Fedora 27 VTK 7.1.1 with Qt 5 - qt

Question

I have an application that uses VTK and Qt 5. While running this I get following backtrace

It looks like there is some mismatch between QT 4 and 5 causing error in library initialization. So I checked the lddtree output

It shows the Qt4 dependencies along with Qt5 dependencies. Then I checked the Qt dependencies of libvtkGUISupportQt.so. That shows it depends on Qt4 only.
$ ldd /usr/lib64/vtk/libvtkGUISupportQt.so.1 | grep -i qt

In vtk mailing list They say setting the variable VTK_QT_VERSION to "5" should work. But I doubt because the libvtkGUISupportQt.so depends on Qt4 as compiled. However I set that variable in my CMakeLists.txt. And as expected it didn't work.
set(VTK_QT_VERSION "5" CACHE STRING "Expected Qt version")
mark_as_advanced(VTK_QT_VERSION)
FIND_PACKAGE(VTK 7.0 REQUIRED COMPONENTS vtkGUISupportQt vtkIOImport)
message(STATUS ${VTK_MODULES_DIR})
INCLUDE(${VTK_USE_FILE})
# Find the QtWidgets library
FIND_PACKAGE(Qt5 COMPONENTS Core Widgets Svg Charts REQUIRED)
So now what is the solution ? I once heard VTK 7 links to Qt5. So was that wrong ? However in my Mac it worked fine even before 3 months. Now my Mac uses Vtk 8 with Qt5 (default). May be it was Vtk 7 with Qt5 few months back. I don't know because I have done some updates very recently.
I prefer installing with dnf So that I can easily ship. Both Vtk and Qt are installed with dnf (in Fedora) and brew (in Mac) But If I now compile and install Vtk8 from source would that conflict ?
Another tricky solution could be bypass QVTKWidget and create a QWidget that does the same job as QVTKWidget. If that is easy. I don't know how feasible that is.

While building Vtk with Qt5 there may be issues with other dependencies (I don't know, may be with python 3). But so far libvtkGUISupportQt can be compiled with Qt5. So I think there can be both libvtkGUISupportQt4 and libvtkGUISupportQt5 packaged in the binary distribution. The first one can be used for the dependent packages that have not been worked on yet.
