How to set <path_to_trt> when installed tensorrt using pip

[PhilipGAQ]

Hi. In the build code below:

mkdir build && cd build
cmake .. -DTENSORRT_ROOT=<path_to_trt> && make -j
# Ensure that you update your LD_LIBRARY_PATH to pick up the location of the newly built library:
export LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH

There is a <path_to_trt>. But I have installed tensorrt using pip, so I don't know how to set <path_to_trt>. Please help me if you can solve the issue!
