# qt_import_plugins

## Synopsis

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

## Description

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

This CMake command was introduced in Qt 5.14.

- `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.

Qt provides plugin types such as `imageformats`, `platforms`, and `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`.

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

This command was introduced in Qt 5.15. You can use qt5_import_plugins in older versions of Qt.

## Examples

     add_executable(myapp main.cpp)
     target_link_libraries(myapp Qt5::Gui Qt5::Sql)
     qt_import_plugins(myapp
         INCLUDE Qt5::QCocoaIntegrationPlugin
         EXCLUDE Qt5::QMinimalIntegrationPlugin
         INCLUDE_BY_TYPE imageformats Qt5::QGifPlugin Qt5::QJpegPlugin
         EXCLUDE_BY_TYPE sqldrivers
     )

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

- The `Qt5::QCocoaIntegrationPlugin` is imported into myapp.
- The `Qt5::QMinimalIntegrationPlugin` plugin is excluded from being automatically imported into myapp.
- The default list of plugins for `imageformats` is overridden to only include Qt5::QGifPlugin and Qt5::QJpegPlugin.
- All `sqldrivers` plugins are excluded from automatic importing.
