LANGUAGE``, ``COMPILE_LANG_AND_ID``, and
+  ``PLATFORM_ID`` learned to support matching one value from a comma-separated
+  list.
+
+* The ``$<CUDA_COMPILER_ID:...>`` and ``$<CUDA_COMPILER_VERSION:...>``
+  :manual:`generator expressions <cmake-generator-expressions(7)>` were added.
+
+* The ``$<COMPILE_LANG_AND_ID:...>`` generator expression was introduced to
+  allow specification of compile options for target files based on the
+  :variable:`CMAKE_<LANG>_COMPILER_ID` and :prop_sf:`LANGUAGE` of
+  each source file.
+
+* A ``$<FILTER:list,INCLUDE|EXCLUDE,regex>``
+  :manual:`generator expression <cmake-generator-expressions(7)>`
+  has been added.
+
+* A ``$<REMOVE_DUPLICATES:list>``
+  :manual:`generator expression <cmake-generator-expressions(7)>`
+  has been added.
+
+* The ``$<SHELL_PATH:...>`` :manual:`generator expression
+  <cmake-generator-expressions(7)>` gained support for a list of paths.
+
+* New ``$<TARGET_FILE*>`` :manual:`generator expressions
+  <cmake-generator-expressions(7)>` were added to retrieve the prefix, base
+  name, and suffix of the file names of various artifacts:
+
+  * ``$<TARGET_FILE_PREFIX:...>``
+  * ``$<TARGET_FILE_BASE_NAME:...>``
+  * ``$<TARGET_FILE_SUFFIX:...>``
+  * ``$<TARGET_LINKER_FILE_PREFIX:...>``
+  * ``$<TARGET_LINKER_FILE_BASE_NAME:...>``
+  * ``$<TARGET_LINKER_FILE_SUFFIX:...>``
+  * ``$<TARGET_PDB_FILE_BASE_NAME:...>``
+
+* The ``$<TARGET_OBJECTS:...>`` :manual:`generator expression
+  <cmake-generator-expressions(7)>` is now supported on ``SHARED``,
+  ``STATIC``, ``MODULE`` libraries and executables.
+
+CTest
+-----
+
+* The :command:`ctest_submit` command learned a new option: ``BUILD_ID``.
+  This can be used to store the ID assigned to this build by CDash to a
+  variable.
+
+* The :command:`ctest_update` command learned to honor a new variable:
+  :variable:`CTEST_UPDATE_VERSION_OVERRIDE`. This can be used to specify
+  the current version of your source tree rather than using the update
+  command to discover the current version that is checked out.
+
+CPack
+-----
+
+* The :cpack_gen:`CPack IFW Generator` gained a new
+  :variable:`CPACK_IFW_PACKAGE_STYLE_SHEET` variable to customize the
+  installer stylesheet.
+
+Deprecated and Removed Features
+===============================
+
+* The :manual:`cmake-server(7)` mode has been deprecated and will be
+  removed from a future version of CMake.  Please port clients to use
+  the :manual:`cmake-file-api(7)` instead.
+
+* The :prop_dir:`ADDITIONAL_MAKE_CLEAN_FILES` directory property is now
+  deprecated.  Use the :prop_dir:`ADDITIONAL_CLEAN_FILES` directory property
+  instead.
+
+* The variable :variable:`CMAKE_AUTOMOC_RELAXED_MODE` is considered
+  deprecated.  Support still exists but will be removed in future versions.
+
+* The :command:`export(PACKAGE)` command now does nothing unless
+  enabled via :variable:`CMAKE_EXPORT_PACKAGE_REGISTRY`.
+  See policy :policy:`CMP0090`.
+
+* The :generator:`Xcode` generator now requires at least Xcode 5.
+
+* An explicit deprecation diagnostic was added for policy ``CMP0066``
+  (``CMP0065`` 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.
+
+Other Changes
+=============
+
+* CMake learned how to compile C++14 with the IBM AIX XL compiler
+  and the SunPro compiler and to compile C++20 with the AppleClang compiler.
+
+* With MSVC-like compilers the value of :variable:`CMAKE_<LANG>_FLAGS`
+  no longer contains warning flags like ``/W3`` by default.
+  See policy :policy:`CMP0092`.
+
+* IBM Clang-based XL compilers that define ``__ibmxl__`` now use the
+  compiler id ``XLClang`` instead of ``XL``.  See policy :policy:`CMP0089`.
+
+* The :command:`file(REMOVE)` and :command:`file(REMOVE_RECURSE)` commands
+  were changed to ignore empty arguments with a warning instead of treating
+  them as a relative path and removing the contents of the current directory.

