It was previously possible to add a compiler option to the build of llvm/clang using CMake. Yet when I tried the cmake-gui program against the latest llvm/clang updates the cmake setting to add compiler optons when building llvm/clang was no longer there. How do I do this with the latest version of llvm/clang ?
Can you be more specific as to what you are trying to do, and what it actually does? An example would be great!

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.

I see that this is a change to the CMake gui problem, not a change to clang. The CMake gui program no longer lists common CMake variables. The one I needed was CMAKE_CXX_FLAGS. I had to manually add it.
When configuring I use:
-DCMAKE_CXX_FLAGS:STRING=<my-custom-flags>
for instance:
-DCMAKE_CXX_FLAGS:STRING=-DENABLE_MY_EXPERIMENTAL_CHANGES
This works fine for '-D' etc., but I haven't tried it for other options.
