Note that some of the puzzles require OpenSSL for the MD5 implementation. On macOS this also requires you to pass an appropariate value for `OPENSSL_ROOT_DIR` to cmake. On x86 this is `-DOPENSSL_ROOT_DIR=/usr/local/opt/openssl` and on AArch64 this is `-DOPENSSL_ROOT_DIR=/opt/homebrew/opt/openssl`. **Note**: Some puzzles require OpenSSL for the MD5 implementation.
