build failure: fatal error: SQLHeavy.h: no such file or directory

I can seem to get feedler build. Specifically, I've hit a roadblock with a fatal error concerning SQLHeavy. I've checked, and as far as I can see, I've installed all of the requisite dependencies and *-dev packages. The output from CMake and make are as follows:

ch2lah@SBCS627LHLT:~/.branches/feedler/build$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr

Any assistance would be greatly appreciated, if it does turn out to my error and/or something at my end (I'm running an up to date version of Ubuntu 12.10).
