@caarlos0 Did you get it to build? I saw you starred it and I would love to use it. Not sure why my build fails. 😞

[caarlos0]

@nikitavoloboev yes, brew install cmake and then

RUSTFLAGS="-L/usr/local/Cellar/openssl/1.0.2q/lib" OPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2q/include PKG_CONFIG_PATH=/usr/local/Cellar/openssl/1.0.2q/lib/pkgconfig cargo release

check the version in /usr/local/Cellar/openssl/, they may be different on your machine...

I'm a happy macOS user too. :)

When using Homebrew, brew --prefix openssl is convenient to ensure that you always have the right path across updating versions. For example, in my .zshenv I have:

export OPENSSL_PREFIX=`brew --prefix openssl`
export PKG_CONFIG_PATH=$OPENSSL_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH
export OPENSSL_INCLUDE_DIR=$OPENSSL_PREFIX/include

and then use RUSTFLAGS="-L$OPENSSL_PREFIX/lib" cargo build --release
