How to get NormalizedLandmarkList of facemesh with C++ interface?

[yonger001]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

None

OS Platform and Distribution

ubuntu20.04

MediaPipe Tasks SDK version

master

Task name (e.g. Image classification, Gesture recognition etc.)

facemesh

Programming Language and version (e.g. C++, Python, Java)

C++

Describe the actual behavior

Cannot find the "mediapipe/framework/formats/landmark.pb.h"?

Describe the expected behaviour

get the NormalizedLandmarkList with demo_run_graph_main.cc

Referring to historical issues, I have built the above face landmark extraction process, but the landmarks_to_render_data_calculator.pb.h and landmark.pb.h files cannot be found under the master project?
