I've just found the reason why: the CI compares the pc file generated
by autotools against the pc file generated by meson. If they are
different, the pipeline fails.

This is why these values were passed semi-independently for pkgconfig.

I think I have found the way to suppress the discrepancy while letting
CI pass (with default values).
