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.
