# This DLL can be compiled on Linux using `clang` as a cross-compiler.
# This roughly follows the approach outlined at https://jake-shadle.github.io/xwin/#how.
#
# Install `clang` and `lld` on your distro. We use the MSVC-compatible flavors `clang-cl` and `lld-link` for compilation.
#
# Download and extract the `xwin` downloader: https://github.com/Jake-Shadle/xwin/releases
#
# Use `xwin` to download MSVC header and lib files for 32-bit:
#
#   ./xwin-0.5.0-x86_64-unknown-linux-musl/xwin --accept-license --arch x86 splat --output ./vendor/xwin
#
# Download the header library WIL from https://github.com/microsoft/wil/releases
# and extract it to `./vendor/wil`.
# 7zip is able to extract .nupkg archives.
#
# Run `make` to compile the DLL using the below commands.