+FindEnvModules
+--------------
+
+Locate an environment module implementation and make commands available to
+CMake scripts to use them.  This is compatible with both Lua-based Lmod
+and TCL-based EnvironmentModules.
+
+This module is intended for the use case of setting up the compiler and library
+environment within a :ref:`CTest Script <CTest Script>` (``ctest -S``).  It can
+also be used in a :ref:`CMake Script <Script Processing Mode>` (``cmake -P``).
+
+.. note::
+
+  The loaded environment will not survive past the end of the calling process.
+  Do not use this module in project code (``CMakeLists.txt`` files) to load
+  a compiler environment; it will not be available during the build.  Instead
+  load the environment manually before running CMake or using the generated
+  build system.
+
+Example Usage
+^^^^^^^^^^^^^
+
+.. code-block:: cmake
+
+  set(CTEST_BUILD_NAME "CrayLinux-CrayPE-Cray-dynamic")
+  set(CTEST_BUILD_CONFIGURATION Release)
+  set(CTEST_BUILD_FLAGS "-k -j8")
+  set(CTEST_CMAKE_GENERATOR "Unix Makefiles")
+
+  ...
+
+  find_package(EnvModules REQUIRED)
+
+  env_module(purge)
+  env_module(load modules)
+  env_module(load craype)
+  env_module(load PrgEnv-cray)
+  env_module(load craype-knl)
+  env_module(load cray-mpich)
+  env_module(load cray-libsci)
+
+  set(ENV{CRAYPE_LINK_TYPE} dynamic)
+
+  ...
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``EnvModules_FOUND``
+  True if a compatible environment modules framework was found.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variable will be set:
+
+``EnvModules_COMMAND``
+  The low level module command to use.  Currently supported
+  implementations are the Lua based Lmod and TCL based EnvironmentModules.
+
+Environment Variables
+^^^^^^^^^^^^^^^^^^^^^
+
+``ENV{MODULESHOME}``
+  Usually set by the module environment implementation, used as a hint to
+  locate the module command to execute.
+
+Provided Functions
+^^^^^^^^^^^^^^^^^^
+
+This defines the following CMake functions for interacting with environment
+modules:
+
+.. command:: env_module
+
+  Execute an aribitrary module command:
+
+  .. code-block:: cmake
+
+    env_module(cmd arg1 ... argN)
+    env_module(
+      COMMAND cmd arg1 ... argN
+      [OUTPUT_VARIABLE <out-var>]
+      [RESULT_VARIABLE <ret-var>]
+    )
+
+  The options are:
+
+  ``cmd arg1 ... argN``
+    The module sub-command and arguments to execute as if they were
+    passed directly to the module command in your shell environment.
+
+  ``OUTPUT_VARIABLE <out-var>``
+    The standard output from executing the module command.
+
+  ``RESULT_VARIABLE <ret-var>``
+    The return code from executing the module command.
+
+.. command:: env_module_swap
+
+  Swap one module for another:
+
+  .. code-block:: cmake
+
+    env_module_swap(out_mod in_mod
+      [OUTPUT_VARIABLE <out-var>]
+      [RESULT_VARIABLE <ret-var>]
+    )
+
+  This is functionally equivalent to the ``module swap out_mod in_mod`` shell
+  command.  The options are:
+
+  ``OUTPUT_VARIABLE <out-var>``
+    The standard output from executing the module command.
+
+  ``RESULT_VARIABLE <ret-var>``
+    The return code from executing the module command.
+
+.. command:: env_module_list
+
+  Retrieve the list of currently loaded modules:
+
+  .. code-block:: cmake
+
+    env_module_list(<out-var>)
+
+  This is functionally equivalent to the ``module list`` shell command.
+  The result is stored in ``<out-var>`` as a properly formatted CMake
+  :ref:`semicolon-separated list <CMake Language Lists>` variable.
+
+.. command:: env_module_avail
+
+  Retrieve the list of available modules:
+
+  .. code-block:: cmake
+
+    env_module_avail([<mod-prefix>] <out-var>)
+
+  This is functionally equivalent to the ``module avail <mod-prefix>`` shell
+  command.  The result is stored in ``<out-var>`` as a properly formatted
+  CMake :ref:`semicolon-separated list <CMake Language Lists>` variable.

-Additional search locations can be specified after the PATHS argument.
+searched for is specified by the names listed after ``NAMES`` argument.
+Additional search locations can be specified after the ``PATHS`` argument.
 If you require special a version of a jar file you can specify it with
-the VERSIONS argument.  The argument after DOC will be used for the
+the ``VERSIONS`` argument.  The argument after ``DOC`` will be used for the
 documentation string in the cache.

