It is the output of free command:

              total        used        free      shared  buff/cache   available
Mem:         766868       39820      583444       10004      143604      668164

Where did you get the sources? Because the build instructions reported  in the qt3d README seem outdated.
I simply cloned the sources from git://code.qt.io/qt/qt3d.git  and the made qmake & make. 
Maybe I didn't get the last commits or something like that. ..
