The doubling is coming from the fact that you're using both
--libdir=$(ROOTLIB)
at configure time and
DESTDIR=$(ROOT)
at install time. You want to drop the former use of $(ROOT) and simply do
--libdir=/usr/lib
The LDFLAGS=-L$(ROOTLIB) and CPPFLAGS=-I$(ROOTINCLUDE) should be enough to
get the compilation and linking steps to use the files in your proto area.
