The makefiles in LSU's SAGA C++ implementation (e.g.
$SAGA_LOCATION/share/saga/make/saga.application.mk) still need either
SAGA_ROOT or SAGA_LOCATION to be set. A user that writes a SAGA app
using an existing SAGA C++ installation therefore still needs to set
SAGA_LOCATION, otherwise he cannot include saga.application.mk in the
makefile of his own application. It's not clear to me whether that's a
bug or not, but it seems to conflict with the quoted statement.
