Yeah. In particular, RPMs don't magically appear out of nowhere; somebody
has to build them, and more often than not, the somebody is subject to
distro packaging policy that says what build dependencies are allowed.
Red Hat certainly isn't ever going to ship a package that requires some
version of cmake that isn't what they ship in the particular distribution,
for example.
