qt_add_qml_module's DEPENDENCIES argument accepts targets
This policy was introduced in Qt 6.8. It allows passing targets to
qt_add_qml_module()
DEPENDENCIES
,
IMPORTS
,
OPTIONAL_IMPORTS
and
DEFAULT_IMPORTS
.
Enabling this policy means that the arguments which are passed to the key words can be prefixed with TARGET, and are then treated as a target name.
The
OLD
behavior of this policy is that the "TARGET name" is treated as two URIs, "TARGET" and "name".
The
NEW
behavior of this policy is that
TARGET
is considered a keyword, and the URI is extracted from the target which follows next. It is a hard error if the name following
TARGET
does not name a target, or if that target does not correspond to a QML module.
In both the
NEW
和
OLD
behavior it is possible to specify a module version by appending a slash and the version. See
Declaring module dependencies

Qt 6.8 issues warnings if you pass a URI to
DEPENDENCIES
which coincides with a target name. Use the
qt_policy
command to suppress the warning by explicitly setting the policy to
OLD
or
NEW
.
注意：
The
OLD
behavior of a policy is deprecated, and may be removed in the future.