-
- install_jar(target_name destination)
- install_jar(target_name DESTINATION destination [COMPONENT component])
-
-This command installs the TARGET_NAME files to the given DESTINATION.
-It should be called in the same scope as add_jar() or it will fail.
-
-Target Properties:
-
-::
-
-   The install_jar() function sets the INSTALL_DESTINATION target property
-   on jars so installed. This property holds the DESTINATION as described
-   above, and is used by install_jar_exports(). You can get this property
-   with the
-      get_property(TARGET <target_name> PROPERTY INSTALL_DESTINATION)

+
+# This CMake configuration file, installed as part of the Boost build
+# and installation procedure done by `b2 install`, provides support
+# for find_package(Boost).
+#
+# It's roughly, but not perfectly, compatible with the behavior
+# of find_package(Boost) as provided by FindBoost.cmake.
+#
+# A typical use might be
+#
+# find_package(Boost 1.70 REQUIRED COMPONENTS filesystem regex PATHS C:/Boost)
+#
+# On success, the above invocation would define the targets Boost::headers,
+# Boost::filesystem and Boost::regex. Boost::headers represents all
+# header-only libraries. An alias, Boost::boost, for Boost::headers is
+# provided for compatibility.
+#
+# Since Boost libraries can coexist in many variants - 32/64 bit,
+# static/dynamic runtime, debug/release, the following variables can be used
+# to control which variant is chosen:
+#
+# Boost_USE_DEBUG_LIBS:     When OFF, disables debug libraries.
+# Boost_USE_RELEASE_LIBS:   When OFF, disables release libraries.
+# Boost_USE_STATIC_LIBS:    When ON, uses static Boost libraries; when OFF,
+#                           uses shared Boost libraries; when not set, the
+#                           default is to use shared when BUILD_SHARED_LIBS is
+#                           ON, static otherwise.
+# Boost_USE_STATIC_RUNTIME: When ON, uses Boost libraries linked against the
+#                           static runtime. The default is shared runtime.
+# Boost_USE_DEBUG_RUNTIME:  When ON, uses Boost libraries linked against the
+#                           debug runtime. When OFF, against the release
+#                           runtime. The default is to use either.
+# Boost_COMPILER:           The compiler that has been used to build Boost,
+#                           such as vc141, gcc7, clang37. The default is
+#                           determined from CMAKE_CXX_COMPILER_ID.

-/*-
- * Algorithm from "A Technique for High Performance Data Compression",
- * Terry A. Welch, IEEE Computer Vol 17, No 6 (June 1984), pp 8-19.
- *
- * Usage: compress [-dfvc] [-b bits] [file ...]
- * Inputs:
- *	-d:	    If given, decompression is done instead.
- *
- *      -c:         Write output on stdout, don't remove original.
- *
- *      -b:         Parameter limits the max number of bits/code.
- *
- *	-f:	    Forces output file to be generated, even if one already
- *		    exists, and even if no space is saved by compressing.
- *		    If -f is not used, the user will be prompted if stdin is
- *		    a tty, otherwise, the output file will not be overwritten.
- *
- *      -v:	    Write compression statistics
- *
- * 	file ...:   Files to be compressed.  If none specified, stdin
- *		    is used.
- * Outputs:
- *	file.Z:	    Compressed form of file with same mode, owner, and utimes
- * 	or stdout   (if stdin used as input)
- *
- * Assumptions:
- *	When filenames are given, replaces with the compressed version
- *	(.Z suffix) only if the file decreases in size.
- * Algorithm:
- * 	Modified Lempel-Ziv method (LZW).  Basically finds common
- * substrings and replaces them with a variable size code.  This is
- * deterministic, and can be done on the fly.  Thus, the decompression
- * procedure needs no input table, but tracks the way the table was built.

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

+
+__Zstandard__, or `zstd` as short version, is a fast lossless compression algorithm,
+targeting real-time compression scenarios at zlib-level and better compression ratios.
+It's backed by a very fast entropy stage, provided by [Huff0 and FSE library](https://github.com/Cyan4973/FiniteStateEntropy).
+
+The project is provided as an open-source dual [BSD](LICENSE) and [GPLv2](COPYING) licensed **C** library,
+and a command line utility producing and decoding `.zst`, `.gz`, `.xz` and `.lz4` files.
+Should your project require another programming language,
+a list of known ports and bindings is provided on [Zstandard homepage](http://www.zstd.net/#other-languages).

