BUG: the modules shipped with cmake don't need

CMAKE_MINIMUM_REQUIRED(VERSION), because the cmake they are shipped with is
always ok. Additionally, if a Find-module does CMAKE_MINIMUM_REQUIRED(), it
changes the policies as they may be set up by the project. So this shouldn't
be done in a Find-module (or surrounded by policy-push/pop commands)
