+
+Filesystem path manipulation command.
+
+This command is dedicated to the manipulation of objects of type path which
+represent paths on a filesystem. Only syntactic aspects of paths are handled:
+the pathname may represent a non-existing path or even one that is not allowed
+to exist on the current file system or OS.
+
+For operations involving the filesystem, have a look at the :command:`file`
+command.
+
+The path name has the following syntax:
+
+1. ``root-name`` (optional): identifies the root on a filesystem with multiple
+   roots (such as ``"C:"`` or ``"//myserver"``).
+
+2. ``root-directory`` (optional): a directory separator that, if present, marks
+   this path as absolute. If it is missing (and the first element other than
+   the ``root-name`` is a ``item-name``), then the path is relative.
+
+Zero or more of the following:
+
+3. ``item-name``: sequence of characters that aren't directory separators. This
+   name may identify a file, a hard link, a symbolic link, or a directory. Two
+   special ``item-names`` are recognized:
+
+     * ``dot``: the item name consisting of a single dot character ``.`` is a
+       directory name that refers to the current directory.
+
+     * ``dot-dot``: the item name consisting of two dot characters ``..`` is a
+       directory name that refers to the parent directory.
+
+4. ``directory-separator``: the forward slash character ``/``. If this
+   character is repeated, it is treated as a single directory separator:
+   ``/usr///////lib`` is the same as ``/usr/lib``.
+
+.. _FILENAME_DEF:
+
+A path has a filename if it does not ends with a ``directory-separator``. The
+filename is the last ``item-name`` of the path.
+
+.. _EXTENSION_DEF:
+
+A :ref:`filename <FILENAME_DEF>` can have an extension. By default, the
+extension is defined as the sub-string beginning at the leftmost period
+(including the period) and until the end of the pathname. When the option
+``LAST_ONLY`` is specified, the extension is the sub-string beginning at the
+rightmost period.
+
+The following exceptions apply:
+
+  * If the first character in the :ref:`filename <FILENAME_DEF>` is a period,
+    that period is ignored (a filename like ``".profile"`` is not treated as an
+    extension).
+
+  * If the pathname is either ``.`` or ``..``.
+
+.. note::
+
+  ``cmake_path`` command handles paths in the format of the build system, not
+  the target system. So this is not generally applicable to the target system
+  in cross-compiling environment.
+
+For all commands, ``<path-var>`` placeholder expect a variable name. An error
+will be raised if the variable does not exist, except for `SET`_ and `APPEND`_
+sub-commands. ``<input>`` placeholder expect a string literal.
+``[<input>...]`` placeholder expect zero or more arguments. ``<out-var>``
+placeholder expect a variable name.
+
+.. note::
+
+  ``cmake_path`` command does not support list of paths. The ``<path-var>``
+  placeholder must store only one path name.
+
+To initialize a path variable, three possibilities can be used:
+
+1. :command:`set` command.
+2. :ref:`cmake_path(SET) <SET>` command. Mainly used to build a
+   path variable from a native path.
+3. :ref:`cmake_path(APPEND) <APPEND>` command. Can be used to build a path from
+   already available path fragments.
+
+  .. code-block:: cmake
+
+    # To build the path "${CMAKE_CURRENT_SOURCE_DIR}/data"
+
+    set (path1 "${CMAKE_CURRENT_SOURCE_DIR}/data")
+
+    cmake_path(SET path2 "${CMAKE_CURRENT_SOURCE_DIR}/data")
+
+    cmake_path(APPEND path3 "${CMAKE_CURRENT_SOURCE_DIR}" "data")
+
+`Modification`_ and `Generation`_ sub-commands store the result in-place or in
+the variable specified by  ``OUTPUT_VARIABLE`` option. All other sub-commands

+Decomposition
+^^^^^^^^^^^^^
+
+.. _GET:
+.. _GET_ROOT_NAME:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> ROOT_NAME <out-var>)
+
+Returns the root name of the path. If the path does not include a root name,
+returns an empty path.
+
+.. note::
+
+  Only ``Windows`` system has the concept of ``root-name``, so on all other
+  systems, it is always an empty path.
+
+For example:
+
+  .. code-block:: cmake
+
+    set (path "c:/a")
+    cmake_path (GET path ROOT_NAME output)
+    message ("Root name is \"${output}\"")
+
+  Will display::
+
+    Root name is "c:"
+
+.. _GET_ROOT_DIRECTORY:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> ROOT_DIRECTORY <out-var>)
+
+Returns the root directory of the path. If the path does not include a root
+directory, returns an empty path.
+
+For example:
+
+  .. code-block:: cmake
+
+    set (path "c:/a")
+    cmake_path (GET path ROOT_DIRECTORY output)
+    message ("Root directory is \"${output}\"")
+
+  Will display::
+
+    Root directory is "/"
+
+.. _GET_ROOT_PATH:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> ROOT_PATH <out-var>)
+
+Returns the root path of the path. If the path does not include a root path,
+returns an empty path.
+
+Effectively, returns the following: ``root-name root-directory``.
