import Simulink code into code composer studio

I to all, I have a simulink model with an S-Function Builder (include header files and some code). I was able to generate the C dode using Simulink coder (it generate the wrapper.c - tlc - c files).

What I want now is to import this file into CCS but when I tried to compile using CCS i got the error shown bellow. How can I solve this?:

#error directive: Must define one of RT, NRT, MATLAB_MEX_FILE, SL_INTERNAL, or FIPXT_SHARED_MODULE	.ccsproject	/Matlab_simulink_project	line 316, external location: /home/gaston/.local/MATLAB/R2020a/simulink/include/simstruc_compcond.h	C/C++ Problem
