配置工程及引入测试--针对C++

 书写CMakeList同时支持windows、Linux、Mac,将头文件，三方库，源文件，测试代码目录进行分离

使用CMAKE区分Debug版本和Release版本；工程中同时生成动态库和测试用例；动态库方便日后的调用，测试用例用来检查程序的正确性

 

C++这一块使用 googleTest作为测试工具

 

对应的CMakeList如下

cmake_minimum_required(VERSION 3.0)
project(DS)

set(CMAKE_CXX_STANDARD 14)
set(GOOGLETEST_VERSION 1.9.0)

#判断系统环境
if (CMAKE_HOST_WIN32)
    set(win 1)
elseif (CMAKE_HOST_APPLE)
    set(MACOS 1)
elseif (CMAKE_HOST_UNIX)
    set(LINUX 1)
endif ()

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
if(win)
    set(CMAKE_PREFIX_PATH C:\\Qt\\Qt5.14.2\\5.14.2\\msvc2017_64)
