Install
Official installation doc: https://onnxruntime.ai/docs/install/.
One thing to note is that the so-called pre-built mobile packages
contain only a subset of the operators, while the pre-built full packages
contain all the operators.
See https://onnxruntime.ai/docs/build/custom.html for a custom build.
See https://onnxruntime.ai/docs/build/inferencing.html for building for inferencing.
