    Description

      When using Ubuntu 20.04, the system's built-in CMake 3.16 is not able to find the Android SDK API directory when trying to build the notifications_list example: 

      Running /usr/bin/cmake -S /home/jannejuntunen/workdir/tqtc-android-automotive/examples/base/notifications_list -B /home/jannejuntunen/workdir/tqtc-android-automotive/examples/base/build-notifications_list-Android_Qt_6_6_0_qt6_build_android_install_Clang_x86_64-Debug in /home/jannejuntunen/workdir/tqtc-android-automotive/examples/base/build-notifications_list-Android_Qt_6_6_0_qt6_build_android_install_Clang_x86_64-Debug.
CMake Error at /usr/share/cmake-3.16/Modules/Platform/Android-Determine.cmake:170 (message):
  Android: The API specified by CMAKE_SYSTEM_VERSION='23' does not exist in
  the NDK.  The directory:
    /home/jannejuntunen/Android/Sdk/ndk/25.1.8937393/platforms/android-23
  does not exist.
Call Stack (most recent call first):
  /usr/share/cmake-3.16/Modules/CMakeDetermineSystem.cmake:129 (include)

      The problem is that the API folder location is not the same as it used to be.

      In my case, the wrong folder path is 

      /home/jannejuntunen/Android/Sdk/ndk/25.1.8937393/platforms/android-23

      Whereas the correct one would be: 

      /home/jannejuntunen/Android/Sdk/platforms/android-23

      Apparently, in NDK r22 the directory structure was changed and this has been taken into account in CMake 3.19 onwards:
      https://gitlab.kitware.com/cmake/cmake/-/issues/21652

      The problem is that Qt's minimum CMake requirement is still 3.16 and this is also used in QtAA sources:

      cmake_minimum_required(VERSION 3.16)

      The problem went away when I selected CMake 3.24 installed by the Qt installer:
