Put your own value in place of <CM_PROJECT> (CarMaker project folder. All writes are confined to it). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: CM_MODEL (Simulink model that cm_session_start opens (name on the MATLAB path, or a file)), CM_MATLAB_SESSION (Name under which MATLAB shares its engine), CM_POPUP_TIMEOUT (Seconds after which CarMaker GUI pop-ups answer themselves with their default choice. Not set: they wait for a click), CM_ENABLE (Optional tools, comma separated: tcl (raw Tcl in the GUI), experimental (Simulink structure edits)), CM_DISABLE (Tool groups to switch off, comma separated: standalone, study, matlab).
