[CMake] HOW DO I: Build VTK with CMake/ExternalProject_add against Qt with Cocoa on OS X?

[Dave Partyka]

I am "pretty sure" carbon/cocoa are switched on/off by whatever QT tells VTK
to use: (VTK/CMakeLists:306)  If this logic is not working correctly please
let me know.

IF(VTK_USE_QT)
# Now require Qt 4.5.0 or later
  SET(QT_MIN_VERSION "4.5.0")
  SET(QT_OFFICIAL_VERSION "4.5")
  SET(QT_REQUIRED TRUE)
  SET(QT_USE_QTSQL 1)
  FIND_PACKAGE(Qt4)
  IF(NOT QT4_FOUND)
    MESSAGE(SEND_ERROR "Qt ${QT_MIN_VERSION} or greater not found.  Please
check the QT_QMAKE_EXECUTABLE variable.")
  ELSE(NOT QT4 FOUND)
    # enforce Carbon or Cocoa in VTK for Qt/Mac
    IF(Q_WS_MAC)
      IF(QT_MAC_USE_COCOA)
        SET(VTK_USE_CARBON OFF CACHE BOOL "Build VTK with Carbon" FORCE)
        SET(VTK_USE_COCOA ON CACHE BOOL "Build VTK with Cocoa" FORCE)
      ELSE(QT_MAC_USE_COCOA)
        SET(VTK_USE_CARBON ON CACHE BOOL "Build VTK with Carbon" FORCE)
        SET(VTK_USE_COCOA OFF CACHE BOOL "Build VTK with Cocoa" FORCE)
      ENDIF(QT_MAC_USE_COCOA)
    ENDIF(Q_WS_MAC)
  ENDIF(NOT QT4_FOUND)
ENDIF(VTK_USE_QT)
