This behavior makes includes in modules shipped with CMake still look
in the module directories defined by the project.  The change does not
effect building IceT on its own.  (At least, there are currently no
modules included that are also included with CMake.)  However, this is
currently necessary to prevent warnings in ParaView.

Support latest means of loading packages.  Add check for version.
Export targets correctly.

This was emperically shown to be a better value than 2048 (at least
on Intrepid).

Does not do anything yet.

All the IceT libraries contain some special instructions for the
builds (such as install targets).  Encapsulate these in a single
macro.

The motivation for this change was to move the compiler warning
flags specifically to the files compiled in IceT libraries (or,
more to the point, outside of the test files).  I don't feel the
test scaffolding needs the same strickness as the libraries.
Also, I need to set an environment variable in one of the tests,
and there is no means of doing that when maintaining ansi
compatibility.

The magic k is set at configure time with a CMake variable.  This
value can be overridden at run time with an environment variable.

Apparently this flag is not ubiquitous amongst gcc compilers.

Many parts of the code allowed implicit conversion from a 64 bit value
to a 32 bit value.  A lot of this was using IceTSizeType as a 32 bit
integer.  Using the compiler warnings, remove the conversions or make
them explicit.

Also converted the CompressionSize test to no longer depend on OpenGL.

This catches arithmetic with void * pointer, which is not supported by
MSVC.

The copyright on all source now has the current preferred legalize.  All
source now also states that the license is New BSD.

The install target was installing several files that should not
have been installed including one that no longer exists.

Changed the build system to include all of the strategies into the
IceTCore library.  The separation was mostly a coding convienience
on the library side.  It was rather silly for the user perspective
as you always used both libraries.  Also, this was becoming less
convienient as the core library really relies on things in the
stratgies library and you have to carefully pass pointers and
structures around.

This change is driven by some errors I am encountering that might
be caused by using uninitialized strategy objects.  My next step is
to just identify stratgies by enumerations.  This will get rid of
any such problems.

FindIceT.cmake did not really do anything that CMake does automatically
with configure files.  To ge the automatic CMake stuff to work, I
renamed ICETConfig.cmake to IceTConfig.cmake.

All UseICET.cmake really did was add the include directories and link
libraries for everybody.  Since you really should be using
target_link_libraries anyway, this only left the include directories.
It's just as easy to add the include directories as it is to include
the use file.

Also changed icet to IceTCore.

I while ago we started using IceT for the acronym that is the name
of this software.  It is about time we changed all the references
in the code.

I turned on a bunch of compiler warnings for gnu in my default
build.  This fixes these issues.

Previously, the OpenGL and MPI libraries were linked to everything
with a general LINK_LIBRARIES CMake command.  Now, only use
TARGET_LINK_LIBRARIES to bind libraries to a specific target.  Not
only is this cleaner, but it also helps verify that libraries that
should not depend on these libraries don't.

Adding a formal interface to image objects.  The interface
functions are defined and implemented, but the rest of
the image.c code is a mess.  The old stuff still needs to be
deleted and the rest of the methods need to convert to the
new methods.

Was previously calling FIND_PACKAGE(Glut), which was working
on Mac because it has a case insensitive file system.  But
when I moved to Linux, which has a case sensitive file system,
it failed to find the FindGLUT.cmake package file.

As a first step to removing dependence on OpenGL of the core IceT,
remove all the GL* types (i.e. GLint, GLboolean, GLfloat, etc.).
This removes most of the dependence on OpenGL right there.  (There
are only a limited amount of OpenGL function calls left.

As part of this process I have also moved the basic header files out
of the include/GL directory and into the base include directory.
I also changed the names from ice-t to IceT to better conform to the
current name convention.

Previously the tests used some hack-ish code for creating windows
on X and Win32.  Unfortunately, this meant that I could not run
the tests on Mac, where I now do most of my development.  Rather
that make my own knock off again, I am using a well-established
portable library.

COMP: Disable tests on mac because they cannot open an OpenGL window.  To enable the tests, we would either need to make a new version of glwin that supports mac or to switch all the tests over to use glut (or something equivalent).  I'm too lazy to do either right now.