+
+Zstd can also offer stronger compression ratios at the cost of compression speed.
+Speed vs Compression trade-off is configurable by small increments.
+Decompression speed is preserved and remains roughly the same at all settings,
+a property shared by most LZ compression algorithms, such as [zlib] or lzma.
+
+The following tests were run
+on a server running Linux Debian (`Linux version 4.14.0-3-amd64`)
+with a Core i7-6700K CPU @ 4.0GHz,
+using [lzbench], an open-source in-memory benchmark by @inikep
+compiled with [gcc] 7.3.0,
+on the [Silesia compression corpus].
+
+Compression Speed vs Ratio | Decompression Speed
+---------------------------|--------------------
+![Compression Speed vs Ratio](doc/images/CSpeed2.png "Compression Speed vs Ratio") | ![Decompression Speed](doc/images/DSpeed3.png "Decompression Speed")
+
+A few other algorithms can produce higher compression ratios at slower speeds, falling outside of the graph.
+For a larger picture including slow modes, [click on this link](doc/images/DCspeed5.png).
+
+
+## The case for Small Data compression
+
+Previous charts provide results applicable to typical file and stream scenarios (several MB). Small data comes with different perspectives.
+
+The smaller the amount of data to compress, the more difficult it is to compress. This problem is common to all compression algorithms, and reason is, compression algorithms learn from past data how to compress future data. But at the beginning of a new data set, there is no "past" to build upon.
+
+To solve this situation, Zstd offers a __training mode__, which can be used to tune the algorithm for a selected type of data.
+Training Zstandard is achieved by providing it with a few samples (one file per sample). The result of this training is stored in a file called "dictionary", which must be loaded before compression and decompression.
+Using this dictionary, the compression ratio achievable on small data improves dramatically.
+
+The following example uses the `github-users` [sample set](https://github.com/facebook/zstd/releases/tag/v1.1.3), created from [github public API](https://developer.github.com/v3/users/#get-all-users).
+It consists of roughly 10K records weighing about 1KB each.
+
+Compression Ratio | Compression Speed | Decompression Speed
+------------------|-------------------|--------------------
+![Compression Ratio](doc/images/dict-cr.png "Compression Ratio") | ![Compression Speed](doc/images/dict-cs.png "Compression Speed") | ![Decompression Speed](doc/images/dict-ds.png "Decompression Speed")
+
+
+These compression gains are achieved while simultaneously providing _faster_ compression and decompression speeds.
+
+Training works if there is some correlation in a family of small data samples. The more data-specific a dictionary is, the more efficient it is (there is no _universal dictionary_).
+Hence, deploying one dictionary per type of data will provide the greatest benefits.
+Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm will gradually use previously decoded content to better compress the rest of the file.
+
+### Dictionary compression How To:
+
+1. Create the dictionary
+
+   `zstd --train FullPathToTrainingSet/* -o dictionaryName`
+
+2. Compress with dictionary
+
+   `zstd -D dictionaryName FILE`
+
+3. Decompress with dictionary
+
+   `zstd -D dictionaryName --decompress FILE.zst`
+
+
+## Build instructions
+
+### Makefile
+
+If your system is compatible with standard `make` (or `gmake`),
+invoking `make` in root directory will generate `zstd` cli in root directory.
+
+Other available options include:
+- `make install` : create and install zstd cli, library and man pages
+- `make check` : create and run `zstd`, tests its behavior on local platform
+
+### cmake
+
+A `cmake` project generator is provided within `build/cmake`.
+It can generate Makefiles or other build scripts
+to create `zstd` binary, and `libzstd` dynamic and static libraries.
+
+By default, `CMAKE_BUILD_TYPE` is set to `Release`.
+
+### Meson
+
+A Meson project is provided within [`build/meson`](build/meson). Follow
+build instructions in that directory.
+
+You can also take a look at [`.travis.yml`](.travis.yml) file for an
+example about how Meson is used to build this project.
+
+Note that default build type is **release**.
+
+### Visual Studio (Windows)
+
+Going into `build` directory, you will find additional possibilities:
+- Projects for Visual Studio 2005, 2008 and 2010.
+  + VS2010 project is compatible with VS2012, VS2013, VS2015 and VS2017.
+- Automated build scripts for Visual compiler by [@KrzysFR](https://github.com/KrzysFR), in `build/VS_scripts`,
+  which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.
+
+### Buck
+
+You can build the zstd binary via buck by executing: `buck build programs:zstd` from the root of the repo.
+The output binary will be in `buck-out/gen/programs/`.
+
+## Status
+
+Zstandard is currently deployed within Facebook. It is used continuously to compress large amounts of data in multiple formats and use cases.
+Zstandard is considered safe for production environments.

