Can't think of anything simple right now. But if you specify the header 
include paths via CPPPATH, relative within each SConscript, they should 
automatically get expanded for the variant dirs by prepending the output 
directory to each "-I" option. Like this, your header files should get 
found even when created in "debug"/"release", and you have a clear 
separation between inputs and outputs.
Wouldn't that do?
