[vtkusers] building and byte swapping

[Dave Semeraro]

Hello,

This has probably been asked before but I could not find an answer by 
searching the archives.
I am building VTK-4.2.1 with CMake 1.6.5 under Linux on an Intel XEON 
system. My question
is, How do you coerce CMake to define CMAKE_WORDS_BIGENDIAN? The reason I want
to do this is so that vtkByteSwap wont. I am writing binary vtk data files 
for input to vtk and if
CMAKE_WORDS_BIGENDIAN is not defined then neither is VTK_WORDS_BIGENDIAN and
so the code in vtkByteSwap swaps the bytes when it reads. The ifdef resides 
in vtkConfigure.h.
I can edit this file by hand and make vtk compile as I wish but that is not 
a very satisfying thing.
I really want to know where I am going wrong. As always, any help would be 
appreciated.

Dave
