[vtkusers] CMake Book and Beta

[Ken Martin]

Hello Folk,

Two quick announcements; There is now a CMake User's/Developer's Guide that
you can purchase at http://www.kitware.com/products/cmakebook.html and the
beta version for CMake 1.8 is available for download from
http://www.cmake.org. 

Changes from CMake version 1.6.7 to 1.8 include:

The custom commands have been rearchitected to use a more understandable
signature. The old signature should still work. ctest has been enhanced and
can produce testing dashboards compatible with Dart in many cases. A new
FILE command has been added that supports reading, writing, and globbing of
files. A new help target is created for all Makefiles so you can do nmake
help (or make help) Command line options (-D) for cmake no longer require
the type of the argument. The on-line help for cmake has been significantly
improved. Run cmake --help for more information. Support for windows paths
and filenames that include &. Support for files with multiple "." in them
for nmake. More Modules report results to CMakeOutput.log and
CMakeError.log. The performance of dependency tracing and analysis in CMake
has been significantly improved. Both ccmake and CMakeSetup have some minor
GUI improvements. And of course a number of minor bug fixes and
enhancements.

Thanks
Ken
