Generate the C++ dependencies at configure-time
We use the -MG preprocessor option to the compiler to ask it to check
all #includes and tell us what's missing. Then our own rules will
generate the moc and uic files that the .cpp #include.
Unfortunately, our rules make uic generate output in qt-ui/ for
qt-ui/*.ui, while the compiler generates rules for no directory. We
need to fake it by forcing the generation.
