@hansely with the filesystem should the link library be added if experimental only - stdc++fs?

RPP adding here -

rpp/CMakeLists.txt

Line 180 in b4210f1

set(LINK_LIBRARY_LIST ${LINK_LIBRARY_LIST} stdc++fs)

Should we first find filesystem and then link if experimental?

[hansely]

stdc++fs linking is only needed for older compiler.
Newer compilers (GCC >= 9, Clang >= 9, MSVC >= 2017) doesn't require linking.

Macros could be used to check if filesystem is available.
