No private citizen can compel the state to prosecute anyone. Your friend's criminal defense attorney needs to be apprised of this evidence. It's too late to re-do the trial, but it may be possible for her to file for post-conviction relief. There are strict deadlines for this, so don't delay.
I always tell people, don't get too excited about 'lies.' It is rarely compelling to tell a court that other people lied. Courts hear that constantly. What you need to do is to present evidence of the truth.
