Sorry, but the negative impact for other devs and the
whole project are just unbearable.
Stuff got committed meanwhile even so I had to act.
The improvements may be reapplied later when the
negative consequences are under control.
Get rid of global properties and use a target-level properties instead
Limit temporary files by using cmake-generator expressions instead
Avoid function calls at the end configuration, use file(GENERATE) idiom instead
