[vtkusers] How to solve this problem when compiling this program about volumerendering?(Albert, Yan)

[YanAlbert]

Hello, everyone.

       I am recently studying volume rendering in VTK, but when compiling a program I met some curious problems, and I have tried to solve it but failed at last. hope someone can tell me how to solve it.

       This is the error when compiling(on Fedora 9).

[albert at localhost Cxxbin]$ make
Linking CXX executable VolumeExample
CMakeFiles/VolumeExample.dir/VolumeExample.cxx.o: In function `main':
VolumeExample.cxx:(.text+0x309): undefined reference to `vtkVolumeRayCastCompositeFunction::New()'

And here is the related code!!
