Yep, others are now experiencing the exact same thing. Everything compiles 
except phonon.

These are generated by some macros in qglobal.h. They are included in every 
smoke library. I'm not sure yet why it doesn't work. Fact is that smokegen 
doesn't pick up any phonon header, only the qglobal.h header file. g++ on the 
other hand doesn't seem to find *anything*, not even qglobal.h (or rather, the 
preprocessor is doing some weird stuff. It doesn't seem to include any header, 
except smoke.h and phonon_includes.h, without any contents). At least that's 
what I gathered from looking at the output of g++ -E.

For the moment, you can disable the phonon bindings by passing
-DDISABLE_Phonon=TRUE
to cmake. Everything else should compile fine.
