Download and Build BorderWidgetQt¶

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

cd BorderWidgetQt/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:

./BorderWidgetQt

WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
