I figured it out with some off site help.
I was able to compile it by editing the supermodel directory /Src/Input/inputs.cpp
in the input.cpp file you edit the UI Controls line (1st line) for "uiExit"
where it says INPUT_UI, "ESCAPE" you change it to INPUT_COMMON, "NONE"
Then you run the -config-inputs command and map your keys.
The UI Exit should be in the list now to map it.
Now you can exit supermodel from somewhere besides a keyboard.
Here is a youtube link and the guy that helped me. Read the comments and you will get a better understanding
