pybuild and setup.py in unusual place

[PICCA Frederic-Emmanuel <frederic-emmanuel.picca@synchrotron-soleil.fr>]

Hello, I have a packahe where the setup.py is not located at the root of the directory.

So I need to do 

override_dh_auto_XXX:
    dh_auto_XXX -- -d <dpath>

Is there a export somthing whcih allows to says where is the setup.py to deal with ?

thanks

Frederic
