While +some scripts intend to affect the policies of their includer, most do +not. In CMake 2.6.3 and above, include() and find_package() by +default PUSH and POP an entry on the policy stack around an included +script, but provide a NO_POLICY_SCOPE option to disable it. This +policy determines whether or not to imply NO_POLICY_SCOPE for +compatibility. The OLD behavior for this policy is to imply +NO_POLICY_SCOPE for include() and find_package() commands. The NEW +behavior for this policy is to allow the commands to do their default +cmake_policy PUSH and POP. + +This policy was introduced in CMake version 2.6.3. CMake version +|release| warns when the policy is not set and uses OLD behavior. Use +the cmake_policy command to set it to OLD or NEW explicitly. |
