as far as I know there is nothing special about the dual processor, so I 
guess you want to know how to build VTK on Linux in general?

I cut a piece from a Gentoo VTK 5 ebuild, so you get an idea of the 
variables to be set, depending on what you want to use:

         # build list of config variable define's to pass to cmake
         local CMAKE_VARIABLES=""
         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DCMAKE_SKIP_RPATH:BOOL=YES"
#        CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_DIR:PATH=${S}"
         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DCMAKE_INSTALL_PREFIX:PATH=/usr"
         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DBUILD_SHARED_LIBS:BOOL=ON"
         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_SYSTEM_JPEG:BOOL=ON"
         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_SYSTEM_PNG:BOOL=ON"

         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_SYSTEM_ZLIB:BOOL=ON"

                 fi
         fi

                 CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_QVTK:BOOL=ON"

                 # if QT4 is installed, configure for QT4
                 if has_version =x11-libs/qt-4*; then
                         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DDESIRED_QT_VERSION:STRING=4"
                         CMAKE_VARIABLES="${CMAKE_VARIABLES} -DQT_INCLUDE_DIR:PATH=/usr/include/qt4"

                 fi
         fi


         use tcltk && CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_WRAP_TCL:BOOL=ON"
         use threads && CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_PARALLEL:BOOL=ON"
         use patented && CMAKE_VARIABLES="${CMAKE_VARIABLES} -DVTK_USE_PATENTED:BOOL=ON"
         use doc && CMAKE_VARIABLES="${CMAKE_VARIABLES} -DDOCUMENTATION_HTML_HELP:BOOL=ON -DBUILD_DOCUMENTATION:BOOL=ON"


So, construct your own CMAKE_VARIABLES from this source :).

Now run:
         cmake ${CMAKE_VARIABLES} . && cmake ${CMAKE_VARIABLES} .
(twice to prevent errors if you use cmake 2.2.x).


If you have an EM64T, there is a problem with Java (either with Sun or 
Blackdown) so execute this:

sed -e "s/javac/javac -J-Xmx256m/" -i Wrapping/Java/CMakeFiles/VTKBuildAll.dir/build.make

Then execute "make" in order to build VTK.

After make you need to install it onto your system. I'm not really sure 
about this step, but this is the idea:
make DESTDIR=${D} install   (where ${D} is /usr, but I'm not sure).


Then, prior to use VTk set these environmental variables:

         export VTK_DATA_ROOT=/usr/share/vtk/data
         export VTK_DIR=/usr/lib/vtk-5.0
         export CLASSPATH=/usr/share/vtk/lib/vtk.jar"


I hope this gives you a guidance.

Good luck!
