- 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...4.2)
- This uses the ``<min>...<max>`` syntax to enable the ``NEW`` behaviors
- of policies introduced in CMake 4.2 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
