protobuf windows lib链接库生成

1、首先到github下载：protobuf-master、googlemock-master分别解压。

2、然后把googlemock-master文件夹重命名为gmock，然后拷贝到protobuf-master文件夹下面

3、安装cmake，把cmake的cmakelist文件目录指向：protobuf-master/cmake文件夹下面

4、然后选择配置vs2013 x64位，进行编译，如果遇到找不到gtest-all.cc文件，那么修改cmakelist.txt文件夹，把与test相关的配置全部删了，因为我们不需要测试

5、生成代码c++，静态、动态链接问题：md、mt等，那么可以直接删除cmakelist.txt文件来里面的mt的选项

最后的cmakelist.txt文件为：
