Or maybe this is expected POST_BUILD behavior?  The executable builds
just fine.  Then a POST_BUILD event is run, and it does whatever.  The
next time we try to build the executable, it's already built, so no
POST_BUILD event is run.  If this is expected behavior, then it should
be documented.  It's easy for a user to get confused and think a
POST_BUILD should behave as a simple dependency.  The docs merely say,
"POST_BUILD - run after the target has been built."
