+Do not re-expand variables in include and link information.
+
+CMake 2.8.10 and lower re-evaluated values given to the
+include_directories, link_directories, and link_libraries commands to
+expand any leftover variable references at the end of the
+configuration step. This was for strict compatibility with VERY early
+CMake versions because all variable references are now normally
+evaluated during CMake language processing. CMake 2.8.11 and higher
+prefer to skip the extra evaluation.
+
+The OLD behavior for this policy is to re-evaluate the values for
+strict compatibility. The NEW behavior for this policy is to leave
+the values untouched.
+
+This policy was introduced in CMake version 2.8.11. 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.
