The HAVE_FLAG_SEARCH_PATHS_FIRST option has nothing to do with this.
It affects the "-Wl,-search_paths_first" option that is first on the
command line that gives the error:

This caused Dave to accidentally misread your original problem.

The -headerpad_max_install_names flag is actually to the *linker* but
the gcc compiler knows how to pass it through.  If we use

  -Wl,-headerpad_max_install_names

instead then pgcc should also pass it through.  Try applying the patch
below to your CMake installation's Modules directory.
