The OLD behavior for this policy is +to follow the symlinks. The NEW behavior for this policy is not to +follow the symlinks by default, but only if FOLLOW_SYMLINKS is given +as an additional argument to the FILE command. + +This policy was introduced in CMake version 2.6.2. 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. |
