[CMake] Small, complete CPack example?

[Chris Wolf]

I'm looking all over for an end-to-end basic example of using CPack
to create a package with a single shared library target.  It can
even be with the TGZ generator.

I already checked these pages:

http://www.cmake.org/cmake/help/cpack-2-8-docs.html#see:FrequentlyAskedQuestions
http://www.itk.org/Wiki/CMake:CPackConfiguration
http://www.cmake.org/pipermail/cmake/2008-September/024003.html

...and nothing helps.  My CMake file just has a single shared 
library target and when I run "make package", the built 
library gets copied to the destination directory,
however the *.tgz file is empty but the generated
"install_manifest.txt" does have the path of the library in
the destination directory.  The generated shell archive
is also empty, so is the generated *.pkg and *.dmg.


The question is, how to make the build artifacts go into
the package?  A basic (even very basic) example would be
helpful.

Thanks,

Chris Wolf
