Embedded Coder: Enable recursive builds for subsystems?

Hi,

I currently work on an embedded target and inside this target I want to issue seperate builds for special subsystems. Roughly speaking, I want to grab all my subsystems inside a make_rtw_hook and call rtwbuild for each of these subsystems.

However, Simulink Coder/Embedded Coder don't like recursive builds and calling rtwbuild from within the make_rtw_hook yields an error.

Is there a possibility to implement this? Maybe, the make_rtw_hook just is not the right place to issue the subsystem builds, but whereelse can I trigger them?

Thanks, Fabian
