Bug#979306: QVTKOpenGLWidget.h: No such file or directory

[Drew Parsons]

Package: libvtk9-qt-dev
Version: 9.0.1+dfsg1-6
Severity: normal

This is another report from trying to build avogadrolibs against VTK9
(Build-Depends: libvtk9-qt-dev), following on from Bug#979073
(thanks for configuring RenderingContextOpenGL2).

avogadrolibs is now emitting this build error:

We can ignore the vtkActor.h error for the purposes of this bug report.
vtkActor.h is provided by libvtk9-dev, I'll chase it up separately and
work out why avogadrolibs didn't find it. Perhaps libvtk9-dev needs
some fix somewhere like
/usr/lib/x86_64-linux-gnu/cmake/vtk-9.0/VTK-targets.cmake in order to
provide the include directory, or perhaps (and more likely)
avogadrolibs is not even asking cmake to find VTK the right way.

What I'm filing this bug for is the error on QVTKOpenGLWidget.h .
It is not provided by libvtk9-qt-dev.  The strange thing
though, is that it is referenced in the VTK9 build log:
  Generating code for file GUISupport/Qt/QVTKOpenGLWidget.h...
It is included in the docs. vtk9-doc provides
/usr/share/doc/vtk9/html/QVTKOpenGLWidget_8h.html

So there seems to be an inconsistency between libvtk9-qt-dev and
vtk9-doc.  Should libvtk9-qt-dev be providing QVTKOpenGLWidget.h ?
Does debian/libvtk9-qt-dev.install (if not libvtk9-qt.install) need to
be updated after adding RenderingContextOpenGL2?
