- # Returns the absolute path to the specified npm package, searching from the
- # given base directory. This function uses Node's module resolution algorithm
- # searching "node_modules" in the base directory and its ancestors. If no
- # matching package is found, this function returns an empty string.
- #
- # The first argument to this function is the base directory from which to begin
- # searching. The second argument is the name of the npm package.
- #
- # Ex: $(call find-node-module,$(LOCAL_PATH),hermes-engine)
