http://www.emacswiki.org/cgi-bin/wiki.pl/DirVarsPackage

With the dirvars.el package you create a file called .emacs-dirvars in
the root directory containing

    compile-command: "cd ~/dev/foo; ant"

Then this setting is automatically used by the root directory and all
subdirectories.


I use the following to store the current compile-command in a
.emacs-dirvars file.

    (defun vjo-create-dirvars-file (cmd)
      (interactive)
      (if (file-exists-p ".emacs-dirvars")
          (progn
          (find-file ".emacs-dirvars")
          (goto-char (point-max)))
        ;; else
        (progn
          (find-file ".emacs-dirvars")
          (insert ";; -*- emacs-lisp -*- \n")
          (insert ";; VJ\n")
          (insert (concat "compile-command: <QUOTE>" cmd "<QUOTE>\n"))
          (replace-string "\"" "\\\"" nil (previous-line 1) (point))
          (replace-string "<QUOTE>" "\"" nil (previous-line 1) (point))
          (save-buffer))))
