I've managed to figure out how to install the dependancies but have been trying to run the package. After typing in the following:

roslaunch ~/ros/stacks/camera_umd/uvc_camera/launch/camera_node.launch

i get this error:

Cannot locate installation of package uvc_camera: [rospack] opendir error [No such file or directory] while crawling /home/sinjon/ros_workspace [rospack] opendir error [No such file or directory] while crawling home/sinjon/ros/stacks [rospack] couldn't find package [uvc_camera]. ROS_ROOT[/opt/ros/electric/ros] ROS_PACKAGE_PATH[/home/sinjon/ros_workspace:/opt/ros/electric/stacks:home/sinjon/ros/stacks]

The package is in home/sinjon/ros/stacks/camera_umd/uvc_camera

did i do something wrong?
