CMake has support for packages, so that once something like VTK or ITK is
installed, a single command will pull in the correct settings.  So you first
need to call FIND_PACKAGE() which sets up the build variables for includes
and libraries.  The CMake guide has more info on this:

This is just because the include path is not set; using FIND_PACKAGE() will
fix this by setting include and lib paths.

Here is a working example from a simple appliation of mine:



PROJECT(vgf)

# Required libraries

FIND_PACKAGE(ITK)
IF(ITK_FOUND)
   INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
   MESSAGE(FATAL_ERROR "Cannot build without ITK.  Please set ITK_DIR.")
ENDIF(ITK_FOUND)

FIND_PACKAGE(VTK)
IF (VTK_FOUND)
   INCLUDE(${VTK_USE_FILE})
ELSE(VTK_FOUND)
   MESSAGE(FATAL_ERROR "Cannot build without ITK.  Please set VTK_DIR.")
ENDIF(VTK_FOUND)

# The application

ADD_EXECUTABLE(vgf vgf.cxx)

TARGET_LINK_LIBRARIES(vgf popt ITKCommon ITKIO ITKBasicFilters vtkCommon vtkImaging vtkGraphics vtkIO vtkFiltering vtkHybrid vtkRendering)



The libraries are specified individually so as not to include every one, but
you could use ${VTK_LIBRARIES} if you wish.

Hope this helps...
