Getting the Config files right so that they are relocatable, which is especially 
important under Windows, is not trivial.
Look e.g. here, this also does something I don't fully understand, it uses a 
cmake variable coming from somewhere else:

It may work, but I don't know. It looks strange at least.

So, CMake 2.8.8 comes with the module CMakePackageConfigHelpers.cmake, which 
makes this much simpler:

This is IMO a big point for requiring 2.8.8.
I want to be able to point people to use this stuff so they end up with working 
Config-files which also are maintainable.

This will make my life easier and result in better working Config files for
