Looks ok. Maybe we could also name the specific Linux distros that need this change to the OSG script - i.e. Debian, ... Of course the optimal solution would be to check how the correct lib directory can be detected automatically (I'm sure there has to be a way to do that). We could then adapt the CMake script and submit a patch to OSG, which would solve the root issue - so we won't need this hack for ever. Another option with minimum effort: post to the OSG-devel list, that there is this issue with Debian - and see what people come up with. | Looks ok.

Yo Thorsten, stumbled on some cmake bugtracker: http://public.kitware.com/Bug/view.php?id=11964 But since I am not a developer, nor am I familiar with cmake, I don't completely understand what they are saying or what exactly the solution is. But it seems as there is a solution for cmake 2.8.5 (which is even available for Debian Stable via backports). hth | |||
