If you need to have curl-openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/curl-openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find curl-openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/curl-openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/curl-openssl/include"

For pkg-config to find curl-openssl you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/curl-openssl/lib/pkgconfig"
