unable to symlink from .xwin-cache/splat/crt/lib/x86_64/LIBCMT.lib to libcmt.lib #31

macOS by default uses case insensitive filesystem, xwin splat fails with the following error:

Error: failed to splat Microsoft.VC.14.29.16.10.CRT.x64.Desktop.base.vsix

Caused by:
    0: unable to symlink from .xwin-cache/splat/crt/lib/x86_64/LIBCMT.lib to libcmt.lib
    1: File exists (os error 17)

MacOS is not explicitly supported and has no guarantee to work. However, there is a --disable-symlinks on splat to skip creation of symlinks.

Judging from the code in https://github.com/Jake-Shadle/xwin/blob/8b211ab22e5cf540c3d0f08070642f592cbd0c44/src/splat.rs, disable_symlinks doesn't seem to be used actually.

Oops, you're correct.

I'm happy to report xwin works great on macOS, I've made a Cargo subcommand based on xwin: https://github.com/messense/cargo-xwinbuild
