(In reply to Ralf Habacker from comment #1) > This could also be set centrally via the project configuration. It was planned to use 'Substitute:' in the project configuration. However, this option does not distinguish between build and runtime dependencies, so that an adjustment of only the build dependency is not possible. After accepting https://build.opensuse.org/request/show/1074827 and https://build.opensuse.org/request/show/1074822 it is therefore necessary to manually adjust all 146 packages in question, which is done in a mass change.
