[Omake] Passing full target paths to compilers

[Benjamin Pierce]

Since my project involves OCaml files in several directories, I want  
to invoke the OCaml compiler with the full absolute pathname of each  
source .ml file, so that error messages will be printed in a way that  
emacs can interpret, no matter where I do the compilation from.  Is  
there an easy way to achieve this?

(I tried the obvious one -- changing

    OCamlProgram($(RESULT), $(rootname $(SOURCES)))

to

    OCamlProgram($(RESULT), $(absname $(rootname $(SOURCES))))

but this seems to have no effect.)

Thanks,
