error building stella_vslam on ros

[mgrallos]

Hi I am trying to implement stella_vslam but I got this error after building it on ros using catkin_make. I am using ROS noetic and it did build up until a 100 but still has an error.

Use OpenCV installed by ROS without building OpenCV.

sorry how to do that? so i just have to install OpenCV and not build it?

I already added this line find_package(OpenCV REQUIRED) on my CMakeList.txt but got the same error

This is because you installed a different version of OpenCV in your environment where OpenCV was installed by ROS.

Restart from reinstalling the OS.

All necessary steps for installation can be found at https://github.com/stella-cv/stella_vslam_ros/blob/ros/Dockerfile.
