Failling in building sample from TLT-DEEPSTREAM

• Hardware Platform (Jetson / GPU): Jetson AGX XAVIER
• DeepStream Version: 5.0
• JetPack Version (valid for Jetson only)
• TensorRT Version:7.1.0
• NVIDIA GPU Driver Version (valid for GPU only)
Jetpack version: # R32 (release), REVISION: 4.2, GCID: 20074772, BOARD: t186ref, EABI: aarch64, DATE: Thu Apr 9 01:26:40 UTC 2020

I was running the sample in this git with the command:
./deepstream-custom -c pgie_frcnn_tlt_config.txt -i $DS_SRC_PATH/samples/streams/sample_720p.h264

I got the error like this:
(deepstream-custom:11692): GStreamer-WARNING **: 16:22:54.001: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/deepstream/libnvdsgst_infer.so': libnvinfer_plugin.so.7: cannot open shared object file: No such file or directory One element could not be created. Exiting.
How can I solve that? I checked the folder /usr/lib/aarch64-linux-gnu/gstreamer-1.0/deepstream/ and libnvinfer_plugin.so.7 is not there. Even if I sudo cp ... manually to the directory, it stil shows No such file or directory .

Thanks.
