temporary fix for anyone who doesn't know: add this to your .cargo/config.toml

[env]
ZLIB_VERSION = "1.3"

[ivanitskiy]

updated CI to use zlib v1.3: e629f97

[dekobon]

This should be fixed in: #61

[willnode]

This should be fixed in: #61

I noticed 0.5.0 is not published in any crate. So I add this...

[patch.crates-io]
ngx = { git = "https://github.com/nginxinc/ngx-rust", rev = "b08a9ee7a2bf9518acb1dac22fa3d241023047e5"}

Just helping if anyone stumbles upon this issue
