[vtkusers] VTK Configuration Errors

[Luca Nicotra]

Ok, now I don't get file-missing errors but still some errors remain. I
already set the CMAKE_BACKWARDS_COMPATIBILITY to 1.4,1.2 and any possible
other version.

This is the complete list of the errors I get:

CMake Error: An attempt was made to access a variable:
CMAKE_WORDS_BIGENDIAN that has not been defined. Some variables
 were always defined by CMake in versions prior to 1.6. To fix this you
might need to set the cache value of
 CMAKE_BACKWARDS_COMPATIBILITY to 1.4 or less. If you are writing a
CMakeList file, (or have already set
 CMAKE_BACKWARDS_COMPATABILITY to 1.4 or less) then you probably need to
include a CMake module to test for the feature
 this variable defines.

What does "you probably need to include a CMake module to test for the
feature this variable defines." means in practice? Include where?
