If you want a reliable mapping, then there needs to be
a well-defined semantic based on some reliable mechanism defined
for the pkgconfig(…) dependency name space.

You have already mentioned 2 mappings, one based on RPMTAG_PROVIDENAME,
the other based on RPMTAG_FILEPATHS (there are several tags here).

There are additional issues with multiple mappings: the mapping is not 1-to-1.

A mapping is quite doable if the semantic is well-defined.
