<filesystem> is a C++17 addition. In C++11 and C++14 modes, we actually have all the code for <filesystem> but it is hidden behind a non-inline namespace __fs so it is not accessible. Instead of doing this unusual dance, just guard the code for filesystem behind a classic C++17 check like we normally do.
