How to include an extern library?

[Jia-WeiFang]

Hi,

I want to include the Pytorch C++ library (https://pytorch.org/) in ALXR.
I put the folder downloaded from their official website under the cpp folder (directory: alvr/server/cpp/libtorch),
and add a new line ".include("cpp/libtorch/include")" in build.rs to help the compiler find the pytorch library (libtorch).

However, for some reason, even though the code can find the library correctly, it still fails in the building process with the error message "error: linking with link.exe failed: exit code: 1120".

Does anyone have the experience of including external libraries in ALXR?
How can I solve this problem?

Thanks a lot for your help!!!
