# By default, without the settings below, find_package(Python3) will attempt
# to find the newest python version it can, and additionally will find the
# most specific version. For instance, on a system that has
# /usr/bin/python3.10, /usr/bin/python3.11, and /usr/bin/python3, it will find
# /usr/bin/python3.11, even if /usr/bin/python3 points to /usr/bin/python3.10.
# The behavior we want is to prefer the "system" installed version unless the
# user specifically tells us othewise through the Python3_EXECUTABLE hint.
# Setting CMP0094 to NEW means that the search will stop after the first
# python version is found. Setting Python3_FIND_UNVERSIONED_NAMES means that
# the search will prefer /usr/bin/python3 over /usr/bin/python3.11. And that
# latter functionality is only available in CMake 3.20 or later, so we need
# at least that version.
