you must be on windows then ;)

you don't need them, but of course the functionality that is based on
them won't be available without the libs, e.g. without libpng you won't
be able to load png images, without colladadom you won't be able to load
collada scenes...
I haven't tried it, but I think youonly need boost and zlib to build,
but you most likely at least want some of the image format libraries so
that you can load textures.

the support folder contains cmake scripts to build the necessary libs
from source (this ensures they are built with compiler options that
match those used for the OpenSG build). The ReadMe.txt there has (short)
instructions on how to get the sources and how to set up the build.
Distributing binaries for windows is a bit difficult as there are so
many things that have to match (certain compiler switches, the C runtime
you link against, compiler version, 32/64 bit). That means we'd have to
have each library in a number of different variants.
Also there a number of users that use custom options for their build
setup and pre built binaries would not help them, the cmake scripts on
the other hand can simplify their life too, because they can tweak the
script to match their needs.
Cheers,
Carsten
