It just so happens that the presence of the DEBIAN directory also fixes my 
use-case (withouth any RPATH): now, dpkg-shlibdeps finds my private libraries. 
However, I notice a strange behaviour from dpkg-shlibdeps:

Note how it works ok when the path to the binary starts with ./ but fails 
otherwise. I narrowed it down to the `relative_to_pkg_root` function in 
Dpkg/Path.pm but I don't understand Perl enoough to go further. Fortunately, the 
way CPackDeb.cmake calls dpkg-shlibdeps has these leading './'.

Bottom line: it works but I don't know how robust it is.
