What is interesting is: I am the second contributor to the pkgconf project, we
were iirc the first big project to entirely switch to pkgconf and we never ever
needed share/pkgconfig, after digging back in history I can see it was there
since forever, and when I performed the switch from pkg-config to pkgconf and
never ever reintroduced anything but libdata/pkgconfig (our equivalent of
lib/pkgconfig), so this would be the first use case.

And yes the auto population of libdata/pkgconfig is done by moving the files
from lib/pkgconfig not moving the files from share/pkgconfig.

I will add support for share/pkgconfig asap.

Thank for the pointer.

Best regards,