+Tutorial :
+----------
+The first step is to count all symbols. FSE_count() does this job very fast.
+Result will be saved into 'count', a table of unsigned int, which must be already allocated, and have 'maxSymbolValuePtr[0]+1' cells.
+'src' is a table of bytes of size 'srcSize'. All values within 'src' MUST be <= maxSymbolValuePtr[0]
+maxSymbolValuePtr[0] will be updated, with its real value (necessarily <= original value)
+FSE_count() will return the number of occurrence of the most frequent symbol.
+This can be used to know if there is a single symbol within 'src', and to quickly evaluate its compressibility.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+The next step is to normalize the frequencies.
+FSE_normalizeCount() will ensure that sum of frequencies is == 2 ^'tableLog'.
+It also guarantees a minimum of 1 to any Symbol with frequency >= 1.
+You can use 'tableLog'==0 to mean "use default tableLog value".
+If you are unsure of which tableLog value to use, you can ask FSE_optimalTableLog(),
+which will provide the optimal valid tableLog given sourceSize, maxSymbolValue, and a user-defined maximum (0 means "default").
+
+The result of FSE_normalizeCount() will be saved into a table,
+called 'normalizedCounter', which is a table of signed short.
+'normalizedCounter' must be already allocated, and have at least 'maxSymbolValue+1' cells.
+The return value is tableLog if everything proceeded as expected.
+It is 0 if there is a single symbol within distribution.
+If there is an error (ex: invalid tableLog value), the function will return an ErrorCode (which can be tested using FSE_isError()).
+
+'normalizedCounter' can be saved in a compact manner to a memory area using FSE_writeNCount().
+'buffer' must be already allocated.
+For guaranteed success, buffer size must be at least FSE_headerBound().
+The result of the function is the number of bytes written into 'buffer'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError(); ex : buffer size too small).
+
+'normalizedCounter' can then be used to create the compression table 'CTable'.
+The space required by 'CTable' must be already allocated, using FSE_createCTable().
+You can then use FSE_buildCTable() to fill 'CTable'.
+If there is an error, both functions will return an ErrorCode (which can be tested using FSE_isError()).
+
+'CTable' can then be used to compress 'src', with FSE_compress_usingCTable().
+Similar to FSE_count(), the convention is that 'src' is assumed to be a table of char of size 'srcSize'
+The function returns the size of compressed data (without header), necessarily <= `dstCapacity`.
+If it returns '0', compressed data could not fit into 'dst'.
+If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).

+(Note : these functions only decompress FSE-compressed blocks.

+The first step is to obtain the normalized frequencies of symbols.
+This can be performed by FSE_readNCount() if it was saved using FSE_writeNCount().
+'normalizedCounter' must be already allocated, and have at least 'maxSymbolValuePtr[0]+1' cells of signed short.
+In practice, that means it's necessary to know 'maxSymbolValue' beforehand,
+or size the table to handle worst case situations (typically 256).
+FSE_readNCount() will provide 'tableLog' and 'maxSymbolValue'.
+The result of FSE_readNCount() is the number of bytes read from 'rBuffer'.
+Note that 'rBufferSize' must be at least 4 bytes, even if useful information is less than that.
+If there is an error, the function will return an error code, which can be tested using FSE_isError().
+
+The next step is to build the decompression tables 'FSE_DTable' from 'normalizedCounter'.
+This is performed by the function FSE_buildDTable().
+The space required by 'FSE_DTable' must be already allocated using FSE_createDTable().
+If there is an error, the function will return an error code, which can be tested using FSE_isError().
+
+`FSE_DTable` can then be used to decompress `cSrc`, with FSE_decompress_usingDTable().
+`cSrcSize` must be strictly correct, otherwise decompression will fail.
+FSE_decompress_usingDTable() result will tell how many bytes were regenerated (<=`dstCapacity`).

+These functions are inner components of FSE_compress_usingCTable().
+They allow the creation of custom streams, mixing multiple tables and bit sources.
+
+A key property to keep in mind is that encoding and decoding are done **in reverse direction**.
+So the first symbol you will encode is the last you will decode, like a LIFO stack.
+
+You will need a few variables to track your CStream. They are :
+
+FSE_CTable    ct;         // Provided by FSE_buildCTable()
+BIT_CStream_t bitStream;  // bitStream tracking structure
+FSE_CState_t  state;      // State tracking structure (can have several)

+
+The first thing to do is to init bitStream and state.
+    size_t errorCode = BIT_initCStream(&bitStream, dstBuffer, maxDstSize);
+    FSE_initCState(&state, ct);
+
+Note that BIT_initCStream() can produce an error code, so its result should be tested, using FSE_isError();
+You can then encode your input data, byte after byte.
+FSE_encodeSymbol() outputs a maximum of 'tableLog' bits at a time.
+Remember decoding will be done in reverse direction.
+    FSE_encodeByte(&bitStream, &state, symbol);
+
+At any time, you can also add any bit sequence.
+Note : maximum allowed nbBits is 25, for compatibility with 32-bits decoders
+    BIT_addBits(&bitStream, bitField, nbBits);
+
+The above methods don't commit data to memory, they just store it into local register, for speed.
+Local register size is 64-bits on 64-bits systems, 32-bits on 32-bits systems (size_t).
+Writing data to memory is a manual operation, performed by the flushBits function.
+    BIT_flushBits(&bitStream);
+
+Your last FSE encoding operation shall be to flush your last state value(s).
+    FSE_flushState(&bitStream, &state);
+
+Finally, you must close the bitStream.
+The function returns the size of CStream in bytes.
+If data couldn't fit into dstBuffer, it will return a 0 ( == not compressible)
+If there is an error, it returns an errorCode (which can be tested using FSE_isError()).
+    size_t size = BIT_closeCStream(&bitStream);

+and also any other bitFields you put in, **in reverse order**.
+
+You will need a few variables to track your bitStream. They are :

+FSE_DState_t  DState;     // State context. Multiple ones are possible

+(in reverse flushing order if you have several ones) :

+

+Keep in mind that symbols are decoded in reverse order, like a LIFO stack (last in, first out).

