Over the years packaging of MITK evolved into a completely chaotic spaghetti code that noone is able to really understand anymore. Packaging can take ages and it appears that many things are done multiple times. There also seems to be fundamental issues in understanding the packaging process. Packaging was only patched before releases to get it somehow working but never adapted to newer CMake versions. We also have custom CMake BundleUtilities from Daniel Maleike to speed up packaging but we drift away from the official CMake version of BundleUtilities over time. Over the past years we spend many weeks in trying to understand and fixing our installers. This has to stop and therefore I plan to do a complete rewrite of the packaging after gathering some insights in dummy CMake projects on Windows, Linux, and macOS.
