//if you are using "glew32s.lib" file you may have to add GLEW_STATIC in the

//properties -> c/c++ -> Preprocessor -> Preprocessor Definitions 
//and add GLEW_STATIC.
//or use '#define GLEW_STATIC' before every include of glew.h

//the next part is copied from glew.h
//which is why you have to add GLEW_STATIC in Preprocessor Definitions or define it
//or the code will look for the glew32.dll file
