I've tried to simplify replicating this issue by using the command line version of cmake and the configuration script that can be found here. It is about as simple as possible. There are no obvious errors/warnings from CMake but python3 support remains unavailable. Any help welcomed. How do the CI builds for this environment get configured and build?
