4Disallow include export result.

6CMake 2.8.12 and lower allowed use of the :command:`include` command with the
7result of the :command:`export` command.  This relies on the assumption that
8the :command:`export` command has an immediate effect at configure-time during
9a cmake run.  Certain properties of targets are not fully determined
10until later at generate-time, such as the link language and complete
11list of link libraries.  Future refactoring will change the effect of
12the :command:`export` command to be executed at generate-time.  Use ``ALIAS``
13targets instead in cases where the goal is to refer to targets by
14another name.

16The ``OLD`` behavior for this policy is to allow including the result of
17an :command:`export` command.  The ``NEW`` behavior for this policy is not to
18allow including the result of an :command:`export` command.
19
20This policy was introduced in CMake version 3.0.  CMake version
21|release| warns when the policy is not set and uses ``OLD`` behavior.  Use
22the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW``
23explicitly.
