I usually solve this via file variables. Usually you call this make
command when editin specific files. Let the files end with

  ;;; Local Variables: ***
  ;;; compile-command: "cd /work/smithr/sandbox/B-IC-6-2/smarts/clsapi; gmake BV=SUFFIX=V65" ***
  ;;; End: ***

and M-x compile provides you with the wanted default.
