QT and external libraries

My project group and I are trying to integrate QT Libraries with the ARIA libraries necessary for operation of an ActivMedia robot.
Initially we modified the qmake.conf file and placed the modified file in the working directory, having added the necessary library flags. Unfortunately, when we run qmake -project, qmake, make the Aria libraries still are not added into the compiler statements.

If anyone could provide help regarding including external libraries, like the ARIA ones, into a QT program, it would be very much appreciated.

If you placed the include (header lib)files in the /usr/bin/qtdir/include
then I found you have to add the following lines in your make file
QTDIR = /usr/bin/qtdir/include
regardless you will have to adjust your make file
if the include files are in a different directory try this
adding a variable pointing to the directory
ARIADIR=/usr/bin/aria (or whatever the path is)
then change the line
INCPATH = .......................
and add
this to it
INCPATH = -I$(ARIADIR)/include or just -I$(ARIADIR) if you included the full path

Hope that helps just a newbie myself so no guarantees.
