Initial support for cmake.preset

[LecrisUT]

Back in #790 I commented that we could support configurePresets if we overwrite the binarydir. It seems to work fine, but I realized we still have an issue to discuss how to deal with the generator. My thinking is that depending on make-fallback value and if preset is present we deffer to the value of preset and let it handle the rest. Although not sure how to detect/handle multi-config then, but wouldn't it build all configs if it wasn't specified explicitly? The documentation of make-fallback is also confusing me a bit.

PS: it took me way too long to figure out nox -t gen was a thing 🤦

I don't think I am handling this part correctly. Generally it should not be tied to the auto-cmake version, but not sure where to feed it to override potential values set by the user. Or we just fail it at builder.cmake?

Windows disapproves, but empty generator is only available in version 3. Not sure if I can bump it and satisfy the other builders. What generator value is available on windows?

scikit-build-core installs ninja via pip anyway, doesn't it? It should be ok to set Ninja on all platforms unconditionally.

[LecrisUT]

Windows is the black sheep here, and there is some logic on scikit-build-core around it. Don't remember the details though. There is also the logic around make-fallback option which confused me a bunch when I first attempted this

This would be really useful as I could replace my [cmake.define] table with a {wheel_tag} preset. I'd like to help. What's the blocker here?

I need to rebase this and run the CI again. Iirc the issue was something to do with windows even when we overwrote the generator. I will not have a pc to work for about 1 week, but could you try a simple rebase and opening a PR in your fork to check the failure again?

Got to rebasing this, and here is the main issue that we encounter in this PR

I believe that we are trying to pass the msvc generator here for which we also pass --config flags, but CMake is then failing when trying to run with the preset generator even though we are overwriting it. Or could be an even simpler issue. I don't have a windows machine to live-test this though, so best I could do is print-debug this
