VScode中cmake调试

一般的cmake命令行测试方法：

cmake -S . -B build

cmake --build build

./build/cmake_debug

在vscode中使用图形化界面操作的方法

main.cpp

#include <iostream>

int main()
{
    int num_a, num_b;
    num_a = 10;
    num_b = 20;
    std::cout << "num_a = " << num_a << std::endl;
    std::cout << "num_b = " << num_b << std::endl;
    return 0;
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

project(cmake_debug)

add_executable(cmake_debug main.cpp)

按照上述配置完成也可以正常debug
