I think this is the same issue encountered in wreport c++17, fixed in meson.build with

# std::filesystem library needs to be explicitly linked with g++ < 9.0
if cpp.find_library('stdc++fs').found()
  # without this, std::filesystem is not present for some compilers
  add_project_link_arguments(['-lstdc++fs'], language : 'cpp')
endif

But I don't know a quick fix in autotools.

I started a meson branch porting meteosatlib to meson.

Code builds and tests pass. Tomorrow I'll try to look into installation and packaging
