I've added another patch to my clone to solve this problem:
Export link implementation as old link interface if it does not contain
generator expressions.
That way,
target_link_libraries(foo bar)
will export the old and new link interfaces, and
target_link_libraries(foo $<1:bar>)
will export only the new one, which is appropriate anyway because only that
can handle the generator expressions.
Thanks,
Steve.
