Your link order is still wrong.  The linker is trying to resolve symbols for libvtkRendering.a, but can't resolve it for any libraries that follow libvtkRendering.a.  vtkTransform is defined in libvtkCommon.a.
So to satisfy the above, you have to specify -lvtkRendering *before* -lvtkCommon.  That's normal linking behavior for pretty much any platform but Windows.

Do this instead

LIBS            += -L/usr/local/lib/vtk \
                -lQVTK \
                -lvtkHybrid \
                -lvtkVolumeRendering \
                -lvtkIO \
                -lvtkRendering \
                -lvtkGenericFiltering \
                -lvtkGraphics \
                -lvtkImaging \
                -lvtkFiltering \
                -lvtkCommon \
                -lvtkftgl \
                -lvtkfreetype \
                -lvtkDICOMParser \
                -lvtkexpat \
                -lvtksys \
                -lvtktiff \
                -lvtkjpeg \
                -lvtkpng \
                -lvtkzlib
