Thanks. I looked at the change and see a couple few issues:

1. The change is stale now and needs to be rebased.
2. We don't want to switch from libstdc++ to libc++ everywhere. Instead, we should detect when libstdc++ is used and only then link with the filesystem library for libstdc++.

Please did you mean
we should detect when libstdc++ is used and only then link with the filesystem library for libc++ ?

We should check if libstdc++ is being used and if yest, link with the filesystem library for libstdc++

Hello @kuhar , sorry it took a while, I am still trying to get around CMake. Please is this the right approach ?

if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU")  
    set(FILESYSTEM_LIB_NAME stdc++fs)

This PR does not seem to be moving forward. Closing so that it does not get mistaken as 'approved'.
