[cmake-developers] ExternalProject and git clone

[David Cole]

2.8.0 is sufficiently high. (The answer is right there in the first 
sentence of the policy help text.) ExternalProject was also introduced 
in 2.8.0, so most projects using it should already be doing:

    cmake_minimum_required(VERSION 2.8)

And if they do, then all policies that are in place as of that version 
should be set to new by that line.
