Are there macros for ocaml that remove code from executable with some compiler options?

I'm writing code in OCaml where I do some stuff when a verbose flag is on.

if verbose then
  do_stuff ();

When verbose is false then this stuff is not executed. However, I'd like to move the flag to some kind of compiler options and not even execute the if verbose check, much like gcc compiler option -DFLAG and #ifdef FLAG in the code would do in C. How can I achieve this functionality?

It might be possible to do that using a ppx. – Louis Roché Feb 17 '19 at 15:23

there are ppxs for conditional execution. For example https://opam.ocaml.org/packages/ppx_const/ – tbrugere Feb 17 '19 at 21:41
