We declare
cmake_minimum_required(VERSION 2.6.2)
but we also use
cmake_policy(VERSION 2.8.4)
to declare that our CMake scripts are OK with all the defaults of CMake policies
as of CMake-2.8.4. That shuts down the warnings of CMake-2.8.4.
That way, we no longer need any declaration of specific policies.
The documentation of CGAL says that the minimal version of CMake must be
CMake-2.6.2.
- change cmake_minimum_required to VERSION 2.6.2
- no longer any need for the policy CMP0003 (was for 2.4.x)
- no longer any need for CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS (was for 2.4)
