If this is the full CMakeLists.txt, the problem is simply that you are not building the respective node.

This package actually seems to be a tutorial from Clearpath.

Check the Compiling ... section on how to compile anything. You need to have the two following lines in there:

add_executable(random_driver random_driver.cpp)
target_link_libraries(random_driver ${catkin_LIBRARIES})

And the two lines with set(...) in your CMakeLists.txt don't make sense.

EDIT:

Two possibilities:

1. You don't have costmap_2d installed, do with sudo apt-get install ros-DISTRO-costmap-2d and replace DISTRO with whatever ROS version you are using.
2. You don't configure CMake correctly. Do you have something like find_package(catkin REQUIRED COMPONENTS costmap_2d <otherpackages>) in your CMakeLists.txt? CMakeLists.txt, together with the resepctive include_dirs(${catkin_INCLUDE_DIRS} and target_link_libraries(..) calls? And you need to declare it as aa <build_depend>in thepackage.xml`. in the package.xml.

If this does not help, please update your question with the respective/new CMakeLists.txt content...
