Download and Build MutableGraphHelper

Click here to download MutableGraphHelper and its CMakeLists.txt file. Once the tarball MutableGraphHelper.tar has been downloaded and extracted,

cd MutableGraphHelper/build 

If VTK is installed:

cmake ..

If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

make

and run it:

./MutableGraphHelper
