Install OpenBLAS and protobuf library through system package manager. Or you can compile OpenBLAS and protobuf by yourself.
$ sudo apt install libopenblas-dev libprotobuf-dev protobuf-compiler
$ ./generatepb.sh
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make -j4
If you don't use Ubuntu, then you may need to install OpenBLAS and protobuf through your system package manager if any.
