[CMake] fixup_bundle on Windows : issue with multiple exe applications

[David Cole]

It was designed originally with the assumption that all the
executables in a bundle are in the same directory. If you violate that
assumption, I don't think you can count on it to do the right thing
100% of the time.

If it works for you calling it multiple times with deepest first, then
maybe you can get lucky...

I would definitely dig into it and understand exactly what it's doing,
though, if you want to make sure it's going to continue working for
your scenario.


HTH,
David C.
