Speex dev - Aug 2009 - Build Speex source code for compact framework

Hello,

I have Speex 1.2rc1 VS2008 source code. I am trying to build the
application but getting build error.

Project : speexenc

Error:	"fatal error C1083"
Description : "Cannot open include file: 'ogg/ogg.h': No such file
or
directory"
File:	 c:\kanchan\speex-1.2rc1\speex-1.2rc1\src\skeleton.c
Line:	10

Error:	"fatal error C1083"

Can you guide me how to build project for Windows Mobile 6.0?

Thanks in advance.
