Windows Bundlex Compilation VSCode Toolchain Issue

[druyang]

I ran into this issue when installing on Windows w/ Elixir 1.17.2:

The following arguments were given to IO.chardata_to_string/1:

    # 1
    false

Attempted function clauses (showing 2 out of 2):

    def chardata_to_string(string) when is_binary(string)
    def chardata_to_string(list) when is_list(list)

(elixir 1.17.2) IO.chardata_to_string/1
(elixir 1.17.2) lib/file.ex:246: File.exists?/2
(bundlex 1.5.4) lib/bundlex/toolchain/visual_studio.ex:102: Bundlex.Toolchain.VisualStudio.run_vcvarsall/1
(bundlex 1.5.4) lib/bundlex/toolchain/visual_studio.ex:26: Bundlex.Toolchain.VisualStudio.before_all!/1`

It seems like directory_root is evaluating to :false here:

program_files = System.fetch_env!("ProgramFiles(x86)") |> Path.expand()
directory_root = Path.join([program_files, "Microsoft Visual Studio"])

I think the problem is here: https://github.com/membraneframework/bundlex/blob/8f3b94a8d643c4513d61355be53136cb2ea8fbb4/lib/bundlex/toolchain/visual_studio.ex#L117
there's no proper error thrown, but it seems that the original issue is vswhere.exe missing

I think you're right. I'm new to Elixir, I opened a PR to help provide a warning to the user for that original issue:
