[TensorFlow] Build TensorFlow v1.12 from the source on Ubuntu 16.04

My previous post: [TensorFlow] How to build your C++ program or application with TensorFlow library using CMake

It is for building TensorFlow from the source based on v1.10. Currently, I want to upgrade it to v1.12 and encounter some problems. 

First, my version of ProtoBuf library on my system is v3.6.1 so that we should align its version in the TensorFlow.
Second, it seems that there are a few issues when building TensorFlow v1.12 that we need to deal with it case by case.


Use git clone and checkout to tag:v1.12.0 for TensorFlow source

git clone --recursive https://github.com/tensorflow/tensorflow
git checkout v1.12.0

In short, I just list the files that I modify as follows:

tensorflow/contrib/cmake/external/protobuf.cmake
tensorflow/contrib/makefile/download_dependencies.sh
tensorflow/tools/ci_build/install/install_proto3.sh
tensorflow/tools/ci_build/protobuf/protobuf_optimized_pip.sh
tensorflow/workspace.bzl

What I modify the content:

git diff tensorflow/contrib/cmake/external/protobuf.cmake \
> tensorflow/contrib/makefile/download_dependencies.sh \
> tensorflow/tools/ci_build/install/install_proto3.sh \
> tensorflow/tools/ci_build/protobuf/protobuf_optimized_pip.sh \
> tensorflow/workspace.bzl

So, we can again do the following steps to build TensorFlow in my previous post:
