# Okay, we have a problem. GitHub does not like to host files >100MB.
# But libLLVM-<version>.dll easily blasts through that limit.
#
# Ideally, we would use UPX to compress that `.dll`, but there is no
# support for compressing Windows/ARM64 files using UPX (yet).
#
# So let's do the next best thing and `strip` the file. Sadly, we need
# to download the entire (also *large*) `mingw-w64-x86_64-llvm` to get
# `llvm-strip.exe` to perform this job because the already-installed
# `/usr/bin/strip.exe` does not know what to do with Windows/ARM64 files,
# either.
