Which debian stable version are you using?

Debian provides backports repos.

For older stable debian 11 bullseye

https://packages.debian.org/bullseye-backports/cmake

it ships cmake 3.25.

For latest stable debian 12 bookworm

https://packages.debian.org/bookworm-backports/cmake

it ships cmake 3.30.

Is it unreasonable to ask to install cmake from one of those official repos?
