The code cannot be configured using cmake

从一个全新的构建目录运行 cmake -DCLANG_TIDY=ON .. 以重现失败，然后检查 boost/config/detail/select_stdlib_config.hpp 以及 libs/program_options/src 下失败的源文件。检查日志中显示的编译器和目标配置；当 CMake 配置完成，并且 make -j 8 可以在不再出现缺少 cstddef 的错误的情况下继续执行时，即表示完成。

Summary

Issuing the following command

mkdir build && cd build
cmake -DCLANG_TIDY=ON ..

the configuration fails

Expected behavior

The code should be configured for further compilation, using (for instance) make -j 8

Actual behavior

Configuration fails with errors

No response

Version

git tag returns v0.137 as the latest tag; this is the latest version available on GitHub, downloaded through git clone. The os is linux ubuntu 25.10 running on a virtual machine on a MacBook Pro M4 Max, clang v20.1.8. The boost library (latest version) is already installed but the hunter package manager downloads it again and fails configuring the code.
