Hi @michaelrj-google  I’m separating the subarchive name from its entry-point list in this original implementation. Previously, entry points were selected by including every entry point objects that matched the subarchive name. I’ve now added a CMake cache variable for specifying the entry points explicitly. This provides greater flexibility, allowing the archive to contain only the required routines and giving downstream projects finer control over its contents.

Please have a look and if you are happy with the changes, Please approve this change
