Subject: [PATCH] vtk: added cross compiling capabilities

vtk can cross compile either with a multi-step compiling scheme using
VTKCompileTools, as reported in
https://cmake.org/cmake/help/book/mastering-cmake/chapter/Cross%20Compiling%20With%20CMake.html#cross-compiling-a-complex-project-vtk,
or with a cross compiling emulator, as shown in
VTK_source_code/CMake/vtkCrossCompiling.cmake, such as qemu.
Given xbps-src capabilities, using qemu is the most convenient option.
