Every policy's documentation has a paragraph on what version of CMake introduced it, how to set the policy, and whether CMake warns if the policy is not set. The wording of this paragraph has diverged across policies over time. Factor the paragraph out into a standard advice document included by every policy.

:command:`while` diagnoses condition evaluation errors.
|
|
|
|
CMake 3.23 and below accidentally tolerated errors encountered while
|
|
evaluating the condition passed to the :command:`while` command
|
|
(but not the :command:`if` command). For example, the code
|
|
|
|
.. code-block:: cmake
|
|
|
|
set(paren "(")
|
|
while(${paren})
|
|
endwhile()
|
|
|
|
creates an unbalanced parenthesis during condition evaluation.
|
|
|
|
CMake 3.24 and above prefer to diagnose such errors. This policy
|
|
provides compatibility for projects that have not been updated to
|
|
fix their condition errors.
|
|
|
|
The ``OLD`` behavior for this policy is to ignore errors in
|
|
:command:`while` conditions. The ``NEW`` behavior for this
|
|
policy is to diagnose errors in :command:`while` conditions.
