When a new policy is introduced, newer CMake +versions will begin to warn about the backward compatible behavior. It +is possible to disable the warning by explicitly requesting the OLD, or +backward compatible behavior using the :command:`cmake_policy` command. +It is also possible to request NEW, or non-backward compatible behavior +for a policy, also avoiding the warning. + +The :command:`cmake_minimum_required` command does more than report an +error if a too-old version of CMake is used to build a project. It +also sets all policies introduced in that CMake version or earlier to +NEW behavior. + +The :variable:`CMAKE_MINIMUM_REQUIRED_VERSION` variable may also be used +to determine whether to report an error on use of deprecated macros or +functions. + All Policies ============ diff --git a/Help/manual/cmake.1.rst b/Help/manual/cmake.1.rst index 64d0fb3..d026c63 100644 --- a/Help/manual/cmake.1.rst +++ b/Help/manual/cmake.1.rst @@ -33,7 +33,7 @@ native tool on their platform. copy_directory, copy_if_different, echo, echo_append, environment, make_directory, md5sum, remove, remove_directory, rename, tar, time, touch, touch_nocreate.
