Marlin difficulties

\B16_32_fullG-112515.ino:44:101: fatal error: U8glib.h: No such file or directory

 #include <U8glib.h> // library for graphics LCD by Oli Kraus (https://code.google.com/p/u8glib/)

I have fixed this part, by adding libraries in the Arduino loader

Using a full graphic display, on a 2560mega
This comes out during compile, and quickly terminates.
I have tried combinations of locations for the files with not joy.
Any help would be appreciated.

In file included from sketch\U8glib.cpp:38:0:
