An IMPORTED target may not have an ALIAS. The solution might rather be to 
generate and import two sets of targets. You would need to decide what your 
deprecation strategy is for the old targets, and how much source 
compatibility is needed. Making this change in the future is not going to be 
easier than it is now.

Thanks,
