-We only need 2 third party libs: Protobuf and Leveldb while compiling PhxPaxos library(target is libphxpaoxs.a).But we need GLOG and GRPC while compiling other directories. All these third party libs should be prepared and palced in our `third_party` directory before PhxPaxos compilation. You can `git clone` them by adding `--recursive-submodules` on just download and link them.
