The VS and Xcode generators do not use those variables, but could be
taught similar changes if this were to be a first-class feature.

Actually having add_executable create something besides cmTarget::EXECUTABLE
could cause other logic changes, even in project code that tests target
types.  Therefore we should probably delay the exe->lib mapping to be
just in the actual link step as above.
