 extra line in the Portfile (`legacysupport.use_mp_libcxx yes`) is better
 than patching the source code to use another filesystem library?

 Thanks for this PR proposal.  I manually applied that change to my local
 port file on macOS 10.14 (sudo port edit poppler), and poppler built
 successfully from source.  Which is handy because a bunch of other ports
 depend on poppler (and want to pull in a later poppler :-/ )

 To me too this seems like the cleanest work around for poppler wanting
 newer C++ features than macOS 10.14 shipped with.
