Defaul MCU project made in QDS contains a deprecated cmake API

When you create a default MCU project in QDS, it contains app_target_default_main in CMakeLists.txt, which seems to have been already deprecated and fails the configuration at Qt Creator. The default CMakeLists.txt generated by QDS should be updated accordingly.

<error>

[cmake] CMake Error at CMakeLists.txt:80 (app_target_default_main):
[cmake]   Unknown CMake command "app_target_default_main". 

The project is attached.
