用KDevelop调试 slam14讲的 3.7显示运动轨迹的程序时提示：

error: #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.

这是缺少对C++11标准的支持，在CMakeLists.txt中的声明CMake工程的语句之后添加：

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

即可。
