cmake 4.0 compatibility #7
Description
Soooo cmake 4.0 decided to drop support for cmakelists with a low minimum_required_version, and a lot of C-dependencies here are below that version (3.5 or so).
Basically it's a pain to recompile anything from scratch now... I had to go into all the submodules and bump it everywhere.
Alternatively this extra flag can be added to cmake invocations, but I didn't get that working yet.
So yeah I was just re-running ptrhash this time so was able to comment things out, but this is sadly gonna cause massive churn to keep things working.
See eg y-256/libdivsufsort#29 for what needs fixing (as far as I'm aware -- I've never written cmake configs).
edit: oh setting the CMAKE_POLICY_VERSION_MINIMUM env var to 3.5 would probably fix it recursively.
