[Vorbis] Compile Encoder_example.c

[Daniel Mikusa]

The output you posted is your linker telling you that it cannot find all of 
the symbols your program requires.  In this case that means it cannot find 
you libvorbis or libvorbisenc libraries.

In your project, go to the Project Menu, Properties.  Under C/C++ -> General, 
set the 'Additional Include Directories' to the path for the Ogg/Vorbis 
header files.  Under Linker -> General set the 'Additional Library 
Directories' to the path for the Ogg/Vorbis library files.  Finally under 
Linker -> Input, put the names of the libraries to include.  I believe for 
that example you will need libogg.lib, libvorbis.lib, and libvorbisenc.lib.

I've not compiled Ogg/Vorbis or the examples on Windows, but that is one of 
the ways to add a library to a project in Visual Studios, which is what you 
need to do.
