upgrading cmake - #950

is there a particular reason to upgrade cmake?

the mingw ci job failures seem unrelated.

I am for upgrading cmake. But it feels somewhat odd that we hold ourselves back to C++11 while demanding a cmake released 2023.

@pauldreik We don't have to upgrade.

This can be revisited. Although, of course, it would require a major release.

I don't think we can require anything beyond C++20, however. Yet C++20 would be fine. We could have two tracks, maintain security patches for the current version, and go C++20 with a new major release.

I think this sounds like a good proposal - switch to C++20 and a more modern cmake in the next major release, and possibly do security patches on the current release, for those needing to stay on C++11.
