The CMake variable CMAKE_INSTALL_PREFIX controls the install location
(see install instructions). It's honoured by the python install. You
can independently set PYTHON_PREFIX if you want.

If you want to do it more easily, just set the CMake variables
PYTHON_EXECUTABLE, etc. (they are listed if you "grep -i
CMakeCache.txt").
