qt_import_plugins

Specifies a custom set of plugins to import for a static Qt build.

The command is defined in the 核心 组件对于 Qt6 package, which can be loaded like so:

find_package(Qt6 REQUIRED COMPONENTS Core)

This command was introduced in Qt 5.14.

概要

qt_import_plugins(target
                  [INCLUDE plugin ...]
                  [EXCLUDE plugin ...]
                  [INCLUDE_BY_TYPE plugin_type plugin ...]
                  [EXCLUDE_BY_TYPE plugin_type]
                  [NO_DEFAULT]
)

若 versionless commands are disabled, use qt6_import_plugins() instead. It supports the same set of arguments as this command.

描述

Specifies a custom set of plugins to import. The optional arguments: INCLUDE , EXCLUDE , INCLUDE_BY_TYPE ，和 EXCLUDE_BY_TYPE , can be used more than once.

INCLUDE – can be used to specify a list of plugins to import.
EXCLUDE – can be used to specify a list of plugins to exclude.
INCLUDE_BY_TYPE – can be used to override the list of plugins to import for a certain plugin type.
EXCLUDE_BY_TYPE – can be used to specify a plugin type to exclude; then no plugins of that type are imported.
NO_DEFAULT – prevent the default plugins from being included automatically (for example, the default platform plugin).

Qt provides plugin types such as imageformats , platforms ，和 sqldrivers .

If the command isn't used the target automatically links against a sane set of default plugins, for each Qt module that the target is linked against. For more information, see target_link_libraries .

Each plugin comes with a C++ stub file that automatically initializes the plugin. Consequently, any target that links against a plugin has this C++ file added to its SOURCES .

注意： This command imports plugins from static Qt builds only. On shared builds, it does nothing.

范例

qt_add_executable(myapp main.cpp)
target_link_libraries(myapp Qt::Gui Qt::Sql)
qt_import_plugins(myapp
    INCLUDE Qt::QCocoaIntegrationPlugin
    EXCLUDE Qt::QMinimalIntegrationPlugin
    INCLUDE_BY_TYPE imageformats Qt::QGifPlugin Qt::QJpegPlugin
    EXCLUDE_BY_TYPE sqldrivers
)

In the snippet above, the following occurs with the executable myapp :

The Qt6::QCocoaIntegrationPlugin is imported into myapp.
The Qt6::QMinimalIntegrationPlugin plugin is excluded from being automatically imported into myapp.
The default list of plugins for imageformats is overridden to only include Qt6::QGifPlugin and Qt6::QJpegPlugin.
所有 sqldrivers plugins are excluded from automatic importing.
