Certainly easy to do...

This is probably the better long term solution since it doesn't require
CMakeLists writers to worry about it. I'll add it to my to-do list. I don't
think it is too difficult to implement, not trivial but not a killer.
Basically I'll change the internal workings of how executables are handled
(since they are the less complex case). Some commands like
SET_TARGET_PROPERTIES will need an option to disambiguate targets when there
are both libs and exe with the same name.
