Dependencies & generated headers

Say a source file a.cpp has

#incude "a_parser.h"

and "a_parser.h" is generated by some build action and placed into build 
dir. We need two things to make it
work
1. Add the directory where a_parser.h is placed to the include path when 
compiling a.cpp
2. Make sure a.cpp depends on "a_parser.h". This can be quite simply 
accomplished if the dependency scanner
will check is there's intermediate file called "a_parser.h" in the 
dependency graph for the given main target.
There's a question:

exe a : a.cpp ;
exe b : b.cpp a.whl ;

Here, a_parser.h will be generated when constructing main target b, and 
we can't reliable set a dependency from
a.cpp to a_parser.h. I think this is not a big problem.

Are there any objections to the above ideas?