+
+For example:
+
+  .. code-block:: cmake
+
+    set (path "c:/a")
+    cmake_path (GET path ROOT_PATH output)
+    message ("Root path is \"${output}\"")
+
+  Will display::
+
+    Root path is "c:/"
+
+.. _GET_FILENAME:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> FILENAME <out-var>)
+
+Returns the :ref:`filename <FILENAME_DEF>` component of the path. If the path
+ends with a ``directory-separator``, there is no filename, so returns an empty
+path.
+
+For example:
+
+  .. code-block:: cmake
+
+    set (path "/a")
+    cmake_path (GET path FILENAME output)
+    message ("First filename is \"${output}\"")
+
+    set (path "/a/")
+    cmake_path (GET path FILENAME output)
+    message ("Second filename is \"${output}\"")
+
+  Will display::
+
+    First filename is "a"
+    Second filename is ""
+
+.. _GET_EXTENSION:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> EXTENSION [LAST_ONLY] <out-var>)
+
+Returns the :ref:`extension <EXTENSION_DEF>` of the filename component.
+
+If the :ref:`filename <FILENAME_DEF>` component of the path contains a period
+(``.``), and is not one of the special filesystem elements ``dot`` or
+``dot-dot``, then the :ref:`extension <EXTENSION_DEF>` is returned.
+
+For example:
+
+  .. code-block:: cmake
+
+    set (path "name.ext1.ext2")
+    cmake_path (GET path EXTENSION result)
+    message ("Full extension is \"${result}\"")
+    cmake_path (GET path EXTENSION LAST_ONLY result)
+    message ("Last extension is \"${result}\"")
+
+  Will display::
+
+    Full extension is ".ext1.ext2"
+    Last extension is ".ext2"
+
+The following exceptions apply:
+
+  * If the first character in the filename is a period, that period is ignored
+    (a filename like ``".profile"`` is not treated as an extension).
+
+  * If the pathname is either ``.`` or ``..``, or if
+    :ref:`filename <FILENAME_DEF>` component does not contain the ``.``
+    character, then an empty path is returned.
+
+.. _GET_STEM:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> STEM [LAST_ONLY] <out-var>)
+
+Returns the :ref:`filename <FILENAME_DEF>` component of the path stripped of
+its :ref:`extension <EXTENSION_DEF>`.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (path "name.ext1.ext2")
+    cmake_path (GET path STEM result)
+    message ("Filename without the extension is \"${result}\"")
+    cmake_path (GET path STEM LAST_ONLY result)
+    message ("Filename whiteout the last extension is \"${result}\"")
+
+  Will display::
+
+    Filename without the extension is "name"
+    Filename without the last extension is "name.ext1"
+
+The following exceptions apply:
+
+  * If the first character in the filename is a period, that period is ignored
+    (a filename like ``".profile"`` is not treated as an extension).
+
+  * If the filename is one of the special filesystem components ``dot`` or
+    ``dot-dot``, or if it has no periods, the function returns the entire
+    :ref:`filename <FILENAME_DEF>` component.
+
+.. _GET_RELATIVE_PATH:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> RELATIVE_PATH <out-var>)
+
+Returns path relative to ``root-path``, that is, a pathname composed of
+every component of ``<path-var>`` after ``root-path``. If ``<path-var>`` is
+an empty path, returns an empty path.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (path "/a/b")
+    cmake_path (GET path RELATIVE_PATH result)
+    message ("Relative path is \"${result}\"")
+
+    set (path "/")
+    cmake_path (GET path RELATIVE_PATH result)
+    message ("Relative path is \"${result}\"")
+
+  Will display::
+
+    Relative path is "a/b"
+    Relative path is ""
+
+.. _GET_PARENT_PATH:
+
+.. code-block:: cmake
+
+  cmake_path(GET <path-var> PARENT_PATH <out-var>)
+
+Returns the path to the parent directory.
+
+If `HAS_RELATIVE_PATH`_ sub-command returns false, the result is a copy of
+``<path-var>``. Otherwise, the result is ``<path-var>`` with one fewer element.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (path "c:/a/b")
+    cmake_path (GET path PARENT_PATH result)
+    message ("Parent path is \"${result}\"")
+
+    set (path "c:/")
+    cmake_path (GET path PARENT_PATH result)
+    message ("Parent path is \"${result}\"")
+
+  Will display::
+
+    Parent path is "c:/a"
+    Relative path is "c:/"
+
+Modification
+^^^^^^^^^^^^
+
+.. _cmake_path-SET:
+.. _SET:
+
+.. code-block:: cmake
+
+    cmake_path(SET <path-var> [NORMALIZE] <input>)
+
+Assign the ``<input>`` path to ``<path-var>``. Moreover, if ``<input>`` is a
+native path, it is converted into cmake-style path with forward-slashes
+(``/``). On Windows, the long filename marker is taken into account.
