[Insight-users] Registration Example Program

[Dill, John]

Hi Luis.

That is the really confusing part.  The files are exactly the same.  Diff
returns no difference.

I tried the HelloWorld copied into a different directory, and it works okay,
although I still have to add those other libraries to the CMakeLists file
for it to link (don't know why).  When I try to link in itkpng instead of
png, itkpng not found, except that it's looking for Insight-1.0.0 when I
only should have Insight-1.2.0.  I think what is happening is that I had
installed an older version of ITK but didn't get it cleaned up so it's using
the wrong version when I'm compiling, and I don't believe I did a gmake
install on the 1.2.0 distribution.  I've got some cleaning to do.

Many thanks,
John
