[vtk-developers] compilation and link errors in 3rd part application due to recent changes in VTK

Tue Dec 14 19:12:03 EST 2010

I just merged in a small fix that got things linking again here at
least. Arnaud - if you pull and do a 'cmake .' in the VTK build tree
it will rebuild VTKConfig.cmake, and that should be enough for you to
confirm whether this gets things working again for you too.
