编译VDO-SLAM报错：...This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

报错现象：

#error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

解决办法：

在依赖项g2o的CMakeLists.txt文件中指定c++编译器，如下

set(CMAKE_CXX_FLAGS "-std=c++11")
