The automatic requires are added based on output of an external program.
You can override which program is used in the spec file. So you could
provide a custom script which calls the original script, and then also
output the extra missing library requires
See the section "requires filtering"
https://fedoraproject.org/wiki/PackagingDrafts/FilteringAutomaticDependencies
instead of filtering you'd be augmenting, but that's fine.
