[opensuse-factory] How to tell Thumbleweed from Leap in the spec file?

It seems Leap lacks a lot of libraries that Factory/Thumbleweed has. Many packages fail to beild because of this, because they have in in Build Requires. The situation is not going to change in future versions. Is there a way to make a check if the distro is leap or Thumbleweed in the spec file? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
