[MacOS] don't hardcode z3lib.so and build errors

[nullhook]

if you want this to be cross-platform do not hardcode link_libraries("/usr/lib/libz3.so"). Perhaps add a dep requirement in the readme and if/else OS directive?

i have installed z3 via homebrew and it triggers the build: link_libraries("/opt/homebrew/lib/libz3.dylib")

however, I get lots of build warnings and errors half way.

.../Obfuscation/CryptoUtils.h:68:2: error: "Unknown endianness of the compilation platform, check this header aes_encrypt.h" #error
