In order to deploy the package locally, first deploy my variation of the portaudio package to your local cache:
git clone https://github.com/dimi309/portaudio-conan
cd portaudio-conan
conan export . --version=19.7.0
Then deploy the small3d package:
git clone https://github.com/dimi309/small3d-conan
cd small3d-conan
conan export . --version=1.8016 (or master)
You can then use small3d as conan requirement small3d/1.8016 or small3d/master
