Comment:
Rebasing should allow you to drop everything outside of the original scope of this PR. Thanks for your participation in improving the build helpers to make mesonpy builds less painful.

Whereas your pybind11 change put cmake and pkg-config files in `/usr/lib`, I kept them in `/usr/share` simply because they are in `share/` in the python package hierarchy. Hopefully this doesn't cause any problems with contourpy. (Most packages favor `/usr/lib` over `/usr/share` for these files, but there are some that stick to `/usr/share`.) We can move them if it causes a problem.
