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>

setup 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>

Tell cmake we want to compile Test.cpp into a binary called Test. <source lang=cmake> ADD_EXECUTABLE(Test Test.cpp) </source>

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. <source lang=cmake> TARGET_LINK_LIBRARIES(Test vtkHybrid) </source>
