Error in building hector_navigation

edit

Good day to all.

I have encounter a few errors while building hector_navigation package.

https://github.com/tu-darmstadt-ros-p...

I'm using catkin workspace. During catkin_make, I encountered these errors:

CMake Error at /opt/ros/groovy/share/catkin/cmake/catkinConfig.cmake:75 (find_package):
  Could not find a configuration file for package costmap_2d.

  Set costmap_2d_DIR to the directory containing a CMake configuration file
  for costmap_2d.  The file will have one of the following names:

    costmap_2dConfig.cmake
    costmap_2d-config.cmake

Anybody knows how to correct these? Thanks!
