[Omake] Files in subdirs

[Chris Campbell]

Hi,

How do we use files in subdirectories without using a library?  For
example, in the following tree, the files in tests are organised into
directories according to the corresponding directory in the main src
directory.  This is just a convienance for myself.

Here, unit-tests.ml depends on maths/testMaths.ml, core/testCore.ml.

src/
  OMakefile
  core/
  maths/
  tests/
    OMakefile
    unit-tests.ml
    core/
       testCore.ml
    maths/
       testMaths.ml

I tried the following

src/tests/OMakefile:
  OCAMLINCLUDES+=maths

  TEST_MAIN = unit-tests

  TEST_FILES = testUtils oUExt \
     maths/testMaths $(TEST_MAIN)

  .PHONY: clean
  clean:
	$(CLEAN) $(TEST_MAIN)

  OCamlProgram($(TEST_MAIN), $(TEST_FILES))
  .DEFAULT: $(TEST_MAIN)

This does not work.  I understand why, but am not sure how to go about
fixing it.  I thought of putting an implicit rule in the omakefile to
achieve this, but am wondering if there's an easier way as I'd
probably end up writing a horrible function that caters for whether we
use ocamlopt, ocamlfind, etc using the macros to fill in the flags as
necessary.  Bleh.  It's late so maybe I'm not seeing the obvious
solution (other than putting everything in one directory).


Cheers,
Chris
