Re API, SVG is an output file format and so is used via obconversion like
smiles, etc.

"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.

Also, I think the functions that caused error are from cairopainter.cpp,
which should be installed in the openbabel library but are missing now. The
already installed libraries are dynamic and I don't know how to manually
add these missing ones. I don't know what was wrong with my openbabel
installation but I just don't seem to be able to get those depict.h related
files and libraries installed.
On another note, I don't mind using SVG. But I can't find the documentation
about its API.
Thanks,
