For my custom language I want to be able to add libraries to the scope. Even though I can add a library, and it will index all the files, and references/go to declaration all work. Find usages doesn't work because the library is not considered "in scope". When I work with the scope tool, I have not found a way to include the library files in the search scope.
Does this questions make sense? How can I include the source files in a library in the search scope?
I have even tried implementing the various Library extensions. They did provide a nice icon for libraries of my custom language, but didn't help the search scope issue.