+    endSignal = FSE_reloadDStream(&DStream);
+
+BIT_reloadDStream() result tells if there is still some more data to read from DStream.
+BIT_DStream_unfinished : there is still some data left into the DStream.
+BIT_DStream_endOfBuffer : Dstream reached end of buffer. Its container may no longer be completely filled.
+BIT_DStream_completed : Dstream reached its exact end, corresponding in general to decompression completed.
+BIT_DStream_tooFar : Dstream went too far. Decompression result is corrupted.
+
+When reaching end of buffer (BIT_DStream_endOfBuffer), progress slowly, notably if you decode multiple symbols per loop,
+to properly detect the exact end of stream.
+After each decoded symbol, check if DStream is fully consumed using this simple test :
+    BIT_reloadDStream(&DStream) >= BIT_DStream_completed
+
+When it's done, verify decompression is fully completed, by checking both DStream and the relevant states.
+Checking if DStream has reached its end is performed by :
+    BIT_endOfDStream(&DStream);
+Check also the states. There might be some symbols left there, if some high probability ones (>50%) are possible.

+ * Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
+ * The below switch allow to select different access method for improved performance.
+ * Method 0 (default) : use `memcpy()`. Safe and portable.
+ * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
+ *            This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
+ * Method 2 : direct access. This method doesn't depend on compiler but violate C standard.
+ *            It can generate buggy code on targets which do not support unaligned memory accesses.
+ *            But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
+ * See http://stackoverflow.com/a/32095106/646947 for details.

+*  Use ZBUFF_createCCtx() and ZBUFF_freeCCtx() to create/release resources.
+*  ZBUFF_CCtx objects can be reused multiple times.
+*
+*  Start by initializing ZBUF_CCtx.
+*  Use ZBUFF_compressInit() to start a new compression operation.
+*  Use ZBUFF_compressInitDictionary() for a compression which requires a dictionary.
+*
+*  Use ZBUFF_compressContinue() repetitively to consume input stream.
+*  *srcSizePtr and *dstCapacityPtr can be any size.
+*  The function will report how many bytes were read or written within *srcSizePtr and *dstCapacityPtr.
+*  Note that it may not consume the entire input, in which case it's up to the caller to present again remaining data.
+*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each call, so save its content if it matters or change @dst .
+*  @return : a hint to preferred nb of bytes to use as input for next function call (it's just a hint, to improve latency)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  At any moment, it's possible to flush whatever data remains within buffer, using ZBUFF_compressFlush().
+*  The nb of bytes written into `dst` will be reported into *dstCapacityPtr.
+*  Note that the function cannot output more than *dstCapacityPtr,
+*  therefore, some content might still be left into internal buffer if *dstCapacityPtr is too small.
+*  @return : nb of bytes still present into internal buffer (0 if it's empty)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  ZBUFF_compressEnd() instructs to finish a frame.
+*  It will perform a flush and write frame epilogue.
+*  The epilogue is required for decoders to consider a frame completed.
+*  Similar to ZBUFF_compressFlush(), it may not be able to output the entire internal buffer content if *dstCapacityPtr is too small.
+*  In which case, call again ZBUFF_compressFlush() to complete the flush.
+*  @return : nb of bytes still present into internal buffer (0 if it's empty)
+*            or an error code, which can be tested using ZBUFF_isError().
+*
+*  Hint : _recommended buffer_ sizes (not compulsory) : ZBUFF_recommendedCInSize() / ZBUFF_recommendedCOutSize()
+*  input : ZBUFF_recommendedCInSize==128 KB block size is the internal unit, use this value to reduce intermediate stages (better latency)
+*  output : ZBUFF_recommendedCOutSize==ZSTD_compressBound(128 KB) + 3 + 3 : ensures it's always possible to write/flush/end a full block. Skip some buffering.
+*  By using both, it ensures that input will be entirely consumed, and output will always contain the result, reducing intermediate buffering.

+ *  f=20, and accel=1.
+ *  Samples must be stored concatenated in a single flat buffer `samplesBuffer`,
+ *  supplied with an array of sizes `samplesSizes`, providing the size of each sample, in order.
+ *  The resulting dictionary will be saved into `dictBuffer`.
+ * @return: size of dictionary stored into `dictBuffer` (<= `dictBufferCapacity`)
+ *          or an error code, which can be tested with ZDICT_isError().
+ *  Note: ZDICT_trainFromBuffer() requires about 9 bytes of memory for each input byte.
+ *  Tips: In general, a reasonable dictionary has a size of ~ 100 KB.
+ *        It's possible to select smaller or larger size, just by specifying `dictBufferCapacity`.
+ *        In general, it's recommended to provide a few thousands samples, though this can vary a lot.
+ *        It's recommended that total size of all samples be about ~x100 times the target size of dictionary.

