Debian Sid has evince >= 3.0. This is going to require some massaging 
because the pkg-config file is named evince-view-3.0.pc. your version 
would be called evince-view-2.3.pc. We use to do something similar to 
this with portaudio versions. Theses lines would needed to be added for 
2.3.

PKG_CHECK_MODULES(EVINCE, evince-view-2.3 >= 2.3)
CFLAGS="$CFLAGS $EVINCE_CFLAGS"
LIBS="$LIBS $EVINCE_LIBS"


PKG_CHECK_MODULES(EVINCE, evince-view-3.0 >= 3.0)
CFLAGS="$CFLAGS $EVINCE_CFLAGS"
LIBS="$LIBS $EVINCE_LIBS"

Perhaps I need to create a couple booleans to set the results of the 
pkg_check. Something like VERSION2 VERSION3.
sudo code:

if (VERSION2 || VERSION3)
  CFLAGS="$CFLAGS $EVINCE_CFLAGS"
  LIBS="$LIBS $EVINCE_LIBS"
else
  stop ./configure with error message
