Didn't seem to help.  Here's what I'm actually working on:

     SFProgram(name, files, sfFiles) =
         LocalOCamlGeneratedFiles($(sfFiles))
         public.OCAMLFLAGS += -thread
         public.OCAML_OTHER_LIBS += unix threads lm gc view_change \
                 mcast_lib reliable_multicast
         public.OCAML_LINK_FLAGS += $(mojavecomm)/lib/gc_clib_impl.a \
                 $(mojavecomm)/lib/mcast_clib.a
         public.OCAMLINCLUDES += $(libmojave) $(mojavecomm)/lib \
                  $(dir ../mcomm-lib)
         public.OCAML_LIBS += $(sfgrouplib)
         files += $(sfFiles)
         return $(OCamlProgram $(name), $(files))
     test-a = $(SFProgram test-a, FakeSpec, test1-a)

OMake fails to build FakeSpec.cmi because the includes aren't all there:
- build test FakeSpec.cmi
+ ocamlopt.opt -warn-error A -I . -c FakeSpec.ml
File "FakeSpec.ml", line 1, characters 0-10:
Unbound module SFLog
