   frankomosh commented at 8:28 am on November 5, 2025: contributor

   Follow-up to #33088.

   Adds cmake -B build -LH documentation to Windows build guides, similar to Unix build documentation.

   Based on the suggestion and example provided by stickies-v in #33088, with minor adjustment to match existing indented code block format in build-windows.md.

   Tested for:

   • WSL Ubuntu with mingw-w64 cross-compilation
   • Windows 11 with Visual Studio 2022 (MSVC)
2. doc: Add cmake help option in Windows build instructions

   Used to display available configuration options, for consistency with recent changes in Unix build docs

    I think it needs to match the format in doc/build-unix.md?

    Not necessarily, in fact, most build instructions have different structure (unify it, if possible, could be the goal of a different PR, as you can see here we need to copy stuff for every platform). My suggestion is not a blocker just that you are adding this line in the middle of the building instructions, and that’s not the case for the other file you are updating. It’s an observation, up to you if you want to leave it that way or not.

    Thanks for clarifying. I think i’ll keep it as-is for now. Yes, unifying structure across build docs as you have suggested is great and can indeed be tackled seperately. Appreciate your feedback!

    (please try to avoid mentions/ @-prefixed github names in PR descriptions as it can cause potential issues, primarily related to notification spam)
