| Disallow include export result. |
| |
| CMake 2.8.12 and lower allowed use of the :command:`include` command with the |
| result of the :command:`export` command. This relies on the assumption that |
| the :command:`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 :command:`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 :command:`export` command. The ``NEW`` behavior for this policy is not to |
| allow including the result of an :command:`export` command. |
| |
| This policy was introduced in CMake version 3.0. CMake version |
| |release| warns when the policy is not set and uses ``OLD`` behavior. Use |
| the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` |
| explicitly. |
