CMP0001 ------- .. |REMOVED_IN_CMAKE_VERSION| replace:: 4.0 .. include:: include/REMOVED_PROLOGUE.rst ``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. .. |INTRODUCED_IN_CMAKE_VERSION| replace:: 2.6.0 .. |WARNED_OR_DID_NOT_WARN| replace:: warned .. include:: include/REMOVED_EPILOGUE.rst
