Can someone tell me the magic CMake changes that I need to make so that the C++ compiler will display warnings and terminate? I broke the build yesterday because I had not seen a warning that then showed up in the build. I have these two options set in CMakeCache.txt: //Enable compiler warnings. LLVM_ENABLE_WARNINGS:BOOL=ON //Fail and stop if a warning is triggered. LLVM_ENABLE_WERROR:BOOL=ON

That seems to work (see below). $ cd
