Building 0.11.0 release from source targeting `x86_64-windows-msvc` fails with `uuid` library not found error

[Prcuvu]

Zig Version

0.11.0

Steps to Reproduce and Observed Behavior

1. Build LLVM, LLD and Clang with MSVC
2. Configure Zig with ZIG_HOST_TARGET_TRIPLE=x86_64-windows-msvc and ZIG_TARGET_TRIPLE=x86_64-windows-msvc
3. Build Zig

Observed error log:

It seems that Zig compiler frontend tries to find external system library uuid (a static library under Windows SDK library path). Are we supposed to include Windows SDK library path in lib_dirs to make it happy?

By the way, how does LLD resolve uuid? Do we really need Windows SDK library path?

[torque]

Edit: disregard this comment, the issue I described appears to be a case-sensitivity problem, which I thought I had tested but apparently did not test very well. While the Windows documentation seems to show the library is named Ws2_32.dll, it appears the mingw libc cross-compilation build is producing ws2_32.(lib|def). Since both the Windows and macOS filesystems are case-insensitive by default, it makes sense that Linux trips over the case mismatch while they do not.

Double Triple edit: actually, actually, on macOS, it will produce Ws2_32.def if build.zig tries to link Ws2_32 and it will produce ws2_32.def if build.zig tries to link ws2_32, so there is clearly some different behavior going on between macOS and Linux build hosts here.

---

I have run into this issue (or a very similar one). However, zig's behavior appears to also depend on the host system.

In my case, I am using zig build to build some zig code + a C library, so I'm naturally also linking libc, and the project also needs to link Ws2_32 when targeting Windows (here's a permalink to the commit the following tests are against: https://github.com/epicyclic-dev/nats.zig/tree/3ced6db69d6728eaf4c7817a1f5f86fe4d7eb79a).

Using zig 0.11.0 downloaded from https://ziglang.org (note that I am intentionally avoiding reusing the cache because at some point during playing around with this using different versions of zig, I got into a state I can no longer reproduce where the Linux cross-compilation was working with some mingw artifacts that ended up in the global cache).

zig build -Dtarget=x86_64-windows --global-cache-dir (mktemp -d (pwd)/global-cache.XXXXXXXX) --cache-dir (mktemp -d (pwd)/local-cache.XXXXXXXX)

As I mentioned, I got my x86_64-linux computer into a weird frankenstein state running different versions of zig where the cross compilation eventually succeeded somehow against mingw artifacts in the global cache (it would fail when I cleared the global cache), but I cannot seem to reproduce this now. I also tried zig-0.12.0-dev.98+3e228bdf4 from ziglang.org on my linux hosts this evening and I am seeing the same failure that 0.11.0 has.
