写在前面

代码

mkdir cmake_demo

将hello.cpp与CMakeLists.txt放在cmake_demo文件夹下
hello.cpp

#include <iostream>

int main(){
    std::cout<<"hello"<<std::endl;
    return 0;
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

project(Cmake_Hello)

add_executable(hello hello.cpp)

命令行编译与运行

这里使用Release

cd cmake_demo
cmake -DCMAKE_BUILD_TYPE=Release -S ./ -B ./build
cmake --build ./build --config Release --parallel 4
./build/hello

vscode_42">vscode配置编译与调试

vscode 打开cmake_demo目录，configure tasks选择cmake build
在这里插入图片描述
1、生成task.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cmake",
			"label": "CMake: build",
			"command": "build",
			"targets": [
				"all"
			],
			"group": "build",
			"problemMatcher": [],
			"detail": "CMake template build task"
		}
	]
}

ctrl+shift+B可以编译，只不过默认是Debug

2、修改type为shell，可加入上述命令行编译命令以配置CMAKE_BUILD_TYPE等，命令使用分号隔开

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "shell",
			"label": "CMake: build",
			"command": "cmake -DCMAKE_BUILD_TYPE=Debug -S ./ -B ./build;cmake --build ./build --config Debug --parallel 4",
			"group": "build",
			"problemMatcher": [],
			"detail": "CMake template build task"
		}
	]
}

3、上述2也可以分开写
label自己定义，下面的dependsOn对应上就行，ctrl+shift+B之后选择后一个c0mpile_project就行，因为有dependsOn，build_project会一起执行

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "shell",
			"label": "build_project",
			"command": "cmake -DCMAKE_BUILD_TYPE=Debug -S ./ -B ./build",
			"group": "build",
			"problemMatcher": [],
			"detail": "CMake template build task"
		},
		{
			"type": "shell",
			"label": "compile_project",
			"command": "cmake --build ./build --config Debug --parallel 4",
			"dependsOn":["build_project"],
			"group": "build",
			"problemMatcher": [],
			"detail": "CMake template build task"
		},
	]
}
