I'm inclined to agree, but you don't have a build system and that is
precisely why you need to handle this here. If cups-pdf was using a
Makefile, autotools or cmake, then dh_auto_* would just work (in most
cases). But since you are invoking the compiler from debian/rules
directly that's the place to set up CC.

Guillem Jover has a draft[1] for a file /usr/share/dpkg/buildtools.mk or
similar that would set up variables such as CC. Thus when that
materializes, you can replace my patch with including such a makefile.
