``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 | |
below. | |
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. | |
