I want to be able to use exla in a livebook. I want to use the livebook on linux (no problem) and windows.
The question I have is how do I install xla?
From hex/github I know, that I have to install some build tools, compiler, depencies on some older versions…
The package info also states that XLA_BUILD=true has to be set? But where do I set it? How do I make sure, that xla is only compiled on windows and not on linux? I assume have to use xla instead of exla?
I tried:

Mix.install(
  [
    {:nx, "~>0.6.1"},
    {:bumblebee, github: :"elixir-nx/bumblebee"},
    {:explorer,
     git: "https://github.com/elixir-explorer/explorer.git",
     ref: "aef274989ab490b0a392ccd19ec24b286a8cda1c",
     override: true},
    {:kino_vega_lite, "~> 0.1.7"},
    {:httpoison, "~> 1.8"},
    {:xla, "~> 0.5.1", XLA_BUILD: true},
    #{:exla, "~> 0.6.1"},
    {:adbc, "~> 0.1"}
  ],
  config: [
    nx: [default_backend: EXLA.Backend]

  ]
)

With *exla commented out or left in.

When I commented out exla I get the error that nmake is missing. I am pretty sure I installed everything. I installed bazel 6.1.2, I already got python 3.7. I installed mysys2 visual studio build tools 2019 and microsoft viusal C++ 2015-2022 Redistributable X86.

P.S.: Can XLA 0.5.1 do all the things as exla 0.6.1? I assume not.
