CCS/LAUNCHXL-CC2640R2: Cloud CCS Compile Error - trying to resolve but need guidance

Tool/software: Code Composer Studio

I have taken one of the TI Driver examples (watchdog) and attempted to modify to include some code to drive a tone buzzer. I thought I had this resolved, but I now get a new error. Note using CCS Desktop is a NON STARTER. I want to find an easy solution for CCS Cloud. I do not understand what "default tool-commands" the message is referring to.

I am using the following code which I found within another project (buzzer.c and buzzer.h). The only line of code I amended was in buzzer.c where I changed the timer reference library

#include <ti/devices/cc26x0/driverlib/timer.h>
