This is making the case for what I had to do in the 2.8 days (well also again when NVIDIA could not decide on where to put their.... stuff in the file system and CMake was always one version or so behind) and roll my own CMake cuda support... yes this happened... and it could again. Time to look back into my old svn tree. sweet... kickin it with svn again the good old days.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div></div>
