Which binaries use a particular class?

I am working with a large mono-repo project that builds several target binaries from a slew of common classes in addition to some clearly delineated code for each binary.  Not every binary makes use of every "common" class.  How can I use the CLion IDE to determine which binaries actually make use of a class?  The reason being, we'd like to make sure we're testing everything we need to after a re-build, but minimize what we test.  

I guess the best we can do is get a clean build, make the changes to said class, then rebuild and see which targets are updated.  There's nothing more elegant in the IDE that I am missing, right?
