4Do not re-expand variables in include and link information.

6CMake 2.8.10 and lower re-evaluated values given to the
7include_directories, link_directories, and link_libraries commands to
8expand any leftover variable references at the end of the
9configuration step.  This was for strict compatibility with VERY early
10CMake versions because all variable references are now normally
11evaluated during CMake language processing.  CMake 2.8.11 and higher
12prefer to skip the extra evaluation.

14The ``OLD`` behavior for this policy is to re-evaluate the values for
15strict compatibility.  The ``NEW`` behavior for this policy is to leave
16the values untouched.
17
18This policy was introduced in CMake version 2.8.11.  CMake version
19|release| warns when the policy is not set and uses ``OLD`` behavior.  Use
20the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
