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.