+
+When ``NORMALIZE`` option is specified, the path is :ref:`normalized
+<NORMAL_PATH>` before the conversion.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (native_path "c:\\a\\b/..\\c")
+    cmake_path (SET path "${native_path}")
+    message ("CMake path is \"${path}\"")
+
+    cmake_path (SET path NORMALIZE "${native_path}")
+    message ("Normalized CMake path is \"${path}\"")
+
+  Will display::
+
+    CMake path is "c:/a/b/../c"
+    Normalized CMake path is "c:/a/c"
+
+.. _APPEND:
+
+.. code-block:: cmake
+
+    cmake_path(APPEND <path-var> [<input>...] [OUTPUT_VARIABLE <out-var>])
+
+Append all the ``<input>`` arguments to the ``<path-var>`` using ``/`` as
+``directory-separator``.
+
+For each ``<input>`` argument, the following algorithm (pseudo-code) applies:
+
+  .. code-block:: cmake
+
+    # <path> is the contents of <path-var>
+
+    IF (<input>.is_absolute() OR
+         (<input>.has_root_name() AND
+          NOT <input>.root_name() STREQUAL <path>.root_name()))
+      replaces <path> with <input>
+      RETURN()
+    ENDIF()
+
+    IF (<input>.has_root_directory())
+      remove any root-directory and the entire relative path from <path>
+    ELSEIF (<path>.has_filename() OR
+             (NOT <path-var>.has_root_directory() OR <path>.is_absolute()))
+      appends directory-separator to <path>
+    ENDIF()
+
+    appends <input> omitting any root-name to <path>
+
+.. _APPEND_STRING:
+
+.. code-block:: cmake
+
+    cmake_path(APPEND_STRING <path-var> [<input>...] [OUTPUT_VARIABLE <out-var>])
+
+Append all the ``<input>`` arguments to the ``<path-var>`` without
+``directory-separator``.
+
+.. _REMOVE_FILENAME:
+
+.. code-block:: cmake
+
+    cmake_path(REMOVE_FILENAME <path-var> [OUTPUT_VARIABLE <out-var>])
+
+Removes the :ref:`filename <FILENAME_DEF>` component (as returned by
+:ref:`GET ... FILENAME <GET_FILENAME>`) from ``<path-var>``.
+
+After this function returns, if change is done in-place, `HAS_FILENAME`_
+returns false for ``<path-var>``.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (path "/a/b")
+    cmake_path (REMOVE_FILENAME path)
+    message ("First path is \"${path}\"")
+
+    cmake_path (REMOVE_FILENAME path)
+    message ("Second path is \"${result}\"")
+
+  Will display::
+
+    First path is "/a/"
+    Second path is "/a/"
+
+.. _REPLACE_FILENAME:
+
+.. code-block:: cmake
+
+    cmake_path(REPLACE_FILENAME <path-var> <input> [OUTPUT_VARIABLE <out-var>])
+
+Replaces the :ref:`filename <FILENAME_DEF>` component from ``<path-var>`` with
+``<input>``.
+
+If ``<path-var>`` has no filename component (`HAS_FILENAME`_ returns false),
+the path is unchanged.
+
+Equivalent to the following:
+
+  .. code-block:: cmake
+
+    cmake_path(HAS_FILENAME path has_filename)
+    if (has_filename)
+      cmake_path(REMOVE_FILENAME path)
+      cmake_path(APPEND path "replacement");
+    endif()
+
+.. _REMOVE_EXTENSION:
+
+.. code-block:: cmake
+
+    cmake_path(REMOVE_EXTENSION <path-var> [LAST_ONLY]
+                                           [OUTPUT_VARIABLE <out-var>])
+
+Removes the :ref:`extension <EXTENSION_DEF>`, if any, from ``<path-var>``.
+
+.. _REPLACE_EXTENSION:
+
+.. code-block:: cmake
+
+    cmake_path(REPLACE_EXTENSION <path-var> [LAST_ONLY] <input>
+                                 [OUTPUT_VARIABLE <out-var>])
+
+Replaces the :ref:`extension <EXTENSION_DEF>` with ``<input>``.
+
+  1. If ``<path-var>`` has an :ref:`extension <EXTENSION_DEF>`
+     (`HAS_EXTENSION`_ is true), it is removed.
+  2. A ``dot`` character is appended to ``<path-var>``, if ``<input>`` is not
+     empty or does not begin with a ``dot`` character.
+  3. ``<input>`` is appended as if `APPEND_STRING`_ was used.
+
+
+Equivalent to the following:
+
+  .. code-block:: cmake
+
+    cmake_path(REMOVE_EXTENSION path)
+    if (NOT "input" MATCHES "^\\.")
+      cmake_path(APPEND_STRING path ".")
+    endif()
+    cmake_path(APPEND_STRING path "input");
+
+Generation
+^^^^^^^^^^
+
+.. _NORMAL_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(NORMAL_PATH <path-var> [OUTPUT_VARIABLE <out-var>])
+
+Normalize ``<path-var>``.
+
+A path can be normalized by following this algorithm:
+
+  1. If the path is empty, stop (normal form of an empty path is an empty
+     path).
+  2. Replace each ``directory-separator`` (which may consist of multiple
+     separators) with a single ``/``.
+  3. Replace each ``directory-separator`` character in the ``root-name`` with
+     ``/``.
