I build clang from source with gcc-6.3, using CMake and ninja. I need to 
make sure a particular gcc command line compiler option is added as part 
of the build that is generated by CMake. How do I do that with the 
latest clang source ? Previously the CMake gui program listed a 
particular CMake field for changing the command line option, but I 
forget what the name of that CMake field was. It is no longer showing in 
the CMake gui program with the latest llvm/clang source.
