GenotypeMatrix and External not included in packages argument to setup in setup.py

[bskubi]

After pip installing bsbolt from source code in mamba, GenotypeMatrix and External are not copied to the site-packages/bsbolt folder, and bsbolt throws a module not found error for GenotypeMatrix. I added GenotypeMatrix and External to the list of packages in the setup.py setup function's packages argument, and it works fine.
