Well, taken from the URL above:

"Go directly to this section for a quick solution."

which links to

http://www.vtk.org/Wiki/CMake_Cross_Compiling#Information_how_to_set_up_various_cross_compiling_toolchains

and there, the third line links to an example that cross-compiles from
Linux to Windows using MinGW.

The trick is writing the toolchain file, which you can get from the
example above and make the necessary changes on the paths to tools, etc.

That was taken care a *long* time ago. Hope it still works.
