Compile

1. Init all git module

git submodule update --init --recursive

2. use CMake to compile.

# linux
mkdir build ; cd build ; cmake .. ; make ;

For Linux user,you need to install openssl in your system.
For Windows user,there are openssl header files and precompiled openssl lib in this repository.
You could simply CMake it using Visual Studio.But if the compile has any unexpected error,you might need to change the openssl
dependency yourself.
