how to build the source code? about torch_cpp

[xmba15]

Hi @doublepoints
I would assume that you are building for a CPU environment. (For GPU env, the steps are quite similar, please explore yourself).

• First of all: install libtorch with this script:
  https://github.com/xmba15/dockerfiles/blob/master/torch_cpp/scripts/install_libtorch.bash

• Install opencv:

sudo apt-get install -y --no-install-recommends \
    libopencv-dev

• Download weights in this release:
  https://github.com/xmba15/torch_cpp/releases/tag/0.0.1

• Build library and apps:

cd /path/to/torch_cpp
make apps

• Test the matching app

./build/examples/match_images_superglue/match_images_superglue_app path/to/superpoint_model.pt path/to/superglue_model.pt ./data/images/VisionCS_0a.png ./data/images/VisionCS_0b.png
