In the past, there have been only a few modules that needed /bigobj,
and they're all in unittests IIRC.  If you are running into other
modules that now need it, an upstream patch that sets /bigobj for
just those modules would be very welcome.  Search the CMakeLists.txt
files for /bigobj to find examples of how to do this.
