fatal error: include/System.h: 没有那个文件或目录

[ltf1001]

Hello, thank you to the author for such an outstanding job, he is truly amazing. But when I'm reproducing your project.
At this step:
cd ~/catkin_ws/src/orb_slam3_ros_wrapper/
nano CMakeLists.txt

Change this to your installation of ORB-SLAM3. Default is ~/

set(ORB_SLAM3_DIR
$ENV{HOME}/ORB_SLAM3
)
Build the package normally.
cd ~/catkin_ws/
catkin build
Something went wrong.

The cmake.list I set is:# Change this to your installation of ORB-SLAM3. Default is ~/
set(/home/oem/ORB_SLAM3
).
How should I solve this problem.

It seems there was a formatting issue in your modified CMakeLists.txt. The correct way to set the ORB_SLAM3_DIR variable should be:

```cmake
set(ORB_SLAM3_DIR /home/oem/ORB_SLAM3)
```

However, you generally don't need to change this setting since $ENV{HOME}/ORB_SLAM3 is equivalent to /home/oem/ORB_SLAM3 assuming that your home directory is /home/oem.
