I installed the ORB_SLAM3 package, but it can't be detected!!

[Joshua-0922]

Hello, I tried to install orb_slam3_ros, with ubuntu 20.04 ros2 foxy environment.

After install two packages(ORB_SLAM, orbslam3_ros) in home\colcon_ws\src, I successfully build the execution file for ORB_SLAM.

But whenever I've tried to colcon build the orbslam3_ros, there's some error that failed to find the following files. What's the matter??

yoonho@yoonho-950SBE-951SBE:~/colcon_ws$ colcon build --symlink-install --packages-select orbslam3
