@adamm: could you have a look at the spec file for this request? Especially at two things where I'm not sure whether I did it right:

• The conditional BuildRequires for gcc10 for Leap 15.6. This is necessary because some constructs are needed which are not supported by standard gcc-7. Is this the right way to do this?

• And I had to add a set of %dir lines to the %files section because my local builds else complained about a directory not owned by any package. I don't know why this was not the case before, especially as I do not need this on some of my private builds. See e.g. https://build.opensuse.org/package/show/home:letsfindaway:experimental/OpenBoard which builds nicely without that.
