Bug#1013190: openems: Migration from vtk7 to vtk9

[Francois Mazen]

Package: openems
Severity: wishlist
Tags: patch
X-Debbugs-Cc: francois at mzf.fr

Dear Maintainer,

OpenEMS package depends on vtk7 which is quite old and not maintained upstream.

I've succeeded to build OpenEMS with vtk9 by changing Build-Depends from
libvtk7-dev to libvtk9-dev and fixing CMake and build errors.
The patch is attached to this message.

Could you please update to vtk9?

Thanks,

François
