Sorry, my first mail is unfinished...

Roughly...

$ cat libfoo.clib
foo1.o
bar2.o
...

$ ocamlbuild libfoo.a

> And after having done that, how to tell ocamlbuild that some ocmal-program which is build depends on lib<name>.a.

$ cat _tags
<myocamprog.{byte,native}: use_foo

$ cat myocamlbuild.ml
open Ocamlbuild_plugin;;
open Command;;
dispatch begin function
| After_rules ->
    flag ["ocaml"; "link"; "use_foo"]
            (S[A"-cc"; A"g++"; A"-ccopt"; A"-Lfoo"; A"-custom";
A"-cclib"; A"-Ifoo"]);
    dep ["ocaml"; "link"; "use_foo") ["libfoo.a"]
end;;

Some `flag' declaration might be useful in order to tweak the C/C++ compilation.