+  4. Remove each ``dot`` and any immediately following ``directory-separator``.
+  5. Remove each non-dot-dot filename immediately followed by a
+     ``directory-separator`` and a ``dot-dot``, along with any immediately
+     following ``directory-separator``.
+  6. If there is ``root-directory``, remove all ``dot-dots`` and any
+     ``directory-separators`` immediately following them.
+  7. If the last filename is ``dot-dot``, remove any trailing
+     ``directory-separator``.
+  8. If the path is empty, add a ``dot`` (normal form of ``./`` is ``.``).
+
+.. _cmake_path-RELATIVE_PATH:
+.. _RELATIVE_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(RELATIVE_PATH <path-var> [BASE_DIRECTORY <input>]
+                                        [OUTPUT_VARIABLE <out-var>])
+
+Returns ``<path-var>`` made relative to ``BASE_DIRECTORY`` argument. If
+``BASE_DIRECTORY`` is not specified, the default base directory will be
+:variable:`CMAKE_CURRENT_SOURCE_DIR`.
+
+For reference, the algorithm used to compute the relative path is described
+`here <https://en.cppreference.com/w/cpp/filesystem/path/lexically_normal>`_.
+
+.. _ABSOLUTE_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(ABSOLUTE_PATH <path-var> [BASE_DIRECTORY <input>] [NORMALIZE]
+                                        [OUTPUT_VARIABLE <out-var>])
+
+If ``<path-var>`` is a relative path (`IS_RELATIVE`_ is true), it is evaluated
+relative to the given base directory specified by ``BASE_DIRECTORY`` option.
+
+If ``BASE_DIRECTORY`` is not specifired, the default base directory will be
+:variable:`CMAKE_CURRENT_SOURCE_DIR`.
+
+When ``NORMALIZE`` option is specified, the path is :ref:`normalized
+<NORMAL_PATH>` after the path computation.
+
+Because ``cmake_path`` does not access to the filesystem, symbolic links are
+not resolved. To compute a real path, use :command:`file(REAL_PATH)`
+command.
+
+Conversion
+^^^^^^^^^^
+
+.. _cmake_path-NATIVE_PATH:
+.. _NATIVE_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(NATIVE_PATH <path-var> [NORMALIZE] <out-var>)
+
+Converts a cmake-style ``<path-var>`` into a native
+path with platform-specific slashes (``\`` on Windows and ``/`` elsewhere).
+
+When ``NORMALIZE`` option is specified, the path is :ref:`normalized
+<NORMAL_PATH>` before the conversion.
+
+.. _CONVERT:
+.. _cmake_path-TO_CMAKE_PATH_LIST:
+.. _TO_CMAKE_PATH_LIST:
+
+.. code-block:: cmake
+
+   cmake_path(CONVERT <input> TO_CMAKE_PATH_LIST <out-var> [NORMALIZE])
+
+Converts a native ``<input>`` path into cmake-style path with forward-slashes
+(``/``).  On Windows, the long filename marker is taken into account. The input
+can be a single path or a system search path like ``$ENV{PATH}``.  A search
+path will be converted to a cmake-style list separated by ``;`` characters. The
+result of the conversion is stored in the ``<out-var>`` variable.
+
+When ``NORMALIZE`` option is specified, the path is :ref:`normalized
+<NORMAL_PATH>` before the conversion.
+
+.. _cmake_path-TO_NATIVE_PATH_LIST:
+.. _TO_NATIVE_PATH_LIST:
+
+.. code-block:: cmake
+
+  cmake_path(CONVERT <input> TO_NATIVE_PATH_LIST <out-var> [NORMALIZE])
+
+Converts a cmake-style ``<input>`` path into a native path with
+platform-specific slashes (``\`` on Windows and ``/`` elsewhere). The input can
+be a single path or a cmake-style list. A list will be converted into a native
+search path. The result of the conversion is stored in the ``<out-var>``
+variable.
+
+When ``NORMALIZE`` option is specified, the path is :ref:`normalized
+<NORMAL_PATH>` before the conversion.
+
+For Example:
+
+  .. code-block:: cmake
+
+    set (paths "/a/b/c" "/x/y/z")
+    cmake_path (CONVERT "${paths}" TO_NATIVE_PATH_LIST native_paths)
+    message ("Native path list is \"${native_paths}\"")
+
+  Will display, on Windows::
+
+    Native path list is "\a\b\c;\x\y\z"
+
+  And on the all other systems::
+
+    Native path list is "/a/b/c:/x/y/z"
+
+Comparison
+^^^^^^^^^^
+
+.. _COMPARE:
+
+.. code-block:: cmake
+
+    cmake_path(COMPARE <input1> EQUAL <input2> <out-var>)
+    cmake_path(COMPARE <input1> NOT_EQUAL <input2> <out-var>)
+
+Compares the lexical representations of the path and another path.
+
+For testing equality, the following algorithm (pseudo-code) apply:
+
+  .. code-block:: cmake
+
+    IF (NOT <input1>.root_name() STREQUAL <input2>.root_name())
+      returns FALSE
+    ELSEIF (<input1>.has_root_directory() XOR <input2>.has_root_directory())
+      returns FALSE
+    ENDIF()
+
+    returns TRUE or FALSE if the relative portion of <input1> is
+      lexicographically equal or not to the relative portion of <input2>.
