Thanks. The changes to the Makefile seem to mirror what is done in
contrib/isn/Makefile, but I'm not so sure about the meson.build
changes. sepgsql uses dir_data / 'contrib' rather than
dir_include_server. src/pl/pl{perl,pgsql,python} use
dir_include_server, but they also live in src/pl, not contrib. I don't
think I understand what the underlying principal is supposed to be
here. If you or anyone else knows, please enlighten me.
