I think it's better to move this 'let' inside the phase: ...

There is no point in the first 2 'zero?' calls as their returning
values will be lost, rather:

  (and (zero? (system* "cmake" ".."))
       (zero? (system* "cmake" "--build" "." "--config" "Release"))
       (zero? (system* "./dtest" "--runall")))

As for me, the above lines (in synopsis and description) are too long, I
would stay inside 72-78 columns.

Otherwise, the patch looks good to me, so if Leo or other people don't
have comments, I think it can be committed.
