Hi all,

I have an simple OSG application that I'm trying to port to a small 
mobile device (Gumstix), and I'm trying to cross-compile a small subset 
of the OSG library. I don't have OpenGL or X11 available on the device, 
but I don't need that, because I'm only using OSG for basic scene graph 
organization and 3D geometry.

*** I don't need to create windows or render anything ***

So my questions are:

- First, is this possible?
- Has anyone built a subset of OSG and could provide me with a template 
for doing so?
- Does anyone have a basic makefile (not cmake) that I can modify to 
generate a subset of libosg that doesn't link with libGL, libX11, etc.
- I don't really understand the cmake system, so can anyone point me to 
the place where libosg is built? ... or provide me with some basic info 
about changing compilers and preventing cmake from looking in the 
regular locations (eg, /usr/include, /usr/lib, etc)?

The classes I need are the very basic scene graph management stuff:
- osg::Node
- osg::PositionAttitudeTransform
- osg::Group
- osg::Matrix
- osg::Quat
- osg::Vec3
- etc.

Thanks in advance,
-Mike
