// To reduce the build dependencies for compiling the dawn.node targets, we do
// not use cmake-js for building, but instead just depend on node_api_headers.
// As the name suggests, node_api_headers contains just the *headers* of Napi,
// and does not provide a library to link against.
// Fortunately node_api_headers provides a list of Napi symbols exported by Node,
// which we can use to produce weak-symbol stubs.
