Didn’t find a magic recipe but I did come up with a workaround. I overrode the
pkg-config command used by configure ala:
set pkg_config_cmd "${prefix}/bin/pkg-config $@ | sed 's|-I${prefix}/include
||g’”
and added --pkg_config="${pkg_config_cmd}” to the configure arguments. I get
one no-harm warning but that is much better than random build failures!
I’m still open to better solutions.
