macOS C++ CMake project cannot find any C++ header file so clangd fails.

Please describe the problem. For hints on what information is helpful, see: https://clangd.llvm.org/troubleshooting.html

If you can, provide a minimal chunk of code that shows the problem (either inline, or attach it if larger).

C++ file where #Include <memory> or really any standard C++ file is included. None of the includes will resolve.

Logs Please attach the clangd log from the “Output” window if you can. If possible, run with --log=verbose - note that the logs will include the contents of open files! clangd.log

System information Clangd version : 11.0.0 clangd extension version: 0.1.11 Operating system:macOS 10.15

I found add qurey driver help to make it work

  "clangd.arguments": [
+    "--query-driver=/usr/bin/clang++",
  ],

I think this should be the default setting on macos, it was a pain to find this.

Hey, if someone ends on this issue like me I found this snippet from the installation page very useful! It helps generating a compile_commands.json that clangd will use to find your project’s deps 😉

If your project builds with CMake, it can generate this file. You should enable it with:

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1
compile_commands.json will be written to your build directory. If your build directory is $SRC or $SRC/build, clangd will find it. Otherwise, symlink or copy it to $SRC, the root of your source tree.

ln -s ~/myproject-build/compile_commands.json ~/myproject/

• tested on helix editor only but hey, this is the conversation I first got into
