Please lets not start this discussion again. We decided that the minimum cmake version for now is 3.10. This was commited in [ad35c24](https://github.com/kamailio/kamailio/commit/ad35c24196c921a3e870f4a48b6d2867...).
Just to correct my wrong statement from some weeks ago. It was discussed that the minimum cmake version will be 3.13 ([link](https://github.com/kamailio/kamailio/issues/4078#issuecomment-2553148148)). Thanks @xkaraman for pointing this out to me.
