installation find library opencv_aruco

[Tpaddo]

When installing the rtabmap_ros package I get the following error:

CMake Error at /home/user/catkin_ws/devel/share/rtabmap_conversions/cmake/rtabmap_conversionsConfig.cmake:173 (message):
Project ‘rtabmap_demos’ tried to find library ‘opencv_aruco’. The library
is neither a target nor built/installed properly. Did you compile project
‘rtabmap_conversions’? Did you find_package() it before the subdirectory

Before when running this package I on my laptop instead of the orin I didn’t have to install anything else and the installation went well. Do I have to install separate libraries for the orin to make this work? I am running the zed camera with the jetson orin nx.

I think the problem with jetson is that there are 2 opencv installed, one used by ROS (containing only runtime libraries) and another one with dev files. We would have to confirm for latest jetpack though.

For previous jetpacks, here is a post here to fix it:

or the recommended workaround with docker:
