Interesting, thank you for pointing that out.
I just tried something inspired by that (looking at
https://github.com/ROCm/ROCm-Device-Libs/blob/amd-stg-open/cmake/OCL.cmake#L129)
but when I deleted the configured `.rsp` file it wouldn't know how to rebuild
it. It did reconfigure and rebuild when I deleted the `.rsp.in` file. It might
be I've done something wrong, but though I like your suggestion I might stick
with this one as I've verified it can handle being deleted.
