[Insight-developers] CMake variable name inconsistencies

[Williams, Norman K]

I noticed some CMake variables in the ITK build system that have
inconsistent naming. I don't know exactly what the best solution to this
will be but I think we need to get things consistent before people get
accustomed to them:

ITKV3_COMPATIBILITY -- this is a top level option, and it ends up in what
the CMake-GUI calls 'Ungrouped Entries' -- it should be named
ITK_V3_COMPATIBILITY, in which case it would be grouped with the other ITK
variables

But there is also Module_ITKV3Compatibility -- which is off by default,
but is interlocked with ITKV3_COMPATIBILITY.  If you turn on
Module_ITKV3Compatibility, it's a config error unless ITKV3_COMPATIBILITY
is also turned on. Shouldn't the Module_ option turn on
ITKV3_Compatibility?

It's a little weird if you actually look closely with cmake-gui at the ITK
variable complement. There are Module_<module name> variables that are
default off, like Module_ITKV3Compatibility. But if you enable them and
re-run Configure, they disappear!
