[Omake] Compiling files in different directories

[Christopher L Conway]

Do you have an OMakefile in the camlp4 directory? This is required to
make camlp4 part of the project, even though, in this simple case, you
don't need an explicit rule to compile logic.ml. See "Rule Scoping" in
the manual:
file:///home/chris/tools/omake-0.9.8.1/doc/html/omake-doc.html#htoc86

Here's a configuration that worked for me.

Regards,
Chris

OMakefile:

BYTE_ENABLED = true
NATIVE_ENABLED = true

.SUBDIRS: camlp4 resolv

.PHONY: clean

clean:
    rm $(filter-proper-targets $(ls R, .))

camlp4/OMakefile:
# Note: this file can even be empty, so long as it exists.
println(camlp4)

resolv/OMakefile:
FILES = ../camlp4/logic resolv
OCAMLINCLUDES = ../camlp4
PROGRAM = test
OCamlProgram($(PROGRAM), $(FILES))
.DEFAULT: $(PROGRAM).run $(PROGRAM).opt

$ omake --verbose
