We want to use the custom messages defined in different package and we don't understand what will be the "your_program" part in the line we have to add in CMakeList.txt

We have a package named "ros_openpose" which contains a custom message "Frame.msg" that we want to use in another package "trans_ft" of the same workspace (catkin_ws)

ROS Tutorials suggest that we have to add to the following line in CMakeList.txt in trans_ft

add_dependencies(your_program ${catkin_EXPORTED_TARGETS})

Can some one please confirm what will be "your_program" part in our case?

You would need this line only if you want to use that message in a part of ros_openpose. For example if you had a binary called your_program (in that same package) that needs this custom message.

If you want to use it in trans_ft it is sufficient to have ros_openpose as a dependency.

In the CMakeLists.txt of your package trans_ft, is a line that looks something like this find_package(catkin REQUIRED COMPONENTS roscpp std_msgs) and you add there ros_openpose and it looks like: find_package(catkin REQUIRED COMPONENTS roscpp std_msgs ros_openpose)
