But I meet the following error while running the above command by `M-:
(info "(auctex)Adding Support for Macros") RET`:

user-error: Info file ‘auctex’ does not exist; consider installing it


I install auctex with straight by the following configuration:

```emacs-lisp
(use-package auctex
  :straight (:type git :host nil :repo
"https://git.savannah.gnu.org/git/auctex.git";
           :pre-build (
                               ("./autogen.sh")
                               ("./configure" "--without-texmf-dir"
"--with-lispdir=.")
                               ("make")
                               ;;or
                   ;;(shell-command "./autogen.sh && ./configure

                   )
