Hi, I wanted to use the depth_image_to_laserscan packagewith my intel realsense. Therefore I pulled this repo in my catkin_ws/src folder and when I try to catkin_make, it fails when coming to this package, here is the stack: `[ 9%] Built target depthimage_to_laserscan_gencfg [ 18%] Building CXX object depthimage_to_laserscan/CMakeFiles/DepthImageToLaserScan.dir/src/DepthImageToLaserScan.cpp.o [ 36%] Built target rviz_click_to_2d In file included from /home/palojetson/Documents/palobot/catkin_ws/src/depthimage_to_laserscan/include/depthimage_to_laserscan/DepthImageToLaserScan.h:40:0, from /home/palojetson/Documents/palobot/catkin_ws/src/depthimage_to_laserscan/src/DepthImageToLaserScan.cpp:34: /opt/ros/melodic/include/image_geometry/pinhole_camera_model.h:5:10: fatal error: opencv2/core/core.hpp: No such file or directory

Thank you for the help! :D

I had the exact same error and then a series of errors afterward. I resolved this by editing the CMakelists.txt. I uncommented line 4:

find_package(OpenCV REQUIRED)

and I also added

include_directories(${OpenCV_INCLUDE_DIRS})
