VSCode CMake Ninja环境搭建

VSCode 插件安装

CMake 安装 Download CMake

将cmake bin目录设置在系统环境变量PATH中

Ninja 安装 Releases · ninja-build/ninja (github.com)

将ninja.exe放入cmake的bin目录

CMake插件设置

1. windows平台将生成器改为Ninja，如果不改为Ninja，使用msvc无法导出compile_commands.json

   

2. 勾选 启用导出compile_commands.json, 否则clangd无法分析代码

   

C++ 插件设置

1. 禁用C++ 插件的代码提示 Intelli Sense Engine，使用clangd的代码提示

   

Ninja MSVC编译问题

1. Q: 延迟加载DLL，无法解析的外部符号 __delayLoadHelper2

   A: 需要链接delayimp库，例如 target_link_libraries(xxx PRIVATE delayimp)

Ninja 使用VS2022，并且想使用VS2017工具集

使用CMakePresets.json

                "Clang"
            ]
        }
    ]

通过 toolset 指定 v141工具集

"toolset": {
                "strategy": "external",
                "value": "v141,host=x64"
            },
