Qt CMake and iPhone simulator

[Reghu_Att]

Hello,
I've been trying to develop a simple test app with Qt/QML and using CMake as my build tool (instead of qmake).
When I use CMake to build and run the app for the MacOS environment everything works fine. When I use the same code to build using qmake the app works perfectly under MacOS and iPhone simulator.

So currently I am stuck. Below is my CMakelists.txt:

cmake_minimum_required(VERSION 3.1)

project(TestFirebase1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_MACOSX_BUNDLE ON)

#iPhone simulator settings
set(CMAKE_OSX_SYSROOT /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator12.1.sdk)
#set(CMAKE_OSX_ARCHITECTURES $(ARCHS_STANDARD_32_BIT))


#set(CMAKE_XCODE_EFFECTIVE_PLATFORMS "-iphonesimulator")
#========================

find_package(Qt5 COMPONENTS Core Quick REQUIRED)

set(project_headers
    backend.h)

set(project_sources
    main.cpp
    backend.cpp)

add_executable(${PROJECT_NAME} ${project_headers} ${project_sources} "qml.qrc")
target_compile_definitions(${PROJECT_NAME} PRIVATE $<$<OR:$<CONFIG:Debug>,$<CONFIG:RelWithDebInfo>>:QT_QML_DEBUG>)
target_link_libraries(${PROJECT_NAME} PRIVATE Qt5::Core Qt5::Quick)
set_target_properties(${PROJECT_NAME} PROPERTIES
    MACOSX_BUNDLE_BUNDLE_NAME $(PROJECT_NAME))

The code compiles under Xcode. But when it tries to run it produces a "The bundle identifier of the application could not be determined." error.

Is there something that I need to add? Is there a simple Qt + CMake + iPhone simulator example that I can follow?

Thank you.
