Include statements causing trouble

As you know that the files from the include directory can be included without specifying relative or full path, eg : file at path : llvm/include/llvm/Transforms/Utils/pass.h can be included as #include llvm/Transforms/Utils/pass.h . This creates problems while writing code because VScode can’t locate the file and lot of features such as ‘code completion’ and ‘Go to Definition’ etc cant be used. Is there a way to fix this issue?

Thanks in anticipation
