There should be no dependencies at build between mfext addons because we don't want to manage triggers in mfext addons.
In this case mfextaddon_python3_ia needs mfextaddon_scientific for numpy and scipy
This dependency is explicit in drone.yml (but there is no trigger to rebuild mfextaddon_python3_ia at the end of the build of mfextaddon_scientific)
