This is just cmake being extra helpful and finding the latest python 
version on the system. You're explicitly overriding PYTHON_EXECUTABLE so 
that doesn't match what cmake is finding itself. You would also need to 
set an explicit Python_ROOT_DIR or Python_LIBRARIES etc for things that 
need those.
