David, something is wrong with this on my system (OSX 10.6 with gcc, cmake 2.8.1, vtk 5.6). I am compiling a simple example from the wiki (*), however, it seems that the variable ${VTK_LIBRARIES} is empty (kits, however, are ok). This is my configuration:

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

PROJECT(PP)

FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})

MESSAGE("VTK:              ${VTK_FOUND}")
MESSAGE("VTK_INCLUDE_DIRS: ${VTK_INCLUDE_DIRS}")
MESSAGE("VTK_LIBRARY_DIRS: ${VTK_LIBRARY_DIRS}")
MESSAGE("VTK_KITS:         ${VTK_KITS}")
MESSAGE("VTK_DIR:          ${VTK_DIR}")
MESSAGE("VTK_LIBRARIES:    ${VTK_LIBRARIES}")

ADD_EXECUTABLE(PP a.cpp)

IF(VTK_FOUND)
  TARGET_LINK_LIBRARIES(PP ${VTK_LIBRARIES})
  MESSAGE("==> WITH LIBS")
ELSE()
  TARGET_LINK_LIBRARIES(PP vtkHybrid)
  MESSAGE("==> *NO* LIBS")
ENDIF()


As you can see, the variable isn't filled with any item:

Am I missing something?

By the way, why isn't cmake warning about checking for vtk? It finds it, but no output like "Check for working VTK" is flushed to the console.

Thanks!
