It is not a question about code. It is a question about context and use 
case.

Valid context as the documentation states would e.g. be a project that 
is no longer maintained where you have no intention of ever migrating to 
a newer CMake version.
Or as I said cmake's testsuite.

If you insist on actual code e.g. this is part of the tests that I wrote 
for CMP0054:
https://cmake.org/gitweb?p=cmake.git;a=blob;f=Tests/RunCMake/CMP0054/CMP0054-NEW.cmake;h=23a912476024ba09fcf741e04f999b64a6e91450;hb=refs/heads/master

Again the code itself is irrelevant here; what matters is the context.
