[CMake] CMP0043 policy warning

[Petr Kmoch]

Hi Scott.

Policy state is changed by explicit calls to cmake_policy() and implicitly
by calls to cmake_minimum_required(). So you need to set the policy to the
setting you want whenever each of these occurs (or modify them so that they
set the policy the way you want it).

The documentation of cmake_policy() has details about this, including how
the policy stack works. You should be able to find more info there.
