Linker error with PCL recognition module in ros melodic

edit

Hi,

While compiling the pcl object recognition code with ros, following error has occurred.

Tried out the same in PCL standalone, and it compiles successfully.

Platform: Ubuntu 18.04.3 LTS ; ros-melodic; perception_pcl pcl-1.8.1

Error:

Do I need to add any component other than pcl_conversions, pcl_ros, roscpp, sensor_msgs.

Please Help.

Thank you.
