| Introduction |
| ============ |
| |
| CMake policies introduce behavior changes while preserving compatibility |
| for existing project releases. Policies are deprecation mechanisms, not |
| feature toggles. Each policy documents a deprecated ``OLD`` behavior and |
| a preferred ``NEW`` behavior. Projects must be updated over time to |
| use the ``NEW`` behavior, but their existing releases will continue to |
| work with the ``OLD`` behavior. |
| |
| Updating Projects |
| ----------------- |
| |
| When policies are newly introduced by a version of CMake, their ``OLD`` |
| behaviors are immediately deprecated by that version of CMake and later. |
| Projects should be updated to use the ``NEW`` behaviors of the policies |
| as soon as possible. |
| |
| Use the :command:`cmake_minimum_required` command to record the latest |
| version of CMake for which a project has been updated. |
| For example: |
| |
| .. |
| Sync this cmake_minimum_required example with ``Help/dev/maint.rst``. |
| |
| .. code-block:: cmake |
| |
| cmake_minimum_required(VERSION 3.10...4.0) |
| |
| This uses the ``<min>...<max>`` syntax to enable the ``NEW`` behaviors |
| of policies introduced in CMake 4.0 and earlier while only requiring a |
| minimum version of CMake 3.10. The project is expected to work with |
| both the ``OLD`` and ``NEW`` behaviors of policies introduced between |
| those versions. |
| |
| Transition Schedule |
| ------------------- |
| |
| To help projects port to the ``NEW`` behaviors of policies on their own |
| schedule, CMake offers a transition period: |
| |
| * If a policy is not set by a project, CMake uses its ``OLD`` behavior, |
| but may warn that the policy has not been set. |
| |
| * Users running CMake may silence the warning without modifying a |
| project by setting the :variable:`CMAKE_POLICY_DEFAULT_CMP<NNNN>` |
| variable as a cache entry on the :manual:`cmake(1)` command line: |
| |
| .. code-block:: shell |
| |
| cmake -DCMAKE_POLICY_DEFAULT_CMP0990=OLD ... |
| |
| * Projects may silence the warning by using the :command:`cmake_policy` |
| command to explicitly set the policy to ``OLD`` or ``NEW`` behavior: |
| |
| .. code-block:: cmake |
| |
| if(POLICY CMP0990) |
| cmake_policy(SET CMP0990 NEW) |
| endif() |
| |
| .. note:: |
| |
| A policy should almost never be set to ``OLD``, except to silence |
| warnings in an otherwise frozen or stable codebase, or temporarily |
| as part of a larger migration path. |
| |
| * If a policy is set to ``OLD`` by a project, CMake versions released |
| at least |POLICY_OLD_DELAY_WARNING| after the version that introduced |
| a policy may issue a warning that the policy's ``OLD`` behavior will |
| be removed from a future version of CMake. |
| |
| * If a policy is not set to ``NEW`` by a project, CMake versions released |
| at least |POLICY_OLD_DELAY_ERROR| after the version that introduced a |
| policy, and whose major version number is higher, may issue an error |
| that the policy's ``OLD`` behavior has been removed. |
| |
| .. |POLICY_OLD_DELAY_WARNING| replace:: 2 years |
| .. |POLICY_OLD_DELAY_ERROR| replace:: 6 years |
