CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(ImageGridSource) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(ImageGridSource MACOSX_BUNDLE ImageGridSource.cxx) target_link_libraries(ImageGridSource ${VTK_LIBRARIES})
Download and Build ImageGridSource¶
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 Some tarballs may be missing or out-of-date.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 ImageGridSource and its CMakeLists.txt file. Once the tarball ImageGridSource.tar has been downloaded and extracted,
cd ImageGridSource/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:
./ImageGridSource
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.
