Reading doc folder on Windows

I have a copy of the zip I built with CMake for Visual Studio 2022. How is the documentation read on Windows 11? Do I have to build the documentation maybe with oxygen?

Yes, the documentation is built with Doxygen. If you have Doxygen installed then Cmake should pick this up during generation, though I’ve not done this on Windows (though I have used WSL to generate the docs which worked well).
