### CMakeLists.txt

    cmake_minimum_required(VERSION 2.8)

    PROJECT(Bottle)

    find_package(VTK REQUIRED)
    include(${VTK_USE_FILE})

    add_executable(Bottle MACOSX_BUNDLE Bottle.cxx )

    target_link_libraries(Bottle ${VTK_LIBRARIES})

### Download and Build Bottle

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

    cd Bottle/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:

    ./Bottle

WINDOWS USERS

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