PS: Autotools also loves to autodetect random libraries that happen to be 
installed on the system. It is in no way specific to CMake.

Usually -DSOME_VARIABLE=/some/path is the way, look in FindPython.cmake for 
the variables it uses. (First, try to figure out whether RPM is using a 
system-installed FindPython or its own custom version, so you look at the 
correct version.) But the safest (for all build systems) is to always build 
in a mock chroot with only the expected BuildRequires installed, as I have 
written.
