[b8903208]

sorry! i am a new user
i dont't know Cmake how to work?
what is its function?
when i tar Cmake to usr/local in sunOS, then i execute cmake, it show some 
error:(i use vtk4.2)

CMake Error: EnableLanguage was unable to find a CMAKE_MAKE_PROGRAM

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
VTK not found.  Set VTK_DIR to the directory containing VTKConfig.cmake.  
This is either the root of the build tree, or PREFIX/lib/vtk for an 
installation.  
For VTK 4.0, this is the location of UseVTK.cmake.  This is either the root 
of the build tree or PREFIX/include/vtk for an installation.
-- Configuring done

when i execute ccmake, it show:
EXECUTABLE_OUTPUT_PATH          *                                             
LIBRARY_OUTPUT_PATH             *                                             
CMAKE_BACKWARDS_COMPATIBILITY   1.6   

i don't know how to set the EXECUTABLE_OUTPUT_PATH and LIBRARY_OUTPUT_PATH??

and when i gcc some *.cxx examples, it always show not found the *.h 
what i should do??