+      Comparison is performed path component-wise
+
+Query
+^^^^^
+
+.. _HAS_ROOT_NAME:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_ROOT_NAME <path-var> <out-var>)
+
+Checks if ``<path-var>`` has ``root-name``.
+
+.. _HAS_ROOT_DIRECTORY:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_ROOT_DIRECTORY <path-var> <out-var>)
+
+Checks if ``<path-var>`` has ``root-directory``.
+
+.. _HAS_ROOT_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_ROOT_PATH <path-var> <out-var>)
+
+Checks if ``<path-var>`` has root path.
+
+Effectively, checks if ``<path-var>`` has ``root-name`` and ``root-directory``.
+
+.. _HAS_FILENAME:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_FILENAME <path-var> <out-var>)
+
+Checks if ``<path-var>`` has a :ref:`filename <FILENAME_DEF>`.
+
+.. _HAS_EXTENSION:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_EXTENSION <path-var> <out-var>)
+
+Checks if ``<path-var>`` has an :ref:`extension <EXTENSION_DEF>`. If the first
+character in the filename is a period, it is not treated as an extension (for
+example ".profile").
+
+.. _HAS_STEM:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_STEM <path-var> <out-var>)
+
+Checks if ``<path-var>`` has stem (:ref:`GET ... STEM <GET_STEM>` returns a non

+
+.. _HAS_RELATIVE_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_RELATIVE_PATH <path-var> <out-var>)
+
+Checks if ``<path-var>`` has relative path (`GET_RELATIVE_PATH`_ returns a

+
+.. _HAS_PARENT_PATH:
+
+.. code-block:: cmake
+
+    cmake_path(HAS_PARENT_PATH <path-var> <out-var>)
+
+Checks if ``<path-var>`` has parent path. The result is true except if the path
+is only composed of a :ref:`filename <FILENAME_DEF>`.
+
+.. _IS_ABSOLUTE:
+
+.. code-block:: cmake
+
+    cmake_path(IS_ABSOLUTE <path-var> <out-var>)
+
+Checks if ``<path-var>`` is absolute.
+
+An absolute path is a path that unambiguously identifies the location of a file

-:manual:`cmake(1)` is capable of providing semantic information about
-CMake code it executes to generate a buildsystem.  If executed with
-the ``-E server`` command line options, it starts in a long running mode
-and allows a client to request the available information via a JSON protocol.
-
-The protocol is designed to be useful to IDEs, refactoring tools, and
-other tools which have a need to understand the buildsystem in entirety.
-
-A single :manual:`cmake-buildsystem(7)` may describe buildsystem contents
-and build properties which differ based on
-:manual:`generation-time context <cmake-generator-expressions(7)>`
-including:
-
-* The Platform (eg, Windows, APPLE, Linux).
-* The build configuration (eg, Debug, Release, Coverage).
-* The Compiler (eg, MSVC, GCC, Clang) and compiler version.
-* The language of the source files compiled.
-* Available compile features (eg CXX variadic templates).
-* CMake policies.
-
-The protocol aims to provide information to tooling to satisfy several
-needs:
-
-#. Provide a complete and easily parsed source of all information relevant
-   to the tooling as it relates to the source code.  There should be no need
-   for tooling to parse generated buildsystems to access include directories
-   or compile definitions for example.
-#. Semantic information about the CMake buildsystem itself.
-#. Provide a stable interface for reading the information in the CMake cache.
-#. Information for determining when cmake needs to be re-run as a result of
-   file changes.
-
-
-Operation
-=========
-
-Start :manual:`cmake(1)` in the server command mode, supplying the path to
-the build directory to process::
-
-  cmake -E server (--debug|--pipe=<NAMED_PIPE>)
-
-The server will communicate using stdin/stdout (with the ``--debug`` parameter)
-or using a named pipe (with the ``--pipe=<NAMED_PIPE>`` parameter).  Note
-that "named pipe" refers to a local domain socket on Unix and to a named pipe
-on Windows.
-
-When connecting to the server (via named pipe or by starting it in ``--debug``
-mode), the server will reply with a hello message::
-
-  [== "CMake Server" ==[
-  {"supportedProtocolVersions":[{"major":1,"minor":0}],"type":"hello"}
-  ]== "CMake Server" ==]
-
-Messages sent to and from the process are wrapped in magic strings::
-
-  [== "CMake Server" ==[
-  {
-    ... some JSON message ...
-  }
-  ]== "CMake Server" ==]
-
-The server is now ready to accept further requests via the named pipe
-or stdin.
-
-
-Debugging
-=========
-
-CMake server mode can be asked to provide statistics on execution times, etc.
-or to dump a copy of the response into a file. This is done passing a "debug"
-JSON object as a child of the request.
-
-The debug object supports the "showStats" key, which takes a boolean and makes
-the server mode return a "zzzDebug" object with stats as part of its response.
