Looking. Where can I find the cmake configuration?

Mine (`-DLLVM_ENABLE_ASSERTIONS=On -DLLVM_ENABLE_EXPENSIVE_CHECKS=On`) does not build for other reasons:

  .../llvm/include/llvm/ADT/PointerUnion.h:93:26: error: constexpr variable 'NumLowBitsAvailable' must be initialized by
   a constant expression                                                                                                                                
      static constexpr int NumLowBitsAvailable = lowBitsAvailable<PTs...>();