+/*******************************************************************************
+  Introduction
+
+  zstd, short for Zstandard, is a fast lossless compression algorithm, targeting
+  real-time compression scenarios at zlib-level and better compression ratios.
+  The zstd compression library provides in-memory compression and decompression
+  functions.
+
+  The library supports regular compression levels from 1 up to ZSTD_maxCLevel(),
+  which is currently 22. Levels >= 20, labeled `--ultra`, should be used with
+  caution, as they require more memory. The library also offers negative
+  compression levels, which extend the range of speed vs. ratio preferences.
+  The lower the level, the faster the speed (at the cost of compression).
+
+  Compression can be done in:
+    - a single step (described as Simple API)
+    - a single step, reusing a context (described as Explicit context)
+    - unbounded multiple steps (described as Streaming compression)
+
+  The compression ratio achievable on small data can be highly improved using
+  a dictionary. Dictionary compression can be performed in:
+    - a single step (described as Simple dictionary API)
+    - a single step, reusing a dictionary (described as Bulk-processing
+      dictionary API)
+
+  Advanced experimental functions can be accessed using
+  `#define ZSTD_STATIC_LINKING_ONLY` before including zstd.h.
+
+  Advanced experimental APIs should never be used with a dynamically-linked
+  library. They are not "stable"; their definitions or signatures may change in
+  the future. Only static linking is allowed.

+*  Streaming compression - HowTo
+*
+*  A ZSTD_CStream object is required to track streaming operation.
+*  Use ZSTD_createCStream() and ZSTD_freeCStream() to create/release resources.
+*  ZSTD_CStream objects can be reused multiple times on consecutive compression operations.
+*  It is recommended to re-use ZSTD_CStream since it will play nicer with system's memory, by re-using already allocated memory.
+*
+*  For parallel execution, use one separate ZSTD_CStream per thread.
+*
+*  note : since v1.3.0, ZSTD_CStream and ZSTD_CCtx are the same thing.
+*
+*  Parameters are sticky : when starting a new compression on the same context,
+*  it will re-use the same sticky parameters as previous compression session.
+*  When in doubt, it's recommended to fully initialize the context before usage.
+*  Use ZSTD_initCStream() to set the parameter to a selected compression level.
+*  Use advanced API (ZSTD_CCtx_setParameter(), etc.) to set more specific parameters.
+*
+*  Use ZSTD_compressStream() as many times as necessary to consume input stream.
+*  The function will automatically update both `pos` fields within `input` and `output`.
+*  Note that the function may not consume the entire input,
+*  for example, because the output buffer is already full,
+*  in which case `input.pos < input.size`.
+*  The caller must check if input has been entirely consumed.
+*  If not, the caller must make some room to receive more compressed data,
+*  and then present again remaining input data.
+* @return : a size hint, preferred nb of bytes to use as input for next function call
+*           or an error code, which can be tested using ZSTD_isError().
+*           Note 1 : it's just a hint, to help latency a little, any value will work fine.
+*           Note 2 : size hint is guaranteed to be <= ZSTD_CStreamInSize()
+*
+*  At any moment, it's possible to flush whatever data might remain stuck within internal buffer,
+*  using ZSTD_flushStream(). `output->pos` will be updated.
+*  Note that, if `output->size` is too small, a single invocation of ZSTD_flushStream() might not be enough (return code > 0).
+*  In which case, make some room to receive more compressed data, and call again ZSTD_flushStream().
+*  @return : 0 if internal buffers are entirely flushed,
+*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
+*            or an error code, which can be tested using ZSTD_isError().
+*
+*  ZSTD_endStream() instructs to finish a frame.
+*  It will perform a flush and write frame epilogue.
+*  The epilogue is required for decoders to consider a frame completed.
+*  flush() operation is the same, and follows same rules as ZSTD_flushStream().
+*  @return : 0 if frame fully completed and fully flushed,
+*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),

+  Buffer-less streaming decompression (synchronous mode)

