How to use the cmake.tribits.ci_support.TribitsDependencies.DepStats function in cmake

    # (i.e. libsOnly=True) or if this is the top-level package.  The tests for
    # dependent packages are not any kind of dependency for tests for the
    # top-level package.  However, we need to record that these are test
    # dependencies so that any package libraries that get recursed are
    # recorded as 'ITR' or 'ITO' and not as library dependencies.
