config.c occurred bugs

[alLiucb]

well,I tested to build it with debug version[I don't know if this approach is correct or not.]
steps are as follows：
1.I deleted the original build folder.
2.command：
①cmake -B build -S . -G "Visual Studio 17 2022" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX="my/path/for/install"
And logs：

CMake Warning:

-- Build files have been written to: G:/00_STU/Cesium-unity-native/cesium-unity-samples/Packages/com.cesium.unity/native~/extern/tidy-html5/build

It seems it's no problem.

②cmake --build . --config Debug
MSBuild version 17.5.1+f6fdcf537 for .NET Framework

I checked line 129 of config.c, but there is nothing，like this：
