Header file missing while building Arduino custom Simulink s-function

Hi

I am struggeling building an Arduino custom Simulink s-function.

I want to log data with an arudino Mega board while flying and controlling a drone. Every time I build the code Matlab cant find the *.h files (like SPI.h, SD.h, avr/Arduino.h,...).

Is there an convienient way of grating matlab access to all arudino header and cpp files (just like in the Arudino SDK)?

Thanks

Thomas
