Yeah, that is true, but to be realistic: We do commercial software 
development
and even need to stick with RHEL 7 and we do what everybody else does:

Just install a proper cmake during both the CI and the normal 
development.

We even install our own compilers or at least the latest devtoolset,
otherwise RHEL 7 is useless.

I don't think the enterprise distros are anything we should really look 
at
for determining our dependency versions.
