gluBuild2DMipmapLevels, where to find it?

Hello, I’m under Windows 2000 trying to use the gluBuild2DMipmapLevels function, but I noticed that it is only included in the GLU 1.3 version. I guess I need to call it using wglGetProcAddress() but I don’t know how to do this. I tried downloading the a new glu.h and glu32.lib and now I compile my code, but it doesnt run (DLL error, it can’t find gluBuild2DMipmapLevels).
Thanks in advance.
