| AUTOGEN_ORIGIN_DEPENDS |
| ---------------------- |
| |
| Switch for forwarding origin target dependencies to the corresponding |
| ``_autogen`` target. |
| |
| Targets which have their :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC` property |
| ``ON`` have a corresponding ``_autogen`` target which generates |
| ``moc`` and ``uic`` files. As this ``_autogen`` target is created at |
| generate-time, it is not possible to define dependencies of it using |
| e.g. :command:`add_dependencies`. Instead the |
| :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS` target property decides whether the origin |
| target dependencies should be forwarded to the ``_autogen`` target or not. |
| |
| By default :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS` is initialized from |
| :variable:`CMAKE_AUTOGEN_ORIGIN_DEPENDS` which is ``ON`` by default. |
| |
| In total the dependencies of the ``_autogen`` target are composed from |
| |
| - forwarded origin target dependencies |
| (enabled by default via :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS`) |
| - additional user defined dependencies from :prop_tgt:`AUTOGEN_TARGET_DEPENDS` |
| |
| See the :manual:`cmake-qt(7)` manual for more information on using CMake |
| with Qt. |
| |
| Note |
| ^^^^ |
| |
| Disabling :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS` is useful to avoid building of |
| origin target dependencies when building the ``_autogen`` target only. |
| This is especially interesting when a |
| :variable:`global autogen target <CMAKE_GLOBAL_AUTOGEN_TARGET>` is enabled. |
| |
| When the ``_autogen`` target doesn't require all the origin target's |
| dependencies, and :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS` is disabled, it might be |
| necessary to extend :prop_tgt:`AUTOGEN_TARGET_DEPENDS` to add missing |
| dependencies. |
