undefined reference to `lcm_create'

[Joechencc]

Same applies to lcm_publish' andlcm_destory'. Where should I add lcm to Cmake?

Sorry, I fixed that, it is due to my target_link_library

add_executable(pointcloudlistener src/pointcloudlistener.cpp) target_link_libraries(pointcloudlistener ${catkin_LIBRARIES} ${LCM_LIBRARY}) add_dependencies( ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS} )
