Alternatively, each package could request some version of ECM and this version 
would be downloaded individually (e.g. by KDECMakeSettings.cmake) for each 
package, and would not be installed at all (or via a switch use the system 
provided one), but would be only available in the buildtree.
This would have the downside that when chosing the download-option, when 
building all KF5 libs each of them might download their own copy of ECM.
