[Omake] Dependency Scanning

[Aleksey Nogin]

Jonathan,

Using a custom ocamldep is a fairly standard thing to do. One example 
would be the MetaPRL project. There, the corresponding section of the 
OMakefile looks as follows:


########################################################################
# Directories needing only the standard config
#
.SUBDIRS: clib util

########################################################################
# For the rest of MetaPRL, use our custom scanner.
#
OCAMLDEP_MODULES_ENABLED = false

OCAMLDEP = $(file $(BIN)/ocamldep$(EXE))

OCAMLDEPFLAGS += -omake

.SCANNER: scan-ocaml-%.mli: %.mli $(OCAMLDEP) OCamlGeneratedFilesTarget
.SCANNER: scan-ocaml-%.ml: %.ml $(OCAMLDEP) OCamlGeneratedFilesTarget 
:exists: %.mli

########################################################################


The OCAMLDEP_MODULES_ENABLED is set to false here because the custom 
ocamldep does not support the new "-modules" flag (yet).
