Please check http://glui.sourceforge.net/.
As it is stated there: "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, relying on GLUT to handle all system-dependent issues, such as window and mouse management."
So, what you should do IMHO is to download the glui-2.35.zip from the site, unpak it in a directory and build the GLUI executables (dll and lib). See instructions in the readme.txt file included in the donwloaded zip.
The next step would be to make sure that additional include directories contain also the path to include in you glui installation and the lib built previously is included in the project you are trying to compile.
Hopefully this will solve your problem.
