link error when set BUILD_YOLO_TENSORRT=ON

[MolianWH]

Envs

• TensorRT 7.1.3.4
• Opencv 4.2
• Cuda 10.2

Build code

cmake . .. -DUSE_OCV_BGFG=ON \
-DUSE_OCV_KCF=ON \
-DUSE_OCV_UKF=ON \
-DBUILD_YOLO_LIB=ON \
-DBUILD_YOLO_TENSORRT=ON \
-DBUILD_ASYNC_DETECTOR=ON \
-DBUILD_CARS_COUNTING=ON \
-DOpenCV_DIR=/usr/local/opencv-4.2.0/build  \
-DTensorRT_ROOT=/usr/local/TensorRT-7.1.3.4

And I also need to edite MULTIRARGET-TRACKER/src/Detector/tensorrt_yolo/CMakeLists.txt and add tensorrt path

SET(TensorRT_ROOT /usr/local/TensorRT-7.1.3.4)
SET(TensorRT_LIBRARY /usr/local/TensorRT-7.1.3.4/lib/libnvinfer.so.7) 
SET(TensorRT_INCLUDE_DIRS /usr/local/TensorRT-7.1.3.4/include)

Errors

Then make it and returns errors:

[ 97%] Linking CXX executable ../MultitargetTracker
../libyolo_rt_lib.so: undefined reference to `createInferRuntime_INTERNAL'
../libyolo_rt_lib.so: undefined reference to `getPluginRegistry'

Other info

If I build with BUILD_YOLO_TENSORRT=OFF, it is successful. But when I run with ./MultitargetTracker ../data/atrium.avi -e=1 -o=../data/atrium_motion1.avi, there is no tarcking output (play origin video and output command about track is 0)

Oh, error in CMakeLists.txt. As fast decision you can try: -DTensorRT_ROOT=/usr/local/TensorRT-7.1.3.4/*.so

@Nuzhny007 Thanks for your patient answer. I reinstalled TensorRT and tried many times, and it built successfully.
