I've just verified that, and you are right :)

device.cc is not in the .vcproj / .vcxproj files, while say matrix.cc is 

malkia ~/p/cairomm $ git grep matrix.cc

malkia ~/p/cairomm $ git grep device.cc
cairomm/filelist.am:  device.cc \

I'm not sure how the .vcproj / .vcxproj are generated, or maybe they are 
maintained manually, but it looks like this file needs to be added there.

It seems that the projects for building cairomm missed that source file, as the linker error seems like it is missing a C++ symbol, not a C symbol (as in Cairo)-so do a search for it and add it into the "cairomm" project.
