CMake version ignored

[dzenanz]

Despite explicitly getting CMake 3.24 in the CI, an older version is used during some stage resulting in insufficient version error:

This might be a problem in https://github.com/python-cmake-buildsystem/python-cmake-buildsystem.

It looks like this will require digging to diagnose. If @jcfr or @thewtex have suggestions to steer me, it would be appreciated.

[thewtex]

@dzenanz cmake is provided in the Linux Docker images via dockcross, so it may need to be bumped there.

@dzenanz Thanks for the fix. Was this resolved in #212?

[dzenanz]

No, I don't think it did. It just bumps CMake version inside dockcross.

[tbirdso]

Got it, I misunderstood, thanks.

[thewtex]

The CMake version is not expected to come from the host system.
