+Included scripts do automatic cmake_policy PUSH and POP.
+
+In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by
+the include() and find_package() commands would affect the includer.
+Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were
+required to isolate policy changes and protect the includer. 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.
