I didn't go with `export()` because it solves only half the problem. The exported targets are only valid for the build tree. The equivalent for the install tree would be `install(EXPORT)` together with the appropriate per-target install options. I don't think the second path is feasible for Polly, because it requires invasive changes to LLVM's cmake setup. Thus, I'd have to manually export the targets for the install tree anyways. I still could've used `export()` for the build tree, but I prefer the symmetry of my solution.

Updates wrt. to the inline comments coming soon.
