[vtkusers] linux configure/compilation problem with CMake load shared object.

[Dongbai Guo]

I am using Fedora and VTK4.2 and the latest CMake.

The configuration is as following:
 BUILD_EXAMPLES                   
OFF                                         
 BUILD_SHARED_LIBS                
OFF                                         
 CMAKE_BACKWARDS_COMPATIBILITY    
2.0                                         
 CMAKE_BUILD_TYPE                                                              

 CMAKE_INSTALL_PREFIX             
/data/dev/public/vtk/linux_install-4.2      
 VTK_DATA_ROOT

 VTK_USE_HYBRID                   
OFF                                         
 VTK_USE_PARALLEL                 
OFF                                         
 VTK_USE_PATENTED                 
ON                                          
 VTK_USE_RENDERING

 VTK_WRAP_TCL                     
OFF                                         



Got error when running configuration:
