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.

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

find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})

Tell cmake to include additional header directories for out-of-sorce build

# support for out-of-source build
INCLUDE_DIRECTORIES(
  ${CMAKE_CURRENT_BINARY_DIR}
  ${CMAKE_CURRENT_SOURCE_DIR}
)

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.

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 )

setup for Qt preprocessing : moc.exe, ui.exe, rcc.exe

qt4_wrap_cpp(MOC_GENERATED ${MOC})
qt4_wrap_ui(UI_GENERATED ${UI})
qt4_add_resources(RCC_GENERATED ${RCC})

Tell cmake we want to compile Test.cpp into a binary called Test.

ADD_EXECUTABLE(Test Test.cpp)

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.

TARGET_LINK_LIBRARIES(Test vtkHybrid)
