[Omake] Dependencies on generated tools

[Jonathan Roewen]

Hi Again,

Yes, I have two problems to be tackled today =)

Well, more a question of best practice/style, etc.

I have a dir: toolchain/ocaml, which builds a custom ocamlc.

Now, I need my entire tree except that subdir to be built using that
ocamlc. So I set OCAMLC to $(file $(ROOT)/toolchain/ocaml/ocamlc), and
OCAMLLINK to that as well in my OMakeroot.

Then, in toolchain/ocaml/OMakefile I redefine those to ocamlc.

The problem: when it comes to building my tree, it doesn't know to
build my custom ocamlc first. So I'm wondering how do I generate this
dependency properly?

Currently, I just add it as a dependency on the main rules in the root
OMakefile, but I'm pretty sure that if I were in a subdir, trying to
rebuild part of the tree, this trick would fail.

So, is there a nice way to do this more smartly?

Not a big issue -- just would like all the dependencies to be as
accurate as possible =)
