+-------
+
+Disallow include export result.
+
+CMake 2.8.12 and lower allowed use of the include() command with the
+result of the export() command. This relies on the assumption that
+the export() command has an immediate effect at configure-time during
+a cmake run. Certain properties of targets are not fully determined
+until later at generate-time, such as the link language and complete
+list of link libraries. Future refactoring will change the effect of
+the export() command to be executed at generate-time. Use ALIAS
+targets instead in cases where the goal is to refer to targets by
+another name
+
+The OLD behavior for this policy is to allow including the result of
+an export() command. The NEW behavior for this policy is to not to
+allow including the result of an export() command.
+
+This policy was introduced in CMake version 2.8.13. 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.
