It actually is, so I'm good there ;-)

And I've fixed that, so now it actually packages the correct files.

But, next question ;-)

Now that I am using a relative (to CMAKE_INSTALL_PREFIX) installation 
scheme, I'd also like to have my TGZ/TZ/ZIP package to work that way. 
But the files in the .tgz have names starting with my application name 
(package name) and then the default install path:

$ tar ztvf cgreen-1.0.0-beta3.tar.gz
-rwxr-xr-x Thomas/None   91772 2012-11-25 21:13 
cgreen-1.0.0-beta3/usr/local/bin/cgreen-runner.exe
-rwxr-xr-x Thomas/None  187260 2012-11-25 21:13 
cgreen-1.0.0-beta3/usr/local/bin/cygcgreen-1.dll
-rw-r--r-- Thomas/None    4552 2012-10-02 16:52 
cgreen-1.0.0-beta3/usr/local/include/cgreen/assertions.h
-rw-r--r-- Thomas/None     659 2012-08-31 00:00 
cgreen-1.0.0-beta3/usr/local/include/cgreen/breadcrumb.h
-rw-r--r-- Thomas/None     463 2012-08-15 19:20 
cgreen-1.0.0-beta3/usr/local/include/cgreen/cdash_reporter.h

So I'd like to lose the "cgreen-1.0.0-beta3/usr/local/" bit. I've hunted 
and experimented with CPACK_INSTALL_PREFIX, 
CPACK_PACKAGE_INSTALL_DIRECTORY, CPACK_PACKAGING_INSTALL_PREFIX, etc. 
etc. most of which are very poorly documented. I even found 
CPACK_TOPLEVEL_TAG which from the docs ("Directory for the installed 
files") looked like it could have something to do with this.

Any assistance would be greatly appreciated!
