[CMake] Find out current CXX_FLAGS at build time?

Thanks. I'm not sure if that's quite what I need, though. These  
variables will expand at cmake configure time. But for IDEs, the  
build style isn't set until build time, so I assume there needs to be  
a separate build-time variable to look at. Maybe I'm interpreting  
things wrong, though.
