CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(RandomGraphSource) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(RandomGraphSource MACOSX_BUNDLE RandomGraphSource.cxx) target_link_libraries(RandomGraphSource ${VTK_LIBRARIES})
Download and Build RandomGraphSource¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download RandomGraphSource and its CMakeLists.txt file. Once the tarball RandomGraphSource.tar has been downloaded and extracted,
cd RandomGraphSource/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:
./RandomGraphSource
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.
