An alternative, that seems to be cross platform, is to populate
variables when emacs start. This is what I do here:

#+begin_src emacs-lisp
;; **** fetch env variables from zshrc
(let ((vars (split-string-and-unquote (shell-command-to-string ". ~/.zshrc; export") "\n")))
  (mapcar (lambda (X) (let ((var_val (split-string-and-unquote X "=")))
                        (setenv (car var_val) (cadr var_val)))) vars)
  (setq exec-path 
        (append
         (split-string-and-unquote (getenv "PATH") ":")
         exec-path)))
#+end_src
