Bug#819741: libvtk6-dev: No rule to make target libproj.so / cannot find -lvtkproj4

thanks

Hello Jochen, 

thanks for reporting this. With version -10 I switched to the use of
the system libproj4. Unfortunately, VTK exposes the libproj4 in te
cmake files (which it shouldn't), and also libpcl exposes the vtkprok4
library via its own cmake file. In other words, this change would have
to be handled like an ABI change. Hence I will upload a version that
reverts to the use of the internal version for now to keep ABI
compatibility. 

Best, 
Gert
