Version troubles when linking with VTK and OpenCV

I'm trying to build a computer vision project which uses cmake, and requires OpenCV 3, which in turn seems to need VTK. I have OpenCV 3.0.0 and vtk already installed. Everything compiles fine. When it links, I get:

[ 77%] Linking CXX executable /home/darenw/SW/src/introlab-find-object-6dc66d5/bin/find_object
/usr/bin/ld: warning: libvtkFiltersTexture-6.1.so.1, needed by /usr/local/lib/libopencv_viz.so.3.0.0, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libvtkIOExport-6.1.so.1, needed by /usr/local/lib/libopencv_viz.so.3.0.0, not found (try using -rpath or -rpath-link)
...a zillion more lines like these...

/usr/local/lib/libopencv_viz.so.3.0.0: undefined reference to `typeinfo for vtkWriter'
/usr/local/lib/libopencv_viz.so.3.0.0: undefined reference to `vtkPolyData::SetStrips(vtkCellArray*)'
/usr/local/lib/libopencv_viz.so.3.0.0: undefined reference to `vtkInteractorStyle::EndTimer()'
...another zillion lines like these...

So, cmake thinks libvtkFiltersTexture-6.1.so.1 and siblings are missing? Let's have a look at what libraries are available...

=> ls /usr/lib/libvtkFiltersTexture*
/usr/lib/libvtkFiltersTextureJava.so         /usr/lib/libvtkFiltersTexture.so.1
/usr/lib/libvtkFiltersTexturePython27D.so    /usr/lib/libvtkFiltersTextureTCL.so
/usr/lib/libvtkFiltersTexturePython27D.so.1  /usr/lib/libvtkFiltersTextureTCL.so.1
/usr/lib/libvtkFiltersTexture.so

=> ls /usr/local/lib/libvtkFiltersTexture*
ls: cannot access /usr/local/lib/libvtkFiltersTexture*: No such file or directory

Cmake is looking for libvtkFiltersTexture-6.1.so.1 but I have only libvtkFiltersTexture.so.1 According to pacman I have
pacman -Qs vtk
local/vtk 6.3.0-5
A software system for 3D computer graphics, image processing, and visualization

What do I need to do to get this computer vision project to link? I suspect something isn't right with the cmake files for this project.

@darenw, are you using these packages from the AUR or the main repositories? I am asking because you have opened this thread under the AUR Issues forum.

opencv is from AUR. Aha, I just checked... I have a libopencv*3.1.0 files (and symlinks for 3.1) in /usr/lib, and libopencv*3.0.0 files (and symlinks to 3.0)in /usr/local/lib. Maybe that is troublesome? VTK is /usr/lib only, installed by pacman. I did a major system upgrade less than a month ago.
