1. target_link_libraries continuous_clustering ?

# helper functions to publish clustering result to ROS
add_library(continuous_clustering_ros src/ros/ros_utils.cpp)
target_link_libraries(continuous_clustering ${catkin_LIBRARIES}

2. I successfully built the ouster-ros project in catkin_ws, but encountered the following problems when building this project:
