if that means kdebindings from KDE 4.5, it should work.  (At least in
the sense that it is also the version Debian ships, which mostly works
for others.)

I can't make sense of that.  Either way, ldd would indicate whether the
linker could find the smoke libraries or not.

Did compilation actually work?

Are there any compilation warnings if you run:
cd commonqt && make clean && qmake && make

Lacking other options, I'd personally try to uninstall the
system-provided smoke and compile it manually, just to see whether it
makes a difference:

1. git clone git://anongit.kde.org/smokegen
   cd smokegen
   cmake CMakeLists.txt -DCMAKE_INSTALL_PREFIX=/opt/smoke
   make install
   cd ..

2. export LD_LIBRARY_PATH=/opt/smoke/lib:$LD_LIBRARY_PATH

3. git clone git://anongit.kde.org/smokeqt
   cd smokeqt
   cmake CMakeLists.txt -DCMAKE_INSTALL_PREFIX=/opt/smoke
   make install

4. cd /path/to/commonqt
   make clean
   qmake LIBS=-L/opt/smoke/lib/ INCLUDEPATH=/opt/smoke/include/
   make

Keep in mind that LD_LIBRARY_PATH still needs to be set when invoking
the Lisp later.

ldd output for me is then:

------------------------------------------------------------------------
$ ldd libcommonqt.so | grep smoke
        libsmokeqtcore.so.3 => /opt/smoke/lib/libsmokeqtcore.so.3 (0x00007f7e8d1d9000)
        libsmokebase.so.3 => /opt/smoke/lib/libsmokebase.so.3 (0x00007f7e8b123000)
------------------------------------------------------------------------
