If you check later for a library (which is probably what you normally
want to do as Drew said) you could also do:

  (eval-when-compile (require 'THELIB))

Then you probably have things in your the library you compile like

(defun my-defun ()
   (require 'THELIB nil t)
   (when (featurep 'THELIB) ...)
