I don't recall one off the top of my head.  Even if there were,
the `set_property(TEST ...)` only works on tests in the invoking
directory.  There is no global scope for test names.

Some projects use a `myproj_add_test()` wrapper around their
`add_test()` calls specifically to provide customizations.
