C++11 and C++14 are such a huge leap that it would be a shame to stick to old C++03, at least for the long time.

You can find a patch file that contains the CMake build system adaptation for AntTweakBar on Wikisend: http://wikisend.com/download/506872/org.patch Besides, it contains additional changes to CMake build system in order to support some other libraries. 1. I added the Qhull library. Currently it is not used at all, but I'm planning to use it in the OpenSG Base library in the near future. Link: http://www.qhull.org/ https://github.com/qhull/qhull/wiki 2. I added the glm and vmath libraries. I do not intend to use them in any OpenSG libraries nor in any example, but here and then I use them in my examples for testing some code fragments. They are used a lot in the OpenGL community and sometimes it is quite useful to have them at hand. If the libraries are not present nothing awful will be happen. I would really appreciate support for these. The changes are really minimal. Remark 1: AntTweakBar, glm and vmath only show up in the Simple examples targets. Remark 2: I'm not that proficient in the OpenSG CMake build system that I can testimony that the changes are correct for every platform. I only work on the Microsoft Windows platform and do not know the rules for Linux, OSX, etc. On my Windows platform everythink is working fine, so. I hope that OpenSG can support these four libraries in the way I do need them.
