After creating these two files in the src folder, we have to edit the package.xml and CMakeLists.txt to build the nodes.
The package.xml file should contain message generation and runtime packages, as we did for ROS service and messages.
We have to include the Boost library in CMakeLists.txt to build these nodes. Also, we have to add the action files that we wrote for this example:
find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs actionlib actionlib_msgs message_generation )
We should pass actionlib, actionlib_msgs, and message_generation in find_package():
## System dependencies are found with CMake's conventions find_package(Boost REQUIRED COMPONENTS system)
We should add Boost as ...
