You create an (nameless) function that will set a new `compile-command'.
However, you don't call the function, therefore you don't see any
effect.

If you did
(funcall (lambda () ...
the function would be executed immediately and do what you want.

Certainly you'll want it to execute automatically:
(add-hook 'c-mode-hook (lambda () ...
will automatically call your function when you open a C file.
