I don't really understand this argument: We are cross-compiling some
tens of C++ projects already, whereas adding Rust is a first here. From
my point of view, this is certainly the bigger "burden" here, as long
as we make CMake behave.

That's not true, we can use the version from el7 (which we use for
something else already, I forgot which package). This offers us CMake
3.17.5 from the "official" repos (for some definition of "official").
