The most likely documentation page a project author will read in response to a policy warning is the page for the policy itself. Add to every policy documentation page a note explicitly stating that the OLD behavior is deprecated. Also mention this in the cmake_policy() command documentation that explains how to set a policy to OLD. Suggested-by: Fraser Hutchison <fraser.hutchison@gmail.com>

|
Strict checking for the :command:`break` command.
|
|
|
|
CMake 3.1 and lower allowed calls to the :command:`break` command
|
|
outside of a loop context and also ignored any given arguments.
|
|
This was undefined behavior.
|
|
|
|
The OLD behavior for this policy is to allow :command:`break` to be placed
|
|
outside of loop contexts and ignores any arguments. The NEW behavior for this
|
|
policy is to issue an error if a misplaced break or any arguments are found.
|
|
|
|
This policy was introduced in CMake version 3.2.
|
|
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.
