I am trying to build an application using GL User Interface. http://glui.sourceforge.net/ Does anybody know how to get this working under Xcode? ive found this: http://lukecyca.com/2007/02/14/glui-23-framework-for-mac-os-x/ but im not sure how to incorporate the framework into my project. I believe I added it correctly added the framework but it still gives an error on the line #include<GLUI/glui.h> and says there is no such file or directory. Can anybody offer some help? can anyone tell me how to get the GLUI libraries added to my project? Thanks for any help.
