i am a little worried about this change. previously we were making sure all the
dependent modules were built within this free function. now we're relying on
the caller ensuring that, without any checks.
can we keep this behavior, but pass in the module-cache as a parameter and skip
building if module-file is available in the cache? later on caller can update
the cache using the information in `BuiltModuleFiles`.
