Why can't clang find the file ?

Clearly, compile_commands.json is in build, also my configuation as below

    "clangd": {
      "command": "clangd",
      "rootPatterns": [
        "compile_flags.txt",
        "compile_commands.json"
      ]

But When I add #include "buffer/lru.h"，It reminds [clang pp_file_not_found] [E] 'buffer/lru.h' file not found

Make a soft link for compile_commands.json to project root.
