I'm trying out WebAssembly and trying to "cargo install cargo-generate" and it has the error message:

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 = x86_64-apple-darwin $TARGET = x86_64-apple-darwin openssl-sys = 0.9.48 It looks like you're compiling on macOS, where the system contains a version of OpenSSL 0.9.8. This crate no longer supports OpenSSL 0.9.8. As a consumer of this crate, you can fix this error by using Homebrew to install the `openssl` package, or as a maintainer you can use the openssl-sys 0.7 crate for support with OpenSSL 0.9.8. Unfortunately though the compile cannot continue, so aborting.

I'm using macOS 10.14.6, rustc and cargo are 1.36.0. How can I resolve this problem Thanks!
