Thanks, that's a detail that I seem to have unlearned! The comparison
should have been:

- https://packages.debian.org/bullseye/libproj19 - PROJ 7 via Autotools
- https://packages.debian.org/bookworm/libproj25 - PROJ 9 via CMake

which have comparable file sizes. Also, I can confirm Even's guess
about debug symbols. Run this:

strip --strip-debug /path/to/libproj.so.22.2.1

and the resulting file will be about 5 MB.
