问题：

我希望在build项目时，把第三方库生成的hearder加入到我root项目下的include文件夹中，方便vscode clangd进行代码提示和补全，还是说主流的做法是到第三方编译好的目录把头文件都拷贝一下到自己项目中，如果有很多依赖库是不是要拷贝很多次？

[star-hengxing]

库安装目录都是这样的：

- f
  - fmt
    - version
      - hash
        - bin -> .dll/.exe
        - lib -> .lib/.a
        - include -> .h/.hpp

add_packages后会把包 include 目录的绝对路径加在编译 flags 里，这样 clangd 才会找到头文件。

这里可能是包没有正确安装头文件导致的，也有可能 flags 没加上，建议先找下原因。

[goluckycoding]

没错，我的库已经成功安装了，我意思是头文件怎么才能自动添加到到我的项目include中（目前我的include是空的，我想能不能自动添加），导致现在代码智能提示有些问题

[star-hengxing]

你确定你配置好了 clangd 么。

[goluckycoding]

配置好了，我发现问题了，是因为我用xmake构建工程后，需要重启clangd进程才会读取最新的header

也有可能是 compile commands 没更新，手动在 vscode 触发下onUpdateIntellisense
