[SUGGESTION/BUG FIX] On macOS arm64 building the sample projects fails unless a line is added to the CMakeLists.txt file

Hello! It's a possibility this was just an issue on my computer, but when I tried to build the sample projects on an M1 MacBook Pro, it failed because it was trying to retrieve x86-64 dylibs. To fix the issue I added the line `set(CMAKE_OSX_ARCHITECTURES "arm64")` to the `CMakeLists.txt` file and it built perfectly! Just wanted to let y'all know. Thanks!
