I've noticed these differences for a while too. You can see it with
Debian distributions which show package and installed size:

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

My observation is that autotools builds tend to take up more disk
space for C++ projects. (For comparison, see
https://packages.debian.org/buster/libproj-dev for PROJ 5 via
Autotools when it was a C-only library).

Hopefully someone has a better informed answer!
