catkin make failling when I will use dynamic reconfigure

edit

I want to use dynamic reconfigure and I changed cmakelist.txt and package.xml like below method

################################################
## Declare ROS dynamic reconfigure parameters ##
################################################

## To declare and build dynamic reconfigure parameters within this
## package, follow these steps:
## * In the file package.xml:
##    * add a build_depend and a run_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
##     * add "dynamic_reconfigure" to
##     find_package(catkin REQUIRED COMPONENTS ...)
##     * uncomment the "generate_dynamic_reconfigure_options" section below
##     and list every .cfg file to be processed

And I do catkin_make but there are error
