NixOS C++ Dev Template

Having issues getting clangd to detect std header files despite clang++ and g++ having no issues. So this template/workaround solves this.

I assume this is due to some wrapper script nonsense.

As a workaround I use bear to generate the necessary paths/arguments to get clangd to pick these up.

bear -- clang++ main.cpp

In the generated compile_commands.json. There is a command for generating the main project but also a temporary object file.

I assume this is more weird wrapper stuff (Bear does not support nixos clang wrappers)

You need to move the cxx_isystem related flags as these are where the c++ stdlibs are kept. Also just rename them to isystem otherwise they dont work for whatever reason.
