Done, r1142396. Automoc4Config.cmake now also sets CMP0002 to OLD (as the 
error message actually also says).
Since 2.6.3, when invoking a macro or function, the policy settings are active 
as they were at the place where the maco/function was defined, i.e. as they 
are in Automoc4Config.cmake. So we set CMP0002 to OLD here now too, this is 
done already in FindKDE4Internal.cmake, but the 
cmake_minimum_required(VERSION 2.6.4) resets this.
By putting the cmake_policy(PUSH/POP) at the top and bottom of the file we 
ensure that the policy settings don't escape Automoc4Config.cmake.
