I would recommend using environment variables to override the default
installed directories.  To run you program from build directory can then
use a wrapper script that sets those environment variables appropriately
and call your progam this script can be used for running tests too.  As
an example you can see the 'pre-inst-env' script of Automake [1] which
is generated at configure time.
