I have this in my OMake files:

if $(test -e .git)
  GIT_COMMIT = 'Some "$(shell git rev-parse HEAD)"'
  export
else
  GIT_COMMIT = 'None'
  export

I also define VERSION manually, but ideally I should extract the version
from my opam file.

Given those, I use m4 as follows to generate an About module for most of my
projects.

m4 -D VERSION=$(VERSION) -D GIT_COMMIT=$(GIT_COMMIT) about.ml.m4 > about.ml

$ cat about.ml.m4
(** General information about this project. *)

(** Version: [VERSION] *)
let version = "VERSION"

(** Git commit if known: [GIT_COMMIT] *)
let git_commit = GIT_COMMIT
