Build issues on Darwin

[seclorum]

The CMakeLists.txt file for this project doesn't seem to like AppleCLang:

$  clang --version
Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin23.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I added a message call to report the value of CMAKE_CXX_COMPILER_ID and when trying to run cmake, get this result:

$ cd luzer
$ git branch -av

@seclorum Hi, thanks for reporting this! I believe the issue will be addressed in #58.