-"dumpToFile" takes a string value and will cause the cmake server to copy
-the response into the given filename.
-
-This is a response from the cmake server with "showStats" set to true::
-
-  [== "CMake Server" ==[
-  {
-    "cookie":"",
-    "errorMessage":"Waiting for type \"handshake\".",
-    "inReplyTo":"unknown",
-   "type":"error",
-    "zzzDebug": {
-      "dumpFile":"/tmp/error.txt",
-      "jsonSerialization":0.011016,
-      "size":111,
-      "totalTime":0.025995
-    }
-  }
-  ]== "CMake Server" ==]
-
-The server has made a copy of this response into the file /tmp/error.txt and
-took 0.011 seconds to turn the JSON response into a string, and it took 0.025
-seconds to process the request in total. The reply has a size of 111 bytes.
-
-
-Protocol API
-============
-
-
-General Message Layout
-----------------------
-
-All messages need to have a "type" value, which identifies the type of
-message that is passed back or forth. E.g. the initial message sent by the
-server is of type "hello". Messages without a type will generate an response
-of type "error".
-
-All requests sent to the server may contain a "cookie" value. This value
-will he handed back unchanged in all responses triggered by the request.
-
-All responses will contain a value "inReplyTo", which may be empty in
-case of parse errors, but will contain the type of the request message
-in all other cases.
-
-
-Type "reply"
-^^^^^^^^^^^^
-
-This type is used by the server to reply to requests.
-
-The message may -- depending on the type of the original request --
-contain values.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"cookie":"zimtstern","inReplyTo":"handshake","type":"reply"}
-  ]== "CMake Server" ==]
-
-
-Type "error"
-^^^^^^^^^^^^
-
-This type is used to return an error condition to the client. It will
-contain an "errorMessage".
-
-Example::
-
-  [== "CMake Server" ==[
-  {"cookie":"","errorMessage":"Protocol version not supported.","inReplyTo":"handshake","type":"error"}
-  ]== "CMake Server" ==]
-
-
-Type "progress"
-^^^^^^^^^^^^^^^
-
-When the server is busy for a long time, it is polite to send back replies of
-type "progress" to the client. These will contain a "progressMessage" with a
-string describing the action currently taking place as well as
-"progressMinimum", "progressMaximum" and "progressCurrent" with integer values
-describing the range of progress.
-
-Messages of type "progress" will be followed by more "progress" messages or with
-a message of type "reply" or "error" that complete the request.
-
-"progress" messages may not be emitted after the "reply" or "error" message for
-the request that triggered the responses was delivered.
-
-
-Type "message"
-^^^^^^^^^^^^^^
-
-A message is triggered when the server processes a request and produces some
-form of output that should be displayed to the user. A Message has a "message"
-with the actual text to display as well as a "title" with a suggested dialog
-box title.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"cookie":"","message":"Something happened.","title":"Title Text","inReplyTo":"handshake","type":"message"}
-  ]== "CMake Server" ==]
-
-
-Type "signal"
-^^^^^^^^^^^^^
-
-The server can send signals when it detects changes in the system state. Signals
-are of type "signal", have an empty "cookie" and "inReplyTo" field and always
-have a "name" set to show which signal was sent.
-
-
-Specific Signals
-----------------
-
-The cmake server may sent signals with the following names:
-
-"dirty" Signal
-^^^^^^^^^^^^^^
-
-The "dirty" signal is sent whenever the server determines that the configuration
-of the project is no longer up-to-date. This happens when any of the files that have
-an influence on the build system is changed.
-
-The "dirty" signal may look like this::
-
-  [== "CMake Server" ==[
-  {
-    "cookie":"",
-    "inReplyTo":"",
-    "name":"dirty",
-    "type":"signal"}
-  ]== "CMake Server" ==]
-
-
-"fileChange" Signal
-^^^^^^^^^^^^^^^^^^^
-
-The "fileChange" signal is sent whenever a watched file is changed. It contains
-the "path" that has changed and a list of "properties" with the kind of change
-that was detected. Possible changes are "change" and "rename".
-
-The "fileChange" signal looks like this::
-
-  [== "CMake Server" ==[
-  {
-    "cookie":"",
-    "inReplyTo":"",
-    "name":"fileChange",
-    "path":"/absolute/CMakeLists.txt",
-    "properties":["change"],
-    "type":"signal"}
-  ]== "CMake Server" ==]
-
-
-Specific Message Types
-----------------------
-
-
-Type "hello"
-^^^^^^^^^^^^
-
-The initial message send by the cmake server on startup is of type "hello".
-This is the only message ever sent by the server that is not of type "reply",
-"progress" or "error".
-
-It will contain "supportedProtocolVersions" with an array of server protocol
-versions supported by the cmake server. These are JSON objects with "major" and
-"minor" keys containing non-negative integer values. Some versions may be marked
-as experimental. These will contain the "isExperimental" key set to true. Enabling
-these requires a special command line argument when starting the cmake server mode.
-
-Within a "major" version all "minor" versions are fully backwards compatible.
