failed to compile custom_communication/TargetAbsPos.h

edit

hello im using the following package for stepper but facing issue while compiling asc_node.ino its says no custom_communication/TargetAbsPos.h: No such file or directory i have done all steps what he have been written but im also confused on this line

To use custom dependencies (e.g. custom messages, services etc.), you have to build these first (catkin build) and then install ros_lib by using the following commands (and not over Arduino IDE):

what is there to catkin build is he mentioning to catkin_make rosserial package in workspace ?
