 The default on 8 is not too bad, but you should not use the default on 7. Use the EPEL package instead.

-Personally, on Linux, I put versions of CMake in folders, like `/opt/cmake312` or `~/opt/cmake312`, and then add them to [LMod]. See [`envmodule_setup`][envmodule_setup] for help setting up an LMod system on macOS or Linux. It takes a bit to learn, but is a great way to manage package and compiler versions.
