Does it have to be generated? What's the contents of that file after=20
generation and what generates it?

As you discovered, includes are done before targets. You would need seperat=
e=20
invocations of make, to generate the file and get it included.
Maybe this will work, tho I doubt it (I expect the include to screw with th=
e=20
beforedepend target):

beforedepend:
=2Eif !exists(${.CURDIR}/elements.mk)
	${MAKE} ${MAKEFLAGS} -f ${MAKEFILE} genmk
=2Eendif
=2Eif exists(${.CURDIR}/elements.mk)
=2Einclude "${.CURDIR}/elements.mk"
=2Eendif

genmk:
	# do whatever here to generate the mk file

=2D-=20
