I am new to ROS, but slowly catching on.  I downloaded a package and ran rosmake, I got a dependency error like the following.  <br><br>[rosbuild] Building package pi_head_tracking_tutorial<br>  Failed to invoke /opt/ros/fuerte/bin/rospack deps-manifests pi_head_tracking_tutorial<br>
  [rospack] Error: package/stack pi_head_tracking_tutorial depends on non-existent package uvc_cam<br>  <br>  <br>  CMake Error at /opt/ros/fuerte/share/ros/core/rosbuild/public.cmake:129 (message):<br><br><br>I then download and run rosmake on uvc_cam2, which builds fine.  I download and build uvc_cam2 in the ros_workspace directory, however after building I still get the error.  after building a package, is there something to do in order to get ROS to recognize it?<br>
