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