@dHofmeister your requirement is related with https://github.com/ZhenshengLee/perception_cupoch/issues/3 https://github.com/ZhenshengLee/perception_cupoch/tree/noetic#cupoch this will help to use cupoch with ros2 and cpp. https://github.com/ros2cuda/cupoch-fat/commit/20d9cb532527724fcc03546826733be4c64f4b95 https://github.com/ros2cuda/cupoch-fat/commit/61aa98cf663a13e548f9b74fd78a86ccd2f3ad9b https://github.com/ros2cuda/cupoch-fat/commit/352f39ab54587e5a0663af8c6e80f4e086cc70f2 these are useful custom changes to make cupoch cpp...
