Just to make it clear: I think this is the wrong approach.

Just to avoid creating a tier0 KF5 entity, we create a script which does, when 
executed, what this KF5 entity naturaly would be.


Or, maybe we should discuss another question first: what makes a library a KDE 
frameworks library ? What properties do KDE frameworks libraries have ?


Can KDE frameworks libraries of different versions be mixed together ?
E.g. can I build a tier2 library against different versions of tier1 
libraries, or does this in general only work if they have the same version ? 
If so, they wouldn't necessarily share the same KDE frameworks version 
number...

Can I install different libraries from the KDE frameworks set of libraries to 
different locations and use them together ?

If the answer to these questions is yes, then KDE frameworks is really just a 
set of loosely coupled libraries, which of course can have different versions.

If the answer is no, i.e. if these libraries should still be seen as one 
coherent package, then there should be a package they all depend on, the KF5 
package, as small as it may be. A library containing only a function which 
returns the version, or something like this.
Depending on this small (header only ?) library would be the burden necessary 
to get the stamp "you are a KDE framework library".
