cmake full-transition memo

[rouault]

What is currently missing in cmake builds:

• [X] make dist target - #2690
• [x] regeneration of src/wkt1_generated_parser.c/.h and src/wkt2_generated_parser.c/.h with bison : those are currently generated with "make wkt1_parser" and "make wkt2_parser" in the $builddir/src directory of a autoconf build: https://github.com/OSGeo/PROJ/pull/2900
• [x] check and migrate CI workflows, e.g. Clang Static Analyzer - #3001
• [x] migrate ossfuzz build: test/fuzzers/build.sh: tracked in https://github.com/OSGeo/PROJ/pull/2896
• [x] downstream users: GDAL CI && ossfuzz : tracked in https://github.com/OSGeo/gdal/issues/4576
• [X] downstream user: libgeotiff: https://github.com/OSGeo/libgeotiff/pull/64
• [x] Dockerfile (used by .github/workflows/docker.yml) needs to change to cmake: https://github.com/OSGeo/PROJ/pull/3018
• [x] revise HOWTO-RELEASE document for relevant changes - #3030
• [X] make uninstall target - https://github.com/OSGeo/PROJ/pull/3362
• [ ] re-implement PROJ_DB_CACHE_DIR from #1446 (c.f. data/Makefile.am)

* `make clean` target

What is missing exactly ? make clean seems to work

I can't recall, as make clean works fine from Makefile generators from CMake 3.10.2. I'll scrub this task off.

[mwtoews]

🤦 (facepalm) it was make uninstall that I was thinking of. Autotools supports this, although it is not tested. Any interest in bringing this to CMake too? It's not too difficult; see how GEOS does this.

Sounds like a nice thing to have
