[vtkusers] ow to build standalone VTK IO

[Albert Akhriev]

Hi All,

I need vtkIO compiled on remote machine where I run a solver and save 
the results into a file using vtkIO.
The problem is that I do not have root privilege, so compilation of the 
full VTK package is problematic
because there is no OpenGL on remote machine (even Mesa).
In fact, I do not need graphics in there, rather vtkIO solely.
Please, let me know how can I modify makefiles to build vtkIO only and 
skip all other stuff?
Thank you in advance.

Albert
