I managed to successfully compile it on Jetson TX2 following these steps:

1.Build PyTorch from source. python3 setup.py build

2.No need to download LibTorch from the official website, which is the x86_64 build.

3.build the example-cpp using compiled tmp_install directory: cmake -DCMAKE_PREFIX_PATH=/absolute/path/to/pytorch/torch/lib/tmp_install ..

You might be building libtorch with a compiler that is incompatible with the compiler building your final app.

For example, you built libtorch with gcc 4.9.2 and your final app with gcc 5.1, and the C++ ABI between both of them is not the same, so you are seeing linker errors like these
