As far as VTK is concerned, *building* the example *is* a test. If it
has tests, running them too would be great as well. Basically, the
command for the test should be:

    ctest --build-and-test <source> <build> -- \
    "-DCMAKE_BUILD_TYPE=${CMAKE_BUILD_TYPE}" \
    --test-command "${CMAKE_CTEST_COMMAND}"
