Could not load library dlopen error: libtensorrt_yolox_gpu_preprocess.so

When I use the autoware.universe/perception/tensorrt_yolox node, I encounter an error. I launch it using a launch file.

lhc@lhc-pop-os:~/autoware/install/tensorrt_yolox/share/tensorrt_yolox/launch$ ros2 launch yolox_tiny.launch.xml

I had the same issue, the lib file is not installed in the install folder. I have copied manually:

cp build/autoware_tensorrt_yolox/libautoware_tensorrt_yolox_gpu_preprocess.so install/autoware_tensorrt_yolox/lib/libautoware_tensorrt_yolox_gpu_preprocess.so
