How do I get build info for a package that no longer include a pkg_config file?

[Langer, Stephen A. (Fed)]

Hi --

I got a notice that my library, oofcanvas, no longer builds properly.   It fails because cmake is not finding the pkg_config  file for py311-gobject3.
According to ticket 72209 (for port avahi) this is because py311-gobject3 now is compiled as a python wheel.  I’m not familiar with wheels and am having trouble finding  out how to get the compiler and linker flags and installation directories that are needed to link to py311-gobject3.

“port contents py311-gobject3” doesn’t list anything that looks like it will help, despite containing a WHEEL file.

Ticket #72209 says that avahi needs to modify its configure.ac file, but doesn’t say how to get the information that it needs about gobject3.

oofcanvas ticket:  https://trac.macports.org/ticket/72322
explanation here: https://trac.macports.org/ticket/72209

I don’t know if this  a macports, cmake, or gobject issue, but I had to start asking somewhere!

Thanks,
       Steve
