【CMake】CMakeLists.txt的常用命令

cmake官方文档：Documentation | CMake

这里仅针对C++项目来说，我觉得比较有用的一些命令行

SET

Cmake命令之set介绍 - 简书

set( ... [PARENT_SCOPE]) #设置普通变量
set( ... CACHE   [FORCE]) #设置缓存条目
set(ENV{} []) #设置环境变量

提示：

CACHE缓存条目可以通过CMAKE的GUI界面的add entry按钮来增加。

ENV环境变量可以设置dll文件目录，这个环境变量仅用于当前项目，不影响真实的环境变量

include_directories

设置头文件路径

link_directories

设置lib文件目录

link_libraries

设置lib文件路径（全路径）

add_executable

给待编译项目添加源文件

FILE

文件查找

target_link_libraries

链接lib文件（仅名称）

message

打印输出信息

foreach

遍历字符串

# CMake 最低版本号要求
cmake_minimum_required (VERSION 2.8)

# 设置项目名称
SET(PROJECT_NAME "Demo" CACHE STRING "project's name")

# 项目信息
project (${PROJECT_NAME})

# 添加当前路径下的所以源文件
# 查找指定目录下的所有.cpp与.h文件 并存放到指定变量名SC_FILES中
FILE(GLOB SC_FILES "src/*.c" "src/*.cpp" "include/*.h" "*.cpp" "*.h" )
foreach(tempname ${SC_FILES})
	message(${tempname})# 发送信息
endforeach()


# 默认项目在Release模式下编译
