qnx and using pjsip library

hey everyone,
I am trying to use qnx to code a voip application, I have been able to load library called pjsip on my ubuntu machine…the problem arises when I want to integrate this library into the momentics tool that I have download for development. The major problem is that I don’t know how can I add the sip library to the QNX momentics tools. any input will be apperciated.
Thank you
