[Cmake] dependencies

[Franck Bettinger]

Hi Bill,

In fact it's not as easy as that.
The file drawingimpl.cxx include drawingimpl.h and drawingimpl.h includes 
drawing.h
So drawing.h is not in the cmake.depends file, but drawingimpl.h is.
Unfortunately, as there is no make rule for drawingimpl.h, there's no link to 
drawing.h in cmake.depends.

Furthermore, if I include drawing.h in drawingimpl.h, I can only find 
drawing.h in cmake.depends if I use the syntax :
#include <drawing.h>

Other syntaxes like
#include "drawing.h"
or
#include <drawing/drawing.h>
don't work.

In the case I use the first syntax, I have the line : 
drawing.h \
in cmake.depends.

The "make" utility doesn't seem to be able to match that to the full path 
name as used in the rule for creating drawing.h in Makefile (certainly 
because drawing.h is not in the source directory but in the object directory 
because it is a generated file). 
I can change this rule to use only the name of the file, but I would like a 
proper solution with the full pathname as it might be a problem if it's used 
in a library, and also for consistency with the rest of the Makefile. 
Furthermore I don't know if this patchy solution would be crossplatform.

Concerning ADD_DEPENDENCIES, I think it's strange to have to link executable. 
What we would certainly need is the possiblitity of linking generated files. 
And it's the way I've (mis)understood the command.
