| ``CMAKE_BACKWARDS_COMPATIBILITY`` should no longer be used. |
| The behavior is to check ``CMAKE_BACKWARDS_COMPATIBILITY`` and present |
| it to the user. The ``NEW`` behavior is to ignore |
| CMAKE_BACKWARDS_COMPATIBILITY completely. |
| In CMake 2.4 and below the variable ``CMAKE_BACKWARDS_COMPATIBILITY`` was |
| used to request compatibility with earlier versions of CMake. In |
| CMake 2.6 and above all compatibility issues are handled by policies |
| and the :command:`cmake_policy` command. However, CMake must still check |
| ``CMAKE_BACKWARDS_COMPATIBILITY`` for projects written for CMake 2.4 and |
| This policy was introduced in CMake version 2.6.0. 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. |
