-.. versionadded:: 3.19
-
-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 `APPEND`_ and
-`CMAKE_PATH`_ 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(APPEND) <APPEND>` command. Can be used to build a path from
-   already available path fragments.
-3. :ref:`cmake_path(CMAKE_PATH) <CMAKE_PATH>` command. Mainly used to build a
-   path variable from a native path.
-
-  .. code-block:: cmake
-
-    # To build the path "${CMAKE_CURRENT_SOURCE_DIR}/data"
-
-    set (path1 "${CMAKE_CURRENT_SOURCE_DIR}/data")
-
-    cmake_path(APPEND path2 "${CMAKE_CURRENT_SOURCE_DIR}" "data")
-
-    cmake_path(CMAKE_PATH path3 "${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,
-except `CMAKE_PATH`_, store the result in the required ``<out-var>`` variable.
-
-Sub-commands supporting ``NORMALIZE`` option will :ref:`normalize <NORMAL_PATH>`
-the path.

-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 \"${result}\"")
-
-  Will display::
-
-    Parent path is "c:/a"
-    Relative path is "c:/"
-
-Modification
-^^^^^^^^^^^^
-
-.. _APPEND:
-
-.. code-block:: cmake
-
-    cmake_path(APPEND <path-var> [<input>...] [OUTPUT_VARIABLE <out-var>])
-
-Append all the ``<input>`` arguments to the ``<path-var>`` using ``/`` as
-``directory-separator``.
-
-For each ``<input>`` argument, the following algorithm (pseudo-code) applies:
-
-  .. code-block:: cmake
-
-    # <path> is the contents of <path-var>
-
-    IF (<input>.is_absolute() OR
-         (<input>.has_root_name() AND
-          NOT <input>.root_name() STREQUAL <path>.root_name()))
-      replaces <path> with <input>
-      RETURN()
-    ENDIF()
-
-    IF (<input>.has_root_directory())
-      remove any root-directory and the entire relative path from <path>
-    ELSEIF (<path>.has_filename() OR
-             (NOT <path-var>.has_root_directory() OR <path>.is_absolute()))
-      appends directory-separator to <path>
-    ENDIF()
-
-    appends <input> omitting any root-name to <path>
-
-.. _CONCAT:
-
-.. code-block:: cmake
-
-    cmake_path(CONCAT <path-var> [<input>...] [OUTPUT_VARIABLE <out-var>])
-
-Concatenates all the ``<input>`` arguments to the ``<path-var>`` without
-``directory-separator``.
-
-.. _REMOVE_FILENAME:
-
-.. code-block:: cmake
-
-    cmake_path(REMOVE_FILENAME <path-var> [OUTPUT_VARIABLE <out-var>])
-
-Removes the :ref:`filename <FILENAME_DEF>` component (as returned by
-:ref:`GET ... FILENAME <GET_FILENAME>`) from ``<path-var>``.
-
-After this function returns, if change is done in-place, `HAS_FILENAME`_
-returns false for ``<path-var>``.
-
-For Example:
-
-  .. code-block:: cmake
-
-    set (path "/a/b")
-    cmake_path (REMOVE_FILENAME path)
-    message ("First path is \"${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 `CONCAT`_ was used.
-
-
-Equivalent to the following:
-
-  .. code-block:: cmake
-
-    cmake_path(REMOVE_EXTENSION path)
-    if (NOT "input" MATCHES "^\\.")
-      cmake_path(CONCAT path ".")
-    endif()
-    cmake_path(CONCAT 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>`_.
-
-.. _PROXIMATE_PATH:
-
-.. code-block:: cmake
-
-    cmake_path(PROXIMATE_PATH <path-var> [BASE_DIRECTORY <input>]
-                                         [OUTPUT_VARIABLE <out-var>])
-
-If the value of `RELATIVE_PATH`_ is not an empty path, return
-it. Otherwise return ``<path-var>``.
-
-If ``BASE_DIRECTORY`` is not specified, the default base directory will be
-:variable:`CMAKE_CURRENT_SOURCE_DIR`.
-
-.. _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-CMAKE_PATH:
-.. _CMAKE_PATH:
-
-.. code-block:: cmake
-
-    cmake_path(CMAKE_PATH <path-var> [NORMALIZE] <input>)
-
-Converts a native ``<input>`` path 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 (CMAKE_PATH path "${native_path}")
-    message ("CMake path is \"${path}\"")
-
-    cmake_path (CMAKE_PATH path NORMALIZE "${native_path}")
-    message ("Normalized CMake path is \"${path}\"")
-
-  Will display::
-
-    CMake path is "c:/a/b/../c"
-    Normalized CMake path is "c:/a/c"
-
-.. _cmake_path-NATIVE_PATH:
-.. _NATIVE_PATH:
-
-.. code-block:: cmake
-
-    cmake_path(NATIVE_PATH <path-var> [NORMALIZE] <out-var>)
-
-Converts a cmake-style ``<path-var>`` into a native
-path with platform-specific slashes (``\`` on Windows and ``/`` elsewhere).
-
-When ``NORMALIZE`` option is specified, the path is :ref:`normalized
-<NORMAL_PATH>` before the conversion.
-
-.. _CONVERT:
-.. _cmake_path-TO_CMAKE_PATH_LIST:
-.. _TO_CMAKE_PATH_LIST:
-
-.. code-block:: cmake
-
-   cmake_path(CONVERT <input> TO_CMAKE_PATH_LIST <out-var> [NORMALIZE])
-
-Converts a native ``<input>`` path into cmake-style path with forward-slashes
-(``/``).  On Windows, the long filename marker is taken into account. The input can
-be a single path or a system search path like ``$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.

-.. _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 <path-var> EQUAL <input> <out-var>)
-    cmake_path(COMPARE <path-var> NOT_EQUAL <input> <out-var>)
-
-Compares the lexical representations of the path and another path.
-
-For testing equality, the following algorithm (pseudo-code) apply:
-
-  .. code-block:: cmake
-
-    # <path> is the contents of <path-var>
-
-    IF (NOT <path>.root_name() STREQUAL <input>.root_name())
-      returns FALSE
-    ELSEIF (<path>.has_root_directory() XOR <input>.has_root_directory())
-      returns FALSE
-    ENDIF()
-
-    returns TRUE or FALSE if the relative portion of <path> is
-      lexicographically equal or not to the relative portion of <input>.
-      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
-empty path).
-
-.. _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
-non-empty path).
-
-.. _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
-without reference to an additional starting location.
-
-.. _IS_RELATIVE:
-
-.. code-block:: cmake
-
-    cmake_path(IS_RELATIVE <path-var> <out-var>)
-
-Checks if path is relative (i.e. not :ref:`absolute <IS_ABSOLUTE>`).
-
-.. _IS_PREFIX:
-
-.. code-block:: cmake
-
-    cmake_path(IS_PREFIX <path-var> <input> [NORMALIZE] <out-var>)
-
-Checks if ``<path-var>`` is the prefix of ``<input>``.
-
-When ``NORMALIZE`` option is specified, the paths are :ref:`normalized
-<NORMAL_PATH>` before the check.
-
-Hashing
-^^^^^^^
-
-.. _HASH:
-
-.. code-block:: cmake
-
-    cmake_path(HASH <path-var> [NORMALIZE] <out-var>)
-
-Compute hash value of ``<path-var>`` such that if for two paths (``p1`` and
-``p2``) are equal (:ref:`COMPARE ... EQUAL <COMPARE>`) then hash value of p1 is
-equal to hash value of p2.
-
-When ``NORMALIZE`` option is specified, the paths are :ref:`normalized
-<NORMAL_PATH>` before the check.
