now that we stick to some outdated py version, some distro (like current debian testing) will feature several python3 dev package, but other dependant libs like numpy are only built against current default version of python (3.8 now in deb testing)... In order to be able to use distro packages we need to allow using higher versions of python, and set relevant CMake option accordingly.
