"failed on loading library A" is not very descriptive.  How exactly does
it fail?  g-ir-scanner uses the pkg-config files to link a small program
that introspects GOBject's and if you're library A does not provide one
or it's not passed to g-ir-scanner, then the linking (or running the
application) may fail.

Side note: what does this library do?  Would it be useful to include
upstream?

g-ir-scanner builds the GObject-Introspection information so that one
can use the GStreamer GL library from other languages like python or
vala or javascript or whatever language there are binding generators for.
