Editor features like "Go to Definition" will not be able to find the source file for functions from a library that is being linked in. Current behavior appears to only look at source files added/linked to a project. A workaround is to add/link the files/folders of the source to the project but this is not ideal. And ideal situation would be to allow the user to simply specify additional directories to CCS for clangd to parse. Maybe then the IDE can add it to the generated compile_commands.json.
