Summary:                    Generators create empty archives using component
groups
Description: 
Packaging of component groups seems to be completely broken in CMake 2.8.3:
generated packages are empty.

The problem seems to be that CPack installs all files in a single file system
tree, regardless of what component they belong to, but then expects to package
them from per-component trees.

Steps to Reproduce: 
1. Download attached file, "source.tar.gz"
2. tar -xzvf source.tar.gz
3. mkdir build ; cd build; cmake ..
4. make package

Afterwards, running "find _CPack_Packages/" will produce something like the
following:

_CPack_Packages/
_CPack_Packages//Darwin
_CPack_Packages//Darwin/TGZ
_CPack_Packages//Darwin/TGZ/SomeToolkit
_CPack_Packages//Darwin/TGZ/SomeToolkit/documentation
_CPack_Packages//Darwin/TGZ/SomeToolkit/documentation/usr
_CPack_Packages//Darwin/TGZ/SomeToolkit/documentation/usr/local
_CPack_Packages//Darwin/TGZ/SomeToolkit/headers
_CPack_Packages//Darwin/TGZ/SomeToolkit/headers/usr
_CPack_Packages//Darwin/TGZ/SomeToolkit/headers/usr/local
_CPack_Packages//Darwin/TGZ/SomeToolkit/libraries
_CPack_Packages//Darwin/TGZ/SomeToolkit/libraries/usr
_CPack_Packages//Darwin/TGZ/SomeToolkit/libraries/usr/local
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local/doc
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local/doc/SOMEFILE
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local/include
_CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local/include/header.h
_CPack_Packages//Darwin/TGZ/SomeToolkit-development.tar.gz
_CPack_Packages//Darwin/TGZ/SomeToolkit-runtime.tar.gz

Clearly, the two package files are both installed below

 _CPack_Packages//Darwin/TGZ/SomeToolkit/usr/local/

but the package archives are created from

  _CPack_Packages//Darwin/TGZ/SomeToolkit/documentation
  _CPack_Packages//Darwin/TGZ/SomeToolkit/headers
  _CPack_Packages//Darwin/TGZ/SomeToolkit/libraries

which are empty.


Additional Information: 
I have observed essentially the same behaviour using PackageMaker generator on
Mac and ZIP on Windows.
