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.

-------

|
|
The target in the ``TARGET`` signature of :command:`add_custom_command`
|
|
must exist and must be defined in the current directory.
|
|
|
|
CMake 2.8.12 and lower silently ignored a custom command created with
|
|
the ``TARGET`` signature of :command:`add_custom_command`
|
|
if the target is unknown or was defined outside the current directory.
|
|
|
|
The ``OLD`` behavior for this policy is to ignore custom commands
|
|
for unknown targets. The ``NEW`` behavior for this policy is to report
|
|
an error if the target referenced in :command:`add_custom_command` is
|
|
unknown or was defined outside the current directory.
