since we still support g++-7, where filesystem is marked experimental, we introduce a wrapper header and expose the namespace to use as Opm::filesystem. for gcc we unconditionally link with libstdc++fs in the python bindings. the setup.py stuff links as c code, not c++ code, so it is not automatically added on any gcc version. this might prove unportable later.
