how to build the ROS components

[Eren-Yeager]

Like in ORB SLAM2 the ROS components get built in Examples/ROS/ORB_SLAM2 (ros_mono.cc,ros_rgbd.c,ros_stereo.cc) , how can they be built in CORB-SLAM (corbslam_client/Examples/ROS/ORBSLAM2/src ? If they need not to be built then how ROS node can be used ?

After reading the source code, I find the same problem likes yours, what's more, it seems that there are many other problems here.

1. It seems that the author just modifies the source code in corbslam_client/Examples/Stereo/stereo_kitti.cc(only this one), not in corbslam_client/Examples/ROS/ORB_SLAM2/src/ros_stereo.cc, maybe it needs some improvement(It really should be modified in the ros component, I don't understand why it can work as the author says).
2. The hints output is confusing in the modified file, like below, it seems that the author forgets to update it
3. I think the source code can't work, but the details and idea about client-server are worth learning
