The `windows-gnu` package misses `zlib1__.dll` that is needed by `rust-lld.exe`

Code

I tried this:

1. Checkout https://github.com/enso-org/rust-lib/ (at https://github.com/enso-org/rust-lib/commit/966be60f29c3df60c5d5d5c0c9851628121d371e)
2. Force windows-gnu nightly: rustup override set nightly-2021-05-12-x86_64-pc-windows-gnu
3. Add wasm target: rustup target add wasm32-unknown-unknown
4. Build the package for wasm32-unknown-unknown: cargo build --package enso-macro-utils --target wasm32-unknown-unknown --verbose

Result:

       Fresh unicode-xid v0.2.2
       Fresh proc-macro2 v1.0.26

       Fresh syn v1.0.72

The rustc invokes rust-lld. rust-lld depends on zlib1__.dll that is not present in the distribution. If I add it manually, the issue goes away.
The windows-msvc flavor ships with rust-lld that does not have this dependency.

I have the same issue with "stable" rust 1.52.1 (9bc8c42 2021-05-09) on Windows 10 with a wasm32-unknown-unknown target.

Can you elaborate on how to quick-fix this by adding zlib1__.dll manually?

Where can I get, and where do I put zlib1__.dll?
I only have zlib1.dll from Mingw64, Mingw32, and many other SW packages.
Is it the same?

Btw. what hit me instantly is the move from LLVM 11 to 12. Might that be the issue?

Yes, at least enough so it works for me. Just rename any zlib binary, the library interface has been stable for a very long time, so it should just work. Or, if you are ok with using binaries received from strangers, take this: zlib1__.zip.

When you have zlib1__.dll, you need to make it visible. Either place it in any location visible in PATH environment variable, or place it next to the rust-lld.exe. For me it is located in ~\.rustup\toolchains\nightly-2021-05-12-x86_64-pc-windows-gnu\lib\rustlib\x86_64-pc-windows-gnu\bin. See this if you want in-depth explanation where the Windows looks for the DLLs.
