<pre>
    I get this error on Windows with both version 15.0.0 and 17.0.3, but "--sysroot" options is worked on Mac with version 15.0.0……
```
clangd.exe: Unknown command line argument '--sysroot=E:/mcu/GNU_Arm_Toolchain/arm-none-eabi'.  Try: 'E:\mcu\LLVM\bin\clangd.exe --help'
clangd.exe: Did you mean '--sync=E:/mcu/GNU_Arm_Toolchain/arm-none-eabi'?
```
I haven't try this command option on Mac with Ver 17.0.3.
