Set CMake policies for newer versions of CMake

paul-elliott-arm · paul-elliott-arm · commit fb75e89ef2c4 · 2020-09-24T16:28:53.000+01:00
Make sure that CMP0012 is set to NEW, without which FindPython3 and
FindPython2 functionality becomes broken with CMake 3.18.2 if searching
by location.  Ensure CMP0011 is set to NEW to avoid warnings being
issued about policy push / pop with CMake 3.18.0 or newer.
