cmake学习过程记录

基础命令学习

//设置最低版本号

cmake_minimum_required(VERSION 3.5)

//设置项目名称

project (hello_headers)

//递归遍历文件夹src中的cpp文件放到变量SOURCES中

file(GLOB_RECURSE SOURCES  src/*.cpp)

//设置目标exe名称

add_executable(hello_headers ${SOURCES})

//设置包含文件路径，这里设置了两个路径

target_include_directories(hello_headersPRIVATE ${PROJECT_SOURCE_DIR}/includePRIVATE ${PROJECT_SOURCE_DIR}/inc
)

//包含第三方头文件目录

include_directories("D:\\cmake_learn\\MSVC_cmp\\3rdParty\\include")

//链接第三方lib库目录

link_directories("D:\\cmake_learn\\MSVC_cmp\\3rdParty\\lib\\Debug")

//链接第三方库名称

# 添加可执行程序exe名称
