How is this a “CMake” compile error? Since CMake is not a C compiler, I don’t understand how using CMake causes this to be a compile error when it’s not an error without CMake. Is CMake passing different options to clang?

Also, I suggest using auto instead of what we did here.

Yes, CMake is currently passing different compile flags, and I'm not sure why this doesn't compile, but with typeof(updateBlock) as the variable type it has unrecognized identifier syntax errors.

Good idea!
