$<IN_LIST:...> handles empty list items.
In CMake 3.13 and lower, the $<IN_LIST:...> generator expression always
returned 0 if the first argument was empty, even if the list contained an
empty item. This behavior is inconsistent with the IN_LIST behavior of
:command:if, which this generator expression is meant to emulate. CMake 3.14
and later handles this case correctly.
The OLD behavior of this policy is for $<IN_LIST:...> to always return
0 if the first argument is empty. The NEW behavior is to return 1
if the first argument is empty and the list contains an empty item.
