Tell cmake we need to link Test against vtkHybrid. This is the "catch all" VTK library. If you don't know what to link to, most of the time vtkHybrid will have what you need.
Assign filters. Optional, but useful.

Here is the descriptions for selected lines:

Make cmake to find VTK and Qt4 library and include UseVTK.cmake and UseQt4.cmake, where useful settings are defined. <source lang=cmake> find_package(VTK REQUIRED) include(${VTK_USE_FILE})

find_package(Qt4 REQUIRED) include(${QT_USE_FILE}) </source>

Tell cmake to include additional header directories for out-of-sorce build <source lang=cmake>

  1. support for out-of-source build

INCLUDE_DIRECTORIES(

 ${CMAKE_CURRENT_BINARY_DIR}
 ${CMAKE_CURRENT_SOURCE_DIR}

) </source>

Make cmake to define SRC for all source files, MOC for meta-compiling (class with Q_OBJECT), UI for form files,RCC for resource files.

<source lang=cmake> set(SRC

   optionsDialog.h optionsDialog.cpp
   main.cpp
   mainwindow.h mainwindow.cpp
   application.qrc

)

set(MOC optionsDialog.h mainwindow.h ) set(UI optionsDialog.ui mainwindow.ui) set(RCC application.qrc ) </source>

Setting up for Qt preprocessing : moc.exe, ui.exe, rcc.exe <source lang=cmake> qt4_wrap_cpp(MOC_GENERATED ${MOC}) qt4_wrap_ui(UI_GENERATED ${UI}) qt4_add_resources(RCC_GENERATED ${RCC}) </source>

Assign filters. Optional, but useful. <source lang=cmake> source_group("Form Files" FILES ${UI} ) source_group("Resource Files" FILES ${RCC} ) source_group("Generated Files" FILES ${MOC_GENERATED} ${UI_GENERATED} ${RCC_GENERATED} ) </source>

Tell cmake the project "application"'s source files include all generated files and required libaries.

<source lang=cmake> add_executable(application

   ${SRC}
   ${MOC_GENERATED}   ${UI_GENERATED}  ${RCC_GENERATED} )

target_link_libraries(application ${QT_LIBRARIES} QVTK ) # QVTK is for VTK 5.x. For VTK 6, use ${VTK_LIBRARIES} instead </source>

In MSVC, WIN32 and $(QT_QTMAIN_LIBRARY} are required to remove dummy console window, as follows:

<source lang=cmake> add_executable(application WIN32

   ${SRC}
   ${MOC_GENERATED}   ${UI_GENERATED}  ${RCC_GENERATED} )

target_link_libraries(application ${QT_LIBRARIES} ${QT_QTMAIN_LIBRARY} QVTK ) # QVTK is for VTK 5.x. For VTK 6, use ${VTK_LIBRARIES} instead </source>
