Comment (by rmottola):

 I am actually building with clang 7, but yes, the max gcc I have is 7...
 should I try building gcc8? from the post you cite it should fix stuff.


 {{{
 //C compiler
 CMAKE_C_COMPILER:STRING=/opt/local/bin/clang-mp-7.0
 }}}

 I tried my luck by adding it here:
 CMAKE_EXE_LINKER_FLAGS:STRING=-Wl,-headerpad_max_install_names
 -L/opt/local/lib -lMacportsLegacySupport -lstdc++fs

 But I couldn't get it to work, since what is broken is the cmake test
 itself and there I have little difference. The test is not friendly
 towards older systems :(
