@henningw Even if that's the case though, `Buster` is EOL since June 2024. Most should upgrade right in the near future?
So, the supported oldest LTS currently offer: - Debian 11 (bullseye) : `3.18` https://packages.debian.org/bullseye/cmake - Ubuntu 20.04 (focal): `3.16` https://launchpad.net/ubuntu/focal/+source/cmake - CentOS 9: `3.20` https://mirror.stream.centos.org/9-stream/AppStream/x86_64/os/Packages/
So, I guess still no `3.20` available for all of the current/oldest LTS releases. `3.13` is a good candidate indeed and maybe `3.16` if we want the most updated supported by all of them.
