reqwestをつかったlambad buildをするとopensslのエラーがでてしまった...

+ cargo lambda build --release --arm64
   Compiling openssl-sys v0.9.80
error: failed to run custom build command for `openssl-sys v0.9.80`

Caused by:

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

  $HOST = aarch64-apple-darwin
  $TARGET = aarch64-unknown-linux-gnu
  openssl-sys = 0.9.80

opensslはビルド周りの環境構築に気を使わないとうまくいかないっぽい.
しらべるといろいろ回避方法はあるっぽいのだけど、いったんopensslの依存を抜く感じで対応した.
default-features = false と features = ["rustls-tls"] で対応

$ git diff Cargo.toml
...
-reqwest = { version = "0.11.13", features = ["json"] }
+reqwest = { version = "0.11.13", default-features = false, features = ["json", "rustls-tls"] }
...

他にもrust-musl-builderでdocker経由でビルドするなど方法があるっぽい (試してない)
