Note that you can customize compilation-finish-functions to do all sorts
of things; you can e.g. send a desktop notification:

#+begin_src elisp
(defun my/compilation-notify (buffer results)
  (require 'notifications)
  (notifications-notify :title (buffer-name buffer) :body results :timeout 0))

(add-to-list 'compilation-finish-functions 'my/compilation-notify)
#+end_src

':timeout 0' should ensure that the notification popup remains until you
dimiss it manually.

Writing a function that adds « "Compilation Finished" and red, and
flashing, etc. » to the mode-line is left as an exercise to the reader
:)
