[SAGA-RG] usage of SAGA_LOCATION

In my case, I don't have root access to my machine and can only access my 
home-dir. So installing in /usr/local/ is not really an option, and I need 
the $SAGA_LOCATION set.

If I could install it in /usr/local/ and also have the java implementation 
installed, I still have to set $SAGA_LOCATION to the java implementation. 
Does this effect the C++ implementation since $SAGA_LOCATION is set, and it 
overrides internal C++ default?
