There are two ways to realize what you want right now:

  - Import the CMake build instructions that we have in
    "contrib/buildsystems". It has existed for a rather long time, but
    is not an officially supported way to build Git. It's also lacking a
    couple of features that you can expect from our Makefile, like
    building docs. It may be good enough though.

  - Generate a Visual Studio solution via Meson by installing Meson and
    then running `meson setup --backend=vs2022 build-msvc`. This has
    only landed in Git v2.48 and is thus really new. As such it is still
    marked experimental, but will become an official way to build Git
    and is more feature complete.

I'm aware of an issue with Visual Studio right now though when using it with Meson that keeps it from working -- I'll send a patch series later today to fix that issue, and then it should be a good way to build Git on Windows via MSVC.
