IOS: How to add a Settings.bundle with cmake?

[TheoSys]

For my application I'm developing for iOS, beside other OSs, I need to add a Settings.bundle. It contains the settings menu necessary to configure the app. With qmake it was no problem but now with cmake it seems impossible. At least I found not a single example to adapt.
I found out, that I can add the Settings.bundle this way:

# Settings bundle
set(settings_bundle "ios/Settings.bundle")
file(GLOB_RECURSE settings CONFIGURE_DEPENDS "${CMAKE_CURRENT_SOURCE_DIR}/${settings_bundle}")
target_sources(tpanel PRIVATE ${settings} ${settings_bundle})
set_source_files_properties(${settings} PROPERTIES MACOSX_PACKAGE_LOCATION "Resources/${settings_bundle}")

set_target_properties(tpanel PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER org.qtproject.theosys
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    MACOSX_BUNDLE_INFO_PLIST "${CMAKE_CURRENT_SOURCE_DIR}/ios/Info.plist"
    XCODE_ATTRIBUTE_ASSETCATALOG_COMPILER_APPICON_NAME AppIcon
    QT_IOS_LAUNCH_SCREEN "${bundles}"
)

But then I can not add the individual launch screen any more. The launch screen appears as a blck screen. Beside this, the application does not start any more when I change something in the settings. This makes the app crash immediately when I try to restart it.
Is there another variable available to add the Settings.bundle? Or must I do it completely different?

I must answer my own question. Sometimes I miss the obvious. A Settings.bundle is simply a resource and must be copied to the Resources. Since Apple changed the directory chirarchy in the app bundle, all Resources are files or directories in the root directory. After I realized this, it was simple. Here is a small excerpt of my CMakeLists.txt file:

set(settings_bundle "Settings.bundle")
qt_add_executable(tpanel
    MANUAL_FINALIZATION
    ${PROJECT_SOURCES}
    "${settings_bundle}"
)
target_sources(tpanel PRIVATE "${settings_bundle}")
set_source_files_properties(${settings_bundle} PROPERTIES MACOSX_PACKAGE_LOCATION Resources)

The above code assume, that the Settings.bundle is in the root of the distribution. If this is not the case, then the relative path must be defined as part of the variable settings_bundle.

That's it!
