I think it won't work this way. Because in this case swig can only make a binding cxx file, i.e. I'm not using SWIG_LINK_LIBRARIES. Further steps will be made via npm/node-gyp. That's why I get:

CMake Error: CMake can not determine linker language for target: jsonrisc
CMake Error: Cannot determine link language for target "jsonrisc".

I'll stick for custom command for now.

Thanks.
