[3dprinter-general] Bug#915267: libpolyclipping FTCBFS: does not pass cross flags to cmake

[Helmut Grohne]

Source: libpolyclipping
Version: 6.4.2-3
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

libpolyclipping fails to cross build from source, because it does not
pass cross flags to cmake. The easiest way of fixing that is using
dh_auto_configure. The attached patch does that and simplifies
debian/rules a little using the --sourcedirectory flag. Please consider
applying the patch.
