Ubuntu 22.04 cannot find standard libraries

It seems that for Ubuntu 22.04, there is a chance that some of the standard libraries cannot be resolved properly. 
It is due to some issue with clangd. Although the default g++ is looking for g++-11 libraries, clangd looks for the g++-12 libraries.

To resolve, simply run
```bash
sudo apt install g++-12
```
