This is one reason I just fixed the warnings with the "super ugly"
approach on some of the other modules.  It is a cost we pay upstream
to support older clients, but the policy will still allow cleaner
code in applications.

Or, one could add the explicit PUSH/POP in modules, e.g.

 cmake_policy(PUSH)
 cmake_policy(SET CMP0054 NEW)
 ... module code ...
 cmake_policy(POP)
