GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT.

example/example6.cpp:281:3: warning: 'glutInit' is deprecated: first deprecated in macOS 10.9 - OpenGL API deprecated. (Define GL_SILENCE_DEPRECATION to silence
these warnings) [-Wdeprecated-declarations]
glutInit(&argc, argv);
GLUI builds on Mac but results in many warnings.
Ideally we can silence these.
