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
********
Using `find_package(FILESYSTEM)` with no component arguments:
.. code-block:: cmake
