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
|
||||

||||
