I recently switched to Ubuntu 12.4 (64bit) and I am trying to compile

From what I understand this is due to a ld patch:
https://fedoraproject.org/wiki/UnderstandingDSOLinkChange
yes, sounds like we are not linking against all vtk libs we need.
I am not very experienced with cmake.. what I id:
mkdir build
cd build
cmake ..
make && make install
(in a script with sudo)
How would it be possible to add that linker flag -lvtkIO ?
I think the attached patch should fix it. Can you give it a try, since
it's difficult for me to reproduce the problem? Thank you!
Cheers,
Carsten
