Here are a few more dependency generators that have been in use for
years that you might take inspiration from:

https://src.fedoraproject.org/rpms/nbdkit/blob/rawhide/f/nbdkit-find-provides
https://src.fedoraproject.org/rpms/nbdkit/blob/rawhide/f/nbdkit.attr

https://src.fedoraproject.org/rpms/supermin/blob/rawhide/f/supermin-find-requires
https://src.fedoraproject.org/rpms/supermin/blob/rawhide/f/supermin.attr

https://github.com/rpm-software-management/rpm/blob/master/scripts/ocamldeps.sh
https://github.com/rpm-software-management/rpm/blob/master/fileattrs/ocaml.attr

I do see a few 'exit 1' in those :-(
