------- | |
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. | |
