It turns out there different versions of the FindPthreads macro lying around :-(. I was refering to this http://www.vtk.org/Bug/file_download.php?file_id=2282&type=bug version, which can be found here http://www.vtk.org/Bug/view.php?id=9074 Best regards, Marcel Loose. _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
