I updated to 3.20 today and during the initial setup, I noticed that libexecinfo-dev was not available. Turns out it's a glibc thing; whilst Alpine uses musl.

I verified, via ccmake, that EXECINFO is indeed not found (as expected) but HAVE_EXECINFO_H seems to be set, because it is included.

Any ideas how I can work around that?

Kind regards!
