There was a bug report with Debian 11's CMake 3.18.4.[1] It was valuable as it made me spot issues that were bugs with a new CMake too. Since the build process didn't complain about CMake 3.18, the reporter didn't have a reason to check Debian backports. LTS distros with old CMake: - Ubuntu 20.04 has 3.16.3 (no backports) - CentOS 7 has 3.17.5 in EPEL Kitware provides Ubuntu 20.04 repository with CMake for x86-64 and 32/64-bit ARM.[2] But people might not want to use third-party repositories. There weren't any comments in the CMake thread on GitHub[3] and no one has objected on xz-devel so far either. Considering that Autotools support isn't going away anytime soon, I think requiring CMake 3.20 is fine.
