#井好表示注释
CMAKE_MINIMUM_REQUIRED( VERSION 3.5 ) #设定最小版本号
PROJECT(openglTest)                       #设定工程名

SET(CMAKE_CXX_COMPILER "g++")         #设置编译器（可选的有gcc，g++）

# 设置用debug还是release模式。debug允许断点，而release更快
#set( CMAKE_BUILD_TYPE Debug )
set( CMAKE_BUILD_TYPE Release )

# 设置编译选项
# 允许c++11标准、O3优化、多线程。match选项可避免一些cpu上的问题
