It's related to the scope of the policy and the context of the macro, which 
is a bit counterintuitive.

Your options are:

1) 
Set the policy in KDE4Internal.cmake, like the rest of the policies.

2) 
Apply a patch equivalent to:

 diff --git a/CMakeLists.txt b/CMakeLists.txt
 index b93f190..134181c 100644
 --- a/CMakeLists.txt
 +++ b/CMakeLists.txt

Thanks,
