    #   About the STATUSQ_SHADOW_BUILD option.
    #
    #   This is an option that defaults to OFF in Debug mode and ON otherwise.
    #   When ON:
    #     - resources are compiled into plugin
    #     - plugin is compiled in the ${CMAKE_BINARY_DIR}/StatusQ
    #   When OFF:
    #     - no resources are compiled, it's expected to use QML/JS sources
    #     - the plugin is compiled in src directory
    #
    #   STATUSQ_SHADOW_BUILD mode is created for sandbox/storybook hot reloading
    #   without copying all qml files to build directory.
    #
    #   It's expected for the app to add ${STATUSQ_MODULE_IMPORT_PATH} to
    #   QQmlApplicationEngine::addImportPath.