-New "minor" versions may introduce functionality in such a way that existing
-clients of the same "major" version will continue to work, provided they
-ignore keys in the output that they do not know about.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"supportedProtocolVersions":[{"major":0,"minor":1}],"type":"hello"}
-  ]== "CMake Server" ==]
-
-
-Type "handshake"
-^^^^^^^^^^^^^^^^
-
-The first request that the client may send to the server is of type "handshake".
-
-This request needs to pass one of the "supportedProtocolVersions" of the "hello"
-type response received earlier back to the server in the "protocolVersion" field.
-Giving the "major" version of the requested protocol version will make the server
-use the latest minor version of that protocol. Use this if you do not explicitly
-need to depend on a specific minor version.
-
-Protocol version 1.0 requires the following attributes to be set:
-
-  * "sourceDirectory" with a path to the sources
-  * "buildDirectory" with a path to the build directory
-  * "generator" with the generator name
-  * "extraGenerator" (optional!) with the extra generator to be used
-  * "platform" with the generator platform (if supported by the generator)
-  * "toolset" with the generator toolset (if supported by the generator)
-
-Protocol version 1.2 makes all but the build directory optional, provided
-there is a valid cache in the build directory that contains all the other
-information already.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"cookie":"zimtstern","type":"handshake","protocolVersion":{"major":0},
-   "sourceDirectory":"/home/code/cmake", "buildDirectory":"/tmp/testbuild",
-   "generator":"Ninja"}
-  ]== "CMake Server" ==]
-
-which will result in a response type "reply"::
-
-  [== "CMake Server" ==[
-  {"cookie":"zimtstern","inReplyTo":"handshake","type":"reply"}
-  ]== "CMake Server" ==]
-
-indicating that the server is ready for action.
-
-
-Type "globalSettings"
-^^^^^^^^^^^^^^^^^^^^^
-
-This request can be sent after the initial handshake. It will return a
-JSON structure with information on cmake state.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"type":"globalSettings"}
-  ]== "CMake Server" ==]
-
-which will result in a response type "reply"::
-
-  [== "CMake Server" ==[
-  {
-    "buildDirectory": "/tmp/test-build",
-    "capabilities": {
-      "generators": [
-        {
-          "extraGenerators": [],
-          "name": "Watcom WMake",
-          "platformSupport": false,
-          "toolsetSupport": false
-        },
-        <...>
-      ],
-      "serverMode": false,
-      "version": {
-        "isDirty": false,
-        "major": 3,
-        "minor": 6,
-        "patch": 20160830,
-        "string": "3.6.20160830-gd6abad",
-        "suffix": "gd6abad"
-      }
-    },
-    "checkSystemVars": false,
-    "cookie": "",
-    "extraGenerator": "",
-    "generator": "Ninja",
-    "debugOutput": false,
-    "inReplyTo": "globalSettings",
-    "sourceDirectory": "/home/code/cmake",
-    "trace": false,
-    "traceExpand": false,
-    "type": "reply",
-    "warnUninitialized": false,
-    "warnUnused": false,
-    "warnUnusedCli": true
-  }
-  ]== "CMake Server" ==]
-
-
-Type "setGlobalSettings"
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-This request can be sent to change the global settings attributes. Unknown
-attributes are going to be ignored. Read-only attributes reported by
-"globalSettings" are all capabilities, buildDirectory, generator,
-extraGenerator and sourceDirectory. Any attempt to set these will be ignored,
-too.
-
-All other settings will be changed.
-
-The server will respond with an empty reply message or an error.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"type":"setGlobalSettings","debugOutput":true}
-  ]== "CMake Server" ==]
-
-CMake will reply to this with::
-
-  [== "CMake Server" ==[
-  {"inReplyTo":"setGlobalSettings","type":"reply"}
-  ]== "CMake Server" ==]
-
-
-Type "configure"
-^^^^^^^^^^^^^^^^
-
-This request will configure a project for build.
-
-To configure a build directory already containing cmake files, it is enough to
-set "buildDirectory" via "setGlobalSettings". To create a fresh build directory
-you also need to set "currentGenerator" and "sourceDirectory" via "setGlobalSettings"
-in addition to "buildDirectory".
-
-You may a list of strings to "configure" via the "cacheArguments" key. These
-strings will be interpreted similar to command line arguments related to
-cache handling that are passed to the cmake command line client.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"type":"configure", "cacheArguments":["-Dsomething=else"]}
-  ]== "CMake Server" ==]
-
-CMake will reply like this (after reporting progress for some time)::
-
-  [== "CMake Server" ==[
-  {"cookie":"","inReplyTo":"configure","type":"reply"}
-  ]== "CMake Server" ==]
-
-
-Type "compute"
-^^^^^^^^^^^^^^
-
-This request will generate build system files in the build directory and
-is only available after a project was successfully "configure"d.
-
-Example::
-
-  [== "CMake Server" ==[
-  {"type":"compute"}
-  ]== "CMake Server" ==]
-
-CMake will reply (after reporting progress information)::
-
-  [== "CMake Server" ==[
-  {"cookie":"","inReplyTo":"compute","type":"reply"}
-  ]== "CMake Server" ==]
-
-
-Type "codemodel"
-^^^^^^^^^^^^^^^^
-
-The "codemodel" request can be used after a project was "compute"d successfully.
