Cpp Example

[brccabral]

🚀 The feature

The cpp example at vision/examples/cpp/hello_world has dependency of Torch Vision only for cmake, but if we remove TorchVision from CMakeLists.txt and replace it for just Torch and commenting the include in main.cpp, it compiles and runs just fine.
So, TorchVision is not being used in the example.

Motivation, pitch

It would be nice to have an actual TorchVision example in C++. The documentation https://pytorch.org/vision/stable/index.html has only Python references, the example could give a starting point for C++.
