I was able to reproduce it with that, but I also tried this:

 add_custom_target(${PROJECT_NAME}-c2
   COMMAND C:/Qt/5.6/msvc2015/bin/qmllint.exe ${CMAKE_CURRENT_SOURCE_DIR}/test.qml
   )

The output does not appear in this case either.  No execute_process
is involved, and qmllint is invoked directly by msbuild.  This has
something to do with qmllint changing output behavior when it is
executed inside a VS IDE (MSBuild) build.