+  A ZSTD_DCtx object can be re-used multiple times.
+
+  First typical operation is to retrieve frame parameters, using ZSTD_getFrameHeader().
+  Frame header is extracted from the beginning of compressed frame, so providing only the frame's beginning is enough.
+  Data fragment must be large enough to ensure successful decoding.
+ `ZSTD_frameHeaderSize_max` bytes is guaranteed to always be large enough.
+  @result : 0 : successful decoding, the `ZSTD_frameHeader` structure is correctly filled.
+           >0 : `srcSize` is too small, please provide at least @result bytes on next attempt.
+           errorCode, which can be tested using ZSTD_isError().
+
+  It fills a ZSTD_frameHeader structure with important information to correctly decode the frame,
+  such as the dictionary ID, content size, or maximum back-reference distance (`windowSize`).
+  Note that these values could be wrong, either because of data corruption, or because a 3rd party deliberately spoofs false information.
+  As a consequence, check that values remain within valid application range.
+  For example, do not allocate memory blindly, check that `windowSize` is within expectation.
+  Each application can set its own limits, depending on local restrictions.
+  For extended interoperability, it is recommended to support `windowSize` of at least 8 MB.
+
+  ZSTD_decompressContinue() needs previous data blocks during decompression, up to `windowSize` bytes.
+  ZSTD_decompressContinue() is very sensitive to contiguity,
+  if 2 blocks don't follow each other, make sure that either the compressor breaks contiguity at the same place,
+  or that previous contiguous segment is large enough to properly handle maximum back-reference distance.
+  There are multiple ways to guarantee this condition.
+
+  The most memory efficient way is to use a round buffer of sufficient size.
+  Sufficient size is determined by invoking ZSTD_decodingBufferSize_min(),
+  which can @return an error code if required value is too large for current system (in 32-bits mode).
+  In a round buffer methodology, ZSTD_decompressContinue() decompresses each block next to previous one,
+  up to the moment there is not enough room left in the buffer to guarantee decoding another full block,
+  which maximum size is provided in `ZSTD_frameHeader` structure, field `blockSizeMax`.
+  At which point, decoding can resume from the beginning of the buffer.
+  Note that already decoded data stored in the buffer should be flushed before being overwritten.
+
+  There are alternatives possible, for example using two or more buffers of size `windowSize` each, though they consume more memory.
+
+  Finally, if you control the compression process, you can also ignore all buffer size rules,
+  as long as the encoder and decoder progress in "lock-step",
+  aka use exactly the same buffer sizes, break contiguity at the same place, etc.
+
+  Once buffers are setup, start decompression, with ZSTD_decompressBegin().
+  If decompression requires a dictionary, use ZSTD_decompressBegin_usingDict() or ZSTD_decompressBegin_usingDDict().
+
+  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
+  ZSTD_nextSrcSizeToDecompress() tells how many bytes to provide as 'srcSize' to ZSTD_decompressContinue().
+  ZSTD_decompressContinue() requires this _exact_ amount of bytes, or it will fail.
+
+ @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity).
+  It can be zero : it just means ZSTD_decompressContinue() has decoded some metadata item.
+  It can also be an error code, which can be tested with ZSTD_isError().
+
+  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
+  Context can then be reset to start a new decompression.
+
+  Note : it's possible to know if next input to present is a header or a block, using ZSTD_nextInputType().
+  This information is not required to properly decode a frame.
+
+  == Special case : skippable frames ==
+
+  Skippable frames allow integration of user-defined data into a flow of concatenated frames.
+  Skippable frames will be ignored (skipped) by decompressor.
+  The format of skippable frames is as follows :
+  a) Skippable frame ID - 4 Bytes, Little endian format, any value from 0x184D2A50 to 0x184D2A5F
+  b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
+  c) Frame Content - any content (User Data) of length equal to Frame Size
+  For skippable frames ZSTD_getFrameHeader() returns zfhPtr->frameType==ZSTD_skippableFrame.
+  For skippable frames ZSTD_decompressContinue() always returns 0 : it only skips the content.

+    Block functions produce and decode raw zstd blocks, without frame metadata.
+    Frame metadata cost is typically ~18 bytes, which can be non-negligible for very small blocks (< 100 bytes).
+    User will have to take in charge required information to regenerate data, such as compressed and content sizes.
+
+    A few rules to respect :
+    - Compressing and decompressing require a context structure
+      + Use ZSTD_createCCtx() and ZSTD_createDCtx()
+    - It is necessary to init context before starting
+      + compression : any ZSTD_compressBegin*() variant, including with dictionary
+      + decompression : any ZSTD_decompressBegin*() variant, including with dictionary
+      + copyCCtx() and copyDCtx() can be used too
+    - Block size is limited, it must be <= ZSTD_getBlockSize() <= ZSTD_BLOCKSIZE_MAX == 128 KB
+      + If input is larger than a block size, it's necessary to split input data into multiple blocks
+      + For inputs larger than a single block, really consider using regular ZSTD_compress() instead.
+        Frame metadata is not that costly, and quickly becomes negligible as source size grows larger.
+    - When a block is considered not compressible enough, ZSTD_compressBlock() result will be zero.
+      In which case, nothing is produced into `dst` !
+      + User must test for such outcome and deal directly with uncompressed data
+      + ZSTD_decompressBlock() doesn't accept uncompressed data as input !!!
+      + In case of multiple successive blocks, should some of them be uncompressed,
+        decoder must be informed of their existence in order to follow proper history.
+        Use ZSTD_insertBlock() for such a case.
