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 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 cmake_policy command to set it to OLD or NEW explicitly. |
