CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(Cutter) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(Cutter MACOSX_BUNDLE Cutter.cxx ) target_link_libraries(Cutter ${VTK_LIBRARIES})
Download and Build Cutter¶
Click here to download Cutter and its CMakeLists.txt file. Once the tarball Cutter.tar has been downloaded and extracted,
cd Cutter/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:
./Cutter
WINDOWS USERS
Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
