Creating executables of simulink models called from m file

I have a GUI which accepts some values from the user and passes it to the simulink model. The output of the simulation (scope variable) is displayed on the axes of the GUI. Now I would like to convert this whole module into an executable. I use the sim command for calling the simulink model. I have read many similar queries but unfortunately I couldnt find a solid procedure to achieve this. Could someone please help me with this.

I am using MATLAB R2012b , Simulink Coder Version 8.3 , MATLAB Compiler Version 4.18 and I have also installed MCR.

Thanks in advance!
