[Cook] recursive descent cook problem

[Mike Mayers]

patterns like %1 , %2 and %3 contain knowledge of the directory structure
(like the number of levels deep the source tree go). I was trying to avoid
that (I dont know or care how deep the source tree will go, thats why i use
collect and find to find my sources).

unless of course I misread the documentation of %1 %2 and %3. ;>

oh wait, maybe I spoke too soon,

how does a pattern like %%0%2.c or %%0%3.c expand (will these work with a
directory tree of arbitrary depth)?

I use patterns like:
%1/obj/%2.o : [match_mask %%0%2.c [project_files]]

or even (to have multiple compilers)
%1/obj/%2/%3.o : [match_mask %%0%3.c [project_files]]

And for binaries 
%1/bin/%2/%3 : [addprefix %1/obj/%2/ [%3_objs]]

You define you architectures (platforms), compiler, and products:
architecture_list = a1 a2 a3;
products = p1 p2 p3;
compiler = gcc;

Then your targets are:
programs = ;
  loop local thisarch = [architecture_list]
  {
      programs += [addprefix [thisarch]/bin/[compiler]/ [products]];
  }

And cook will automatically figure out which objects it needs to build and
will do so using the .o recipe.
