clangd to teach emacs c++

clangd

Install clangd to have IDE support in emacs:
https://clangd.llvm.org/

Add following snippet to ~/.emacs:
(require 'eglot)                                                                                                                                                                                                                                                                     
(add-to-list 'eglot-server-programs '((c++-mode c-mode) "clangd"))                                                                                                                                                                                                                   
(add-hook 'c-mode-hook 'eglot-ensure)                                                                                                                                                                                                                                                
(add-hook 'c++-mode-hook 'eglot-ensure)

Create file ~/.clangd with:
CompileFlags:
    Add:
    [
        '--cuda-gpu-arch=sm_80',
        '--cuda-path=/usr/local/cuda',
        '--include-dir=/usr/local/cuda/include',
        '-std=c++17'
    ]
