title: Issue: No package 'libcrypto' found
body: <p>I saw this issue "No package 'libcrypto' found". The same error I fixed multiple months ago was to follow this solution: <a href="https://github.com/scipr-lab/libsnark/issues/99" rel="noreferrer">https://github.com/scipr-lab/libsnark/issues/99</a> 
  I tried this solution today however it doesn't work anymore. (I also tried"brew install openssl, brew info openssl") No luck. 
  Have you seen this before? Would you help take a look?</p>
