Title: cmake: Avoid python dependency on non-Mac systems

On Linux systems, with Linuxbrew, the current cmake build recipe will pull in Python and a large number of other system packages that Python depend on. This can cause some bad library dependency issues. This small fix skips the Python install on these systems. Thanks much.
