SUMMARY

On MacOS big sur

STEPS TO REPRODUCE
1. use clazy to compile a sample c++ file has code that should trigger checks
2. 
3. 

OBSERVED RESULT
no diagnostic

EXPECTED RESULT
should print diagnostic

SOFTWARE/OS VERSIONS
macOS: big sur 11.5.2

https://invent.kde.org/sdk/clazy/-/blob/master/src/Clazy.cpp#L180 this returns nullptr on MacOS Big Sur 11.5.2
So the checks are not run. I believe it has something to do with Apple Clang. A example clang plugin build with llvm source works as expected (but not with Apple clang).

I tried another example clang plugin with clazy's cmake file, getTranslationUnitDecl also returns nullptr.

The llvm used in linking is llvm12 from brew, clazy wraps itself around Apple clang. However manually load ClazyPlugin with llvm12's clang from brew works as expected.
