Problem installing urg_node on ros hydro

edit

Hi,

I am getting this error when installing the urg_node drivers for hokuyo on Ubuntu 12.04 ROS hydro.

What I did--

1) I have a catkin_ws workspace with build, src and devel folders 2) cd into src folder 3) git clone from the urg_node github page 4) cd into catkin_ws folder 5) run the command $ catkin_make

The error I got is this

    -- +++ processing catkin package: 'urg_node'
-- ==> add_subdirectory(urg_node)
CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:72 (find_package):
  Could not find a configuration file for package urg_c.

  Set urg_c_DIR to the directory containing a CMake configuration file for
  urg_c.  The file will have one of the following names:

    urg_cConfig.cmake
    urg_c-config.cmake

Call Stack (most recent call first):
  urg_node/CMakeLists.txt:7 (find_package)


-- Using these message generators: gencpp;genlisp;genpy
-- Configuring incomplete, errors occurred!
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed

How to resolve this error. The sensor for which I am trying to install the urg_node is hokuyo UHG-08LX.

Like groovy , is there no sudo apt-get command to install the urg_node laser drivers for Hydro?

Thanks
