Note that pkg-config support was added 3 years ago for GEOS 3.9.0 via
https://github.com/libgeos/geos/pull/349

In that PR I mention that geos-config could potentially be deprecated,
since there are now two tools that overlap. Now that GEOS 3.8.x has
reached its EOL, maybe it's time to consider this? (If so, I'll start
the GEOS issue for it.)

The only thing that geos-config has over pkg-config is the ability to
link to the C++ API, which nobody should be doing anyways since the C
API is preferred.
