// ONNX_API is a macro that, depends on whether you are building the
// main ONNX library or not, resolves to either ONNX_EXPORT or
// ONNX_IMPORT.
//
// This is used in e.g. ONNX's protobuf files: when building the main library,
// it is defined as ONNX_EXPORT to fix a Windows global-variable-in-dll
// issue, and for anyone dependent on ONNX it will be defined as
// ONNX_IMPORT. ONNX_BUILD_MAIN_LIB can also be set when being built
// statically if ONNX is being linked into a shared library that wants
// to export the ONNX APIs and classes.
//
// More details on Windows dllimport / dllexport can be found at

// This solution is similar to
// https://github.com/pytorch/pytorch/blob/master/caffe2/core/common.h
