You may have libcairo installed. The question is whether it was found when you
compiled Open Babel or not.
"Manually" adding files isn't going to work - either libcairo was found when
you ran "cmake" or not.
You can check with "ccmake ." and look for the CAIRO bits.
I'm not sure what you mean by "API" for SVG. Open Babel will output an SVG.
There's no API.
