Ah, you didn't mention that the src/lib and include directories had
their own subdirectory structure, so I assumed otherwise.

(add-hook 'find-file-hooks
          (lambda ()
            (let ((alternate-file
                   (replace-regexp-in-string "/include/"
                                             "/src/lib/"
                                             buffer-file-name
                                             t ; fixedcase
                                             t))) ; literal
              (when (and (not (equal buffer-file-name alternate-file))
                         (file-exists-p alternate-file))
                (find-alternate-file alternate-file)))))
