Is it possible to get a description of all required libraries with their versions here?

Hi,

I am compiling torch2trt with c++ extension. I can compile torch2trt with no error. However, there is always undefined symbols when I use: ldd -r torch2trt/libtorch2trt.so

I guess it might be caused by mismatch of required libraries. Is it possible to get a description of all required library with their versions here? I think it should be great to put these in the README.

Thanks in advance!
