[vtkusers] vtk Ruby CMake error

[Chase Yarbrough]

Hello,

I am trying to build VTK with ruby wrappings.  I downloaded the source 
tarball from http://www.gfd-dennou.org/arch/ruby/products/ruby-vtk/, 
untarred it and tried to CMake it with wrap_ruby and 
build_with_shared_libs ON, but get the following CMake error:

Error in CMake code at
C:/vtk ruby/VTK/wrapping/Tcl/vtkDetermineTkResources.cmake:4:
Unknown CMake command "VTK_GET_TCL_TK_VERSON"

Note that I have wrap_tcl set to OFF.  Any ideas what is going on?

Also, I'm not sure exactly what I should be setting RUBY_INCLUDE_PATH 
and RUBY_LIBRARY to.

Thanks,
Chase Yarbrough
