Tweaking the build to turn on various debug options in GCC and enable -Wall -Werror on only our executable configs because turning them on globally causes most of the dependencies to fail. One thing to note is if you try to move the -D_GLIBCXX options from the project() to the executable() then you get segfaults inside the libc++ and other places. This is because the ABI changes when you enable these options, so you have to recompile _all_ dependencies with these options.
