I am trying to install the mysql2 gem.
I am using Ruby version 2.7.6 installed using rbenv with the following environment variables set:
export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"
export LIBRARY_PATH="$LIBRARY_PATH:/opt/homebrew/opt/openssl@1.1/lib/"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/opt/homebrew/opt/openssl@1.1"
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:"/opt/homebrew/opt/openssl@1.1/lib/pkgconfig"
I have openssl 1.1 installed
running the following command:
gem install mysql2 -v '0.5.4' -- --with-opt-dir=$(brew --prefix openssl@1.1) --with-ldflags=-L$(brew --prefix zstd)/lib
brings on this error that seems to indicate zlib cannot be found:

Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

Tried running:
gem install mysql2 -v '0.5.4' -- --with-opt-dir=$(brew --prefix openssl@1.1) --with-ldflags=-L$(brew --prefix zstd)/lib
After installing all known dependencies using homebrew. Also tried:
bundle config build.mysql2 --with-opt-dir=$(brew --prefix openssl@1.1)
bundle install
I have run brew install zstd, gcc and zlib so I should have all the dependencies I need yet I cannot get past this error. I have tried many other things as well but cannot find much information on this error.
Any help would really be appreciated!
