VTK 8.1 + Qt 5.7 + CMake

Hi all!

I'm trying to run a Qt application using VTK, but I found this errors:

/opt/Qt5.7.0/5.7/gcc_64/include/QtWidgets/QVTKWidget.h:32: error:
vtkGUISupportQtModule.h: No such file or directory

I've found in stackoverflow/vtkforums that I have to enable the option
VTK_Group_Qt in CMAKE in order to install the QVTKWidget.

When I try cmake with this option, I get:

Make Error at
/usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148
(message):
   Could NOT find Qt4 (missing: QT_WIDGETS_INCLUDE_DIR QT_WIDGETS_LIBRARY)
   (found version "4.8.7")

   CMake/vtkTestingMacros.cmake:357 (vtk_module_test_executable)
   GUISupport/Qt/Testing/Cxx/CMakeLists.txt:44 (vtk_test_cxx_executable)


I don't know what to do now, I have the PATHs on my .bashrc and installed
Qt4 too. Do you know how to fix this problem?

Thank you!
