[vtkusers] Error generating vtkGLSLShaderLibrary.h with vtk-5.3.x after upgrading to CMake-2.6.2

[Elvis Dowson]

Hi,
        I did an update of the VTK sources from the cvs repository and  
re-ran the whole build process and it's working fine now. Wonder what  
happened because of the CMake-2.6.2 upgrade ?  :-)

Best regards,
