Compilation doc page is obsolete

[younesbelkada]

Currently the compilation guidelines in https://huggingface.co/docs/bitsandbytes/main/en/compiling are obsolete as the makefile has been deleted due to the cmake refactor. It would be great if one could re-write that documentation page so that it is up-to-date with the current way of compiling bnb from source

Do we need to maintain the install_cuda scripts? It seems they need constant updating with new CUDA versions. Also, the way to specify CUDA version is a lot more standardized with cmake, and we could only refer to this:

https://cliutils.gitlab.io/modern-cmake/chapters/packages/CUDA.html

(Basically, set CMAKE_CUDA_COMPILER to the path to nvcc, version is picked up automagically if I understood the docs correctly)

And then just a link to the CUDA download page:

https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#ubuntu

(Linux users might prefer their distro's method of installing, such as adding the Nvidia apt channels)

Then it's only about, install the CUDA version you want, if you have multiple versions, use -DCMAKE_CUDA_COMPILER=<path to nvcc> -DCUDA_VERSION=<cuda version>. We can probably do away with CUDA_VERSION as it is best left to cmake to figure out

This makes totally sense to me ! Do you want to try your hands on this? Otherwise I can do it and ping you for review

I created #1048, please have a look at what you think
