  1. env: Ubuntu 18.04 ros1.0 melodic

  2. question: I would like to know how catkin_make converts msg files into .h files. And If we don't use the catkin_make, can we compile msg files only with CMakeLists.txt

Thanks.

Ad Q2. You can build your ROS node with messages outside catkin_ws, you can follow steps from this tutorial:
