That's true, but we're not using it as a C library, but rather via /usr/bin/g-ir-scanner.

If I was spending time on this, I would patch build systems like autotools
and cmake to, when failing to find a pkg-config file, detect the distribution
and automatically spit out a compatible package name.

The other thing of course is to look at .spec files and such upstream,
and in this case since libhif is already packaged, `yum-builddep libhif`.
