This is probably a very basic question, and forgive me since Google isn't coming up with what I'm looking for. I'm migrating a project from KDS to MCUXpresso. Many moons ago, I had dependencies working so if a library was rebuilt because of a source change, the main project would be rebuilt to link in the new library. I've set up the projects with the same hierarchy I had in KDS. The main project links in the libraries generated, and has those projects are listed in "project references". It builds the individual libraries OK if I modify a source, but it doesn't automatically rebuild the main. What was the trick to make it aware that the main depends on the others? I've compared settings in KDS, and it appears I have the same settings, but I must be missing something.
