Hi,

after changing to cmake, I encounter the following problem when 
compiling gazebo:

Linking CXX executable gazebo

cd /home/steple/gazebo/trunk/server && /usr/local/bin/cmake -E 
cmake_link_script CMakeFiles/gazebo-exec.dir/link.txt --verbose=1
/usr/bin/c++   -O3 -DNDEBUG  -fPIC CMakeFiles/gazebo-exec.dir/main.o  -o 
gazebo -rdynamic -L/home/steple/gazebo/trunk/libgazebo

/usr/local/lib/libgazebo_gui.so -lgazebo -lltdl -lode -lgazebo -lopenal 
/usr/local/lib/libfltk_images.a -lpng -lz -ljpeg

-Wl,-rpath,/home/steple/gazebo/trunk/libgazebo:/usr/local/lib:/home/steple/gazebo/trunk/server/gui

/usr/local/lib/libgazebo_gui.so: undefined reference to `glRasterPos2f'

and a lot more GL and Xinerama related undefined references.
Adding -lGL and -lXinerama fixes this, e.g. executing 'manually'

/usr/bin/c++   -O3 -DNDEBUG  -fPIC CMakeFiles/gazebo-exec.dir/main.o  -o 
gazebo -rdynamic -L/home/steple/gazebo/trunk/libgazebo 
-L/home/steple/gazebo/trunk/server/gui -L/usr/local/lib -lltdl 
-lOgreMain -L/usr/local/lib -lOgreMain -lode -L/usr/local/lib -lode 
-lxml2 -lXft -lopenal -lavformat -lavcodec -lboost_thread-gcc43-mt-1_35 
-lboost_signals-gcc43-mt-1_35 -lfreeimage 
/usr/local/lib/libgazebo_server.so /usr/local/lib/libgazebo_av.so 
/usr/local/lib/libgazebo_gui.so -lgazebo -lltdl -lode -lgazebo -lopenal 
/usr/local/lib/libfltk_images.a -lpng -lz -ljpeg 
/usr/local/lib/libfltk.a /usr/local/lib/libfltk_gl.a 
/usr/local/lib/libfltk_forms.a -lSM -lICE -lX11 -lXext -lm 
-Wl,-rpath,/home/steple/gazebo/trunk/libgazebo:/usr/local/lib:/home/steple/gazebo/trunk/server/gui 
-lGL -lXinerama

and then running make again.
I have never used cmake before, so I have no idea if this problem is 
cmake related or if something is wrong with my system.
