Append sources out of current working directory at the bottom of compile_commands.json
Append sources out of current working directory at the bottom of compile_commands.json

libTooling-based tools search for compile_commands.json from the first source path, and cascade lookup parent folders until find it. Pushing sources out of current working directory at the very end of compile_commands.json can guarantee the first source in this file is inside the current working folder or its children folders, which secures OCLint finding the proper compile_commands.json.
