title: Xcode embedding second project, linking error
body: <p>I have a project that uses (or would like to) the route-me (alpstein fork). I have followed  the installations interaction with some limited success. </p>
  
  <p>I have dragged "MapView.xcodeproj" in to my project, I have added mapview.lib, to "target dependancies" and "link binaries with libraries".</p>
  
  <p>if I go to my MapViewController, i can write all my code and I get no errors when importing RMmapView.h. So the compiler is seeing the imported library, however when i build the application I get this error</p>

  <p>I am truly at a loss as to why this is happening, my Research on s/o has drawn a blank so any information or pointers would be appreciated.</p>
