How can I import the library into an existing Xcode project

[JSmithOner]

I'm pretty new to the whole c++ ecosystem.
I've cloned the repo
installed cmake
builded the xcode project

I usually code using js with the usual node.js structure and now I'm facing an issue.

I would like to use the libdatachannel inside an existing XCode project that has been automatically created with its dependencies linked to it.

So my question is how can I link libdatachannel to my existing project an use it?

Should I compile to lib file with headers, should I import the builded libdatachannel xcode project inside the existing one? should I use native git project.

Thanks in advance
