On second thought, I think there can still be cases where the warning will
appear with CMP0003 set to NEW, but not this one.

The messages also point you at documentation which explains what is going on.
Only the CMP0003 warning tells you what code to put in, and I only did that
because so many people complained about the warning text.  Any project that
does "cmake_minimum_required(VERSION 2.6)" will never see CMP0003 again
(assuming there are no places the command is invoked with 2.4).
