A word of comment: Markus uses a slightly more advanced feature of
ocamlbuild, which is the ability to set compilation tags not in the
ocamlbuild invocation command, as you've been using, but in a dedicated
"_tags" file in the repository:

https://bitbucket.org/mmottl/ocaml-playground/src/65d3ec500ac36683e18d0b84dbf98115f82ea8af/lacaml_test/_tags

You can see the line "true: package(lacaml)", which means that all
compilation commands needed to compile whatever target is required
(test.native, test.docdir/index.html...) will use the lacaml ocamlfind
package (this only works if ocamlbuild is invoked with -use-ocamlfind,
which is the case in his Makefile).
