Hi there, I am trying to build the project but I'm currently running into the following problem when running cmake -DCMAKE_PREFIX_PATH=~/Documents/libtorch/ ..:

-- The CXX compiler identification is AppleClang 10.0.1.10010046

I managed to successfully run the libtorch example before building this project. I'm a newbie to cmake projects and the error above might be something trivial, so I'm asking for help.

Looks like you need to run git submodule update --init --recursive. I forget that step all the time.
