message: Fix setting the cmake target for evg tasks
  Evergreen's expansions syntax means we can't use bash arrays as it eats
  anything using ${. Using a simple variable expansion will result in things
  breaking if a target name has a space in it, but the rest of the script isn't
  space-safe anyway.
