Glog的安装与卸载分为两种情况，一种是使用apt，一种是使用源代码。
apt安装与卸载
//安装
sudo apt-get install libgoogle-glog-dev
//卸载
sudo apt-get remove libgoogle-glog-dev
源码安装与卸载
源码安装较为简单，在build目录下，
sudo make install
由于glog并没有提供uninstall命令，所以我的思路是去安装路径下把对应的include和lib都删除掉。
示例
sudo rm -rf /usr/local/include/glog/
sudo rm -rf /usr/local/lib/libglog*
如果不知道glog安装位置，不妨用用locate命令：
~$ locate glog
/usr/local/include/glog
/usr/local/include/glog/config.h
/usr/local/include/glog/log_severity.h
/usr/local/include/glog/logging.h
/usr/local/include/glog/raw_logging.h
/usr/local/include/glog/stl_logging.h
/usr/local/include/glog/vlog_is_on.h
/usr/local/lib/libglog.a
/usr/local/lib/cmake/glog
