+FindFilesystem
+##############
+
+This module supports the C++17 standard library's filesystem utilities. Use the
+:imp-target:`std::filesystem` imported target to
+
+Options
+*******
+
+The ``COMPONENTS`` argument to this module supports the following values:
+
+.. find-component:: Experimental
+    :name: fs.Experimental
+
+    Allows the module to find the "experimental" Filesystem TS version of the
+    Filesystem library. This is the library that should be used with the
+    ``std::experimental::filesystem`` namespace.
+
+.. find-component:: Final
+    :name: fs.Final
+
+    Finds the final C++17 standard version of the filesystem library.
+
+If no components are provided, behaves as if the
+:find-component:`fs.Final` component was specified.
+
+If both :find-component:`fs.Experimental` and :find-component:`fs.Final` are
+provided, first looks for ``Final``, and falls back to ``Experimental`` in case
+of failure. If ``Final`` is found, :imp-target:`std::filesystem` and all
+:ref:`variables <fs.variables>` will refer to the ``Final`` version.
+
+
+Imported Targets
+****************
+
+.. imp-target:: std::filesystem
+
+    The ``std::filesystem`` imported target is defined when any requested
+    version of the C++ filesystem library has been found, whether it is
+    *Experimental* or *Final*.
+
+    If no version of the filesystem library is available, this target will not
+    be defined.
+
+    .. note::
+        This target has ``cxx_std_17`` as an ``INTERFACE``
+        :ref:`compile language standard feature <req-lang-standards>`. Linking
+        to this target will automatically enable C++17 if no later standard
+        version is already required on the linking target.
+
+
+.. _fs.variables:
+
+Variables
+*********
+
+.. variable:: CXX_FILESYSTEM_IS_EXPERIMENTAL
+
+    Set to ``TRUE`` when the :find-component:`fs.Experimental` version of C++
+    filesystem library was found, otherwise ``FALSE``.
+
+.. variable:: CXX_FILESYSTEM_HAVE_FS
+
+    Set to ``TRUE`` when a filesystem header was found.
+
+.. variable:: CXX_FILESYSTEM_HEADER
+
+    Set to either ``filesystem`` or ``experimental/filesystem`` depending on
+    whether :find-component:`fs.Final` or :find-component:`fs.Experimental` was
+    found.
+
+.. variable:: CXX_FILESYSTEM_NAMESPACE
+
+    Set to either ``std::filesystem`` or ``std::experimental::filesystem``
+    depending on whether :find-component:`fs.Final` or
+    :find-component:`fs.Experimental` was found.
+
+
+Examples
+********