-
-It will list the complete project structure as it is known to cmake.
-
-The reply will contain a key "configurations", which will contain a list of
-configuration objects. Configuration objects are used to destinquish between
-different configurations the build directory might have enabled. While most
-generators only support one configuration, others might support several.
-
-Each configuration object can have the following keys:
-
-"name"
-  contains the name of the configuration. The name may be empty.
-"projects"
-  contains a list of project objects, one for each build project.

+Source file extensions must be explicit.
+
+In CMake 3.19 and below, if a source file could not be found by the name
+specified, it would append a list of known extensions to the name to see if
+the file with the extension could be found. For example, this would allow the
+user to run:
+
+.. code-block:: cmake
+
+  add_executable(exe main)
+
+and put ``main.c`` in the executable without specifying the extension.
+
+Starting in CMake 3.20, CMake prefers all source files to have their extensions
+explicitly listed:
+
+.. code-block:: cmake
+
+  add_executable(exe main.c)
+
+The ``OLD`` behavior for this policy is to implicitly append known extensions
+to source files if they can't be found. The ``NEW`` behavior of this policy is
+to not append known extensions and require them to be explicit.
+
+This policy was introduced in CMake version 3.20.  CMake version |release|
+warns when the policy is not set and uses ``OLD`` behavior. Use the
+:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.

+
+Ninja generators transform ``DEPFILE`` s from :command:`add_custom_command`.
+
+In CMake 3.19 and below, files given to the ``DEPFILE`` argument of
+:command:`add_custom_command` were passed directly to Ninja's ``depfile``
+variable without any path resolution. This meant that if
+:command:`add_custom_command` was called from a subdirectory (created by
+:command:`add_subdirectory`), the ``DEPFILE`` argument would have to be either
+an absolute path or a path relative to :variable:`CMAKE_BINARY_DIR`, rather
+than :variable:`CMAKE_CURRENT_BINARY_DIR`. In addition, no transformation was
+done on the file listed in ``DEPFILE``, which meant that the paths within the
+``DEPFILE`` had the same restrictions.
+
+Starting with CMake 3.20, the ``DEPFILE`` argument is relative to
+:variable:`CMAKE_CURRENT_BINARY_DIR` (unless it is absolute), and the paths in
+the ``DEPFILE`` are also relative to :variable:`CMAKE_CURRENT_BINARY_DIR`.
+CMake automatically transforms the paths in the ``DEPFILE`` (unless they are
+absolute) after the custom command is run. The file listed in ``DEPFILE`` is
+not modified in any way. Instead, CMake writes the transformation to its own
+internal file, and passes this internal file to Ninja's ``depfile`` variable.
+This transformation happens regardless of whether or not ``DEPFILE`` is
+relative, and regardless of whether or not :command:`add_custom_command` is
+called from a subdirectory.
+
+The ``OLD`` behavior for this policy is to pass the ``DEPFILE`` to Ninja
+unaltered. The ``NEW`` behavior for this policy is to transform the ``DEPFILE``
+after running the custom command.
+
+This policy was introduced in CMake version 3.20.  Unlike most policies,
+CMake version |release| does *not* warn by default when this policy is not set
+(unless ``DEPFILE`` is used in a subdirectory) and simply uses ``OLD``
+behavior.  See documentation of the
+:variable:`CMAKE_POLICY_WARNING_CMP0116 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
+variable to control the warning.

+.. versionadded:: 3.20
+
+MSVC RTTI flag ``/GR`` is not added to
+:variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` by default.
+
+When using MSVC-like compilers in CMake 3.19 and below, the RTTI flag
+``/GR`` is added to :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` by
+default.  This behavior is left from support for MSVC versions from Visual
+Studio 2003 and below that did not enable RTTI by default.  It is no longer
+necessary.  Furthermore, it is problematic for projects that want to change
+to ``/GR-`` programmatically.  In particular, it requires string editing of
+the :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` variable with knowledge
+of the CMake builtin default so it can be replaced.
+
+CMake 3.20 and above prefer to leave out ``/GR`` from the value of
+:variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` by default.
+
+This policy provides compatibility with projects that have not been updated
+to expect the lack of the ``/GR`` flag.  The policy setting takes effect as
+of the first :command:`project` or :command:`enable_language` command that
+initializes :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>`.
+
+.. note::
+
+  Once the policy has taken effect at the top of a project for a given
+  language, that choice must be used throughout the tree for that language.
+  In projects that have nested projects in subdirectories, be sure to
+  convert everything together.
+
+The ``OLD`` behavior for this policy is to place the MSVC ``/GR`` flag in the
+default :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` cache entry.  The
+``NEW`` behavior for this policy is to *not* place the MSVC ``/GR`` flag in
+the default cache entry.
+
+This policy was introduced in CMake version 3.20.  Use the
+:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
+Unlike many policies, CMake version |release| does *not* warn
+when this policy is not set and simply uses ``OLD`` behavior.
