Alexander,

First, thank you for your reply.  This was exactly the kind of help I
was looking for.

Second, I attempted to follow your instructions.  I am a big proponent
of cmake at work.  I love how simple it is to create a "hello world"
project (particularly when compared to autotools).  However, my head
is spinning with the new jargon needed to properly install a simple
"hello world" package.  Even after reading the docs and wiki I don't
really understand what I am doing, I more or less just tried to copy
it.  Most of the EXPORT and CONFIGURE_PACKAGE docs seem to be geared
toward someone who already knows the "old" way of installing and just
needs a refresher to the new style.  I hope my "hello" project, once
it meets your approval, can be used to assist other new packagers in
the future.

Third, would you please take a look at my updated "hello" project and
the new "hello-client" project?  As you might imagine, hello-client is
an executable that uses the hello library.  I have done something
wrong in hello, hello-client, or both as hello-client fails to
compile.  I suspect that among other mistakes, I should have some
SET_AND_CHECKs in my Config.cmake.in file.  I also suspect that my
hello-client is missing a FIND_PACKAGE reference.
