AUTOGEN_ORIGIN_DEPENDS | |
---------------------- | |
.. versionadded:: 3.14 | |
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. |
