Linker error building bot2-vis on Mac OS X Lion

[GoogleCodeExporter]

This applies to rev 442, pulled on 07/09/13.  When attempting to build 
bot2-vis, I encountered the following error(s):

Undefined symbols for architecture x86_64:
  "_XFree", referenced from:
      _bot_gtk_gl_drawing_area_init in gl_drawing_area.c.o
      _bot_gtk_gl_drawing_area_realize in gl_drawing_area.c.o
      _bot_gtk_gl_drawing_area_unrealize in gl_drawing_area.c.o
  "_XGetVisualInfo", referenced from:
      _bot_gtk_gl_drawing_area_realize in gl_drawing_area.c.o
  "_XVisualIDFromVisual", referenced from:
      _bot_gtk_gl_drawing_area_init in gl_drawing_area.c.o
      _bot_gtk_gl_drawing_area_realize in gl_drawing_area.c.o
ld: symbol(s) not found for architecture x86_64

After looking at the build files cmake generated, it looks like the linker was 
not being told to include the X11 library.  To fix, I modified the 
CMakeLists.txt in the bot2-vis root to set a X11_LIBRARIES variable, and then 
modified CMakeLists.txt in src/bot_vis to use this new variable.

A diff against rev 442 is attached.
