Thanks to Daniel KO Listas at the ODE mailing list Don't build graphics demos when OpenGL or GLUT is not found CMake will still build the non-graphical HelloWorld demo (output text to console) Fix linker error: ThreadingDemo requires pthreads on UNIX systems Thanks to reptor, see also http://bulletphysics.org/Bullet/phpBB3/posting.php?mode=reply&f=9&t=5748
