- Drop vtk-Rinterface-uintptr_t.patch as the related plugin has
been retired.
- Drop vtk-compat_gl: Building against OpenGL1 has now been
deprecated with version 8.1.0, and the examples don't build
against it already; so, drop all specfile and related
modifications catering to OpenGL1 bindings.
- Update to version 8.1.0:
* Full release notes at https://blog.kitware.com/vtk-8-1-0/.
- Turn OFF building against system libharu, since libharu
upstream seems dead, while vtk's included libharu has new
features essential for building vtk 8.1. Drop BuildRequires on
libharu.
- Does not build against java 10, so ensure at most java 9 is
used by using appropriate versioning for java-devel
BuildRequires.
- Drop cmake options no longer used for build.
- Drop VERBOSE=1 for make: it makes the compilation too verbose
making brp checks for code warnings too slow to execute; this
reduces build time by nearly half.
- Enforce Qt4 for openSUSE <= 1320 explicitly because Qt5 is now
the default option.
