Possibly, I'll look into it - though if possible I'd prefer to replace the use
of `backtrace()` with in-program stack traversal, which would require
`-fno-omit-frame-pointer` (I'm not sure how you'd check that in CMake either)
but would be significantly faster than making the lib call, so if it turns out
to be non-trivial (e.g. if there's some ordering issue in the CMake config)
then it may not be worth it.
