In commit v3.5.0-rc1~8^2~2 (Help: Clarify policy `CMP0040` documentation, 2016-01-28) the documentation was clarified to indicate that the target must be defined in the current directory. Do the same for the text of the policy warning itself. Fixes: #17399

-------

|
|
|
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.
|
|
|
|
This policy was introduced in CMake version 3.0. CMake version
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior.
|
|
Use the :command:`cmake_policy` command to set it to ``OLD`` or
|
|
``NEW`` explicitly.
