No C++ support for std::filesystem #1210

Closed yurivict closed 2 years ago

CMake Error at cmakemodules/FindFilesystem.cmake:73 (message):
  No C++ support for std::filesystem
Call Stack (most recent call first):
  libs/system/CMakeLists.txt:4 (find_package)

std::filesystem is supported by the compiler.

It is looking for libstdc++fs, but on FreeBSD the library name is libc++.

clang-12 OS: FreeBSD 13

@yurivict Thanks! It's fixed now in #1212

Note however that further build errors are found by the actual compilation: mrpt-core cannot be built due to clang not finding basic headers like <string>. I tried playing with -stdlib=xxx without luck... Any help on this and/or PRs would be appreciated!
