Desktop (please complete the following information):

• OS: [e.g. Windows] Ubuntu
• Version [e.g. 10] 22.04

Additional context

We doesn't support LLVM 14. At least LLVM 15 is needed

OK I will add version check in cmake

There is another issue reporting compile error with LLVM 17 #152. It would be better if we can document the needed LLVM version(s).
