opus - Apr 2014 - build opus codec with visual studio 2005

i've downloaded source code from 
<http://www.opus-codec.org/downloads/>
http://www.opus-codec.org/downloads/ but in the tarball there is only one
project for visual studio 2010, it builds well but if i use .lib on visual
studio 2005 they won't work... Anyone knows how to compile with visual
studio 2005?
