[CMake] Getting the path to object files?

[Robert Maynard]

You can file an enhancement request that the $<TARGET_OBJECTS>
generator expression to be relaxed to include STATIC, SHARED, and
MODULE libraries.

My suggestion is that a dummy source file to workaround the Xcode
limitation on targets, is not as hacky
as reverse engineering the object file locations.
