libxfcegui4.h is not found when building libxfprint module in xfprint.
Created attachment 586 Patch to include libxfce4gui header path in libxfprint Patch for Makefile.am and Makefile.in to add @LIBXFCEGUI4_CFLAGS@ to libxfprint_la_CFLAGS
fixed with revision 21942 FYI: you only need to change @LIBXFCE4UTIL_CFLAGS@ into @LIBXFCEGUI4_CFLAGS@ because the second depends on the first one.
