AUTOGEN_ORIGIN_DEPENDS¶
New in version 3.14.
Switch for forwarding origin target dependencies to the corresponding
_autogen target.
Targets which have their AUTOMOC or 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.  add_dependencies().  Instead the
AUTOGEN_ORIGIN_DEPENDS target property decides whether the origin
target dependencies should be forwarded to the _autogen target or not.
By default AUTOGEN_ORIGIN_DEPENDS is initialized from
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 - AUTOGEN_ORIGIN_DEPENDS)
- additional user defined dependencies from - AUTOGEN_TARGET_DEPENDS
See the cmake-qt(7) manual for more information on using CMake
with Qt.
Note¶
Disabling AUTOGEN_ORIGIN_DEPENDS is useful to avoid building of
origin target dependencies when building the _autogen target only.
This is especially interesting when a
global autogen target is enabled.
When the _autogen target doesn't require all the origin target's
dependencies, and AUTOGEN_ORIGIN_DEPENDS is disabled, it might be
necessary to extend AUTOGEN_TARGET_DEPENDS to add missing
dependencies.
