I'm confused as to where this variable comes from in the first place, because it's not documented and now that I did a clean build, it's gone.

I'm still trying to find a proper way of getting the dll name, there does not seem to be any variable that return the path/name. `Python3_SABI_LIBRARIES` is empty unless `Python3_SABI_LIBRARY` is set.
