Kefu Chai e6c7e0f521 cmake: extract std::filesystem linkage checking into module ... see https://libcxx.llvm.org/docs/UsingLibcxx.html#using-libc-experimental-and-experimental, > Note that as of libc++ 7.0 using the <experimental/filesystem> > requires linking libc++fs instead of libc++experimental. do not build ceph_test_admin_socket_output if we are not able to find the library for std::experimental::filesystem . it is a workaround of https://reviews.freebsd.org/D10840 where FreeBSD 11.2 does not ship libc++experimental.a .
