为什么 xutility、xstddef、... 被 clang-tidy 分析，尽管它们没有在构建中使用？

如何解决为什么 xutility、xstddef、... 被 clang-tidy 分析，尽管它们没有在构建中使用？

我正在使用 clang-tidy 整理一个项目，但我从项目中未包含的文件中收到错误消息。这些文件例如：

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include\xstddef
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.28.29333\include\xutility

缩短的错误消息如下所示：

…

这是构建环境的详细信息：

• Win 10 64 位
• MinGW
• 海湾合作委员会 8.1.0
• CMake 3.18.4
• clang 11.0.0
• CMake
  • clang-tidy 变量：set(CMAKE_CXX_CLANG_TIDY clang-tidy "-checks=*,-modernize-use-trailing-return-type")
  • 通过 set(CMAKE_CXX_STANDARD 11) 使用 C++11

显然 xstddef 和 xutility 中的某些内容与 C++11 不兼容。但是我没有在我的构建中的任何地方包含这些文件。 clang-tidy 似乎出于某种原因将它们拉进来进行分析。

在使用 MinGW/GCC 的项目中不能正确使用 clang-tidy 吗？
