I prefer making a DLM. Then life seems simpler, at least to me. However:

' cl' is not recognized as an internal or external command, a program,
executable or a command file.
So your first problem is that cl didn't get executed. You probably need to
specify the entire path or have it on your path.
Having no file generated by "make_dll" led to your other problems
