I'd like to supply that test, but I'm not certain which way to use for
gathering the linking information.
I only use cmake for my applications, which is of course well supported
by VTK. The tests I saw only use pkg-config, which seems to be the
preferred tool for mingw-cross-env, right?
So I could either try to patch VTK to generate a pkg-config .pc file.
Or I could write a test using a simple CMakeLists.txt file. What do you
prefer?

Although it would be easy for CMake to generate a package-config file, I
did not find a simple solution after a few minutes of googling. I guess
it's some kind of politics not to support this tool.

I think they are related to linking Qt. The Qt installation does not
export a cmake configuration file. I usually use a CMake script based on
https://lists.nongnu.org/archive/html/mingw-cross-env-list/2010-11/msg00069.html
which parses the Qt linking information from the lib/Qt*.prl files.

Based on this script, I just built VTK/Examples/GUI/Qt/SimpleView
without errors.
