As you can see, this is a Subsurface class issue, not related to Qt.
are you compilling from qmake, from cmake?

1 - make sure you are in the latest master
2 - do a grep -rIs SybsyrfaceSysInfo and check that those functions do
exist in the source code ( hint, they do. )
3 - try to fix qmake if necessary

if all that fails, you also have a script that should download everything
and compile it correctly in the scripts folder.
