Prefix-relative subdirectory for deploying QML plugins on some target platforms.
This variable is defined by the script named by QT_DEPLOY_SUPPORT . It should only be used as part of deployment during installation or a post-build rule.
This variable was introduced in Qt 6.3.
Projects should use
QT_DEPLOY_QML_DIR
in their deploy scripts to avoid hard-coding a particular directory under which to deploy QML modules.
QT_DEPLOY_QML_DIR
defaults to the value
qml
. To change the value of
QT_DEPLOY_QML_DIR
, set it in the project deployment script before
QT_DEPLOY_SUPPORT
is included.
The
QT_DEPLOY_QML_DIR
path is relative to
QT_DEPLOY_PREFIX
.
This variable is not meaningful when deploying into a macOS app bundle and should not be used for that scenario. Apple's macOS app bundle guidelines require all plugins to be deployed to the
PlugIns
subdirectory of the bundle contents, and all other non-binary files should generally be under the
资源
subdirectory. The different parts of a QML module therefore need to be deployed to different locations within the app bundle.
