In the latest release CCT's SAGA C++ implementation doesn't require a set SAGA_LOCATION environment variable anymore (at least as long as the installation has not been moved from the --prefix directory it was configured and built with). If no $SAGA_LOCATION is set it internally defaults to the directory used during ./configure --prefix=... This doesn't free you from the need to properly set your LD_LIBRARY_PATH, but that's another issue, I guess.
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.
That is easy to solve: just set SAGA_LOCATION at the top of your Makefile, and not in the environment. Make does not care where the value comes from - but it needs _some_ means to find the make includes... hope that helps, Andre.
