I agree, for the release tarballs, I think it's ok if the asserts are
disabled there. For the Linux distros, I think we should simply leave
the decision to the package maintainer - they should configure the
build in their spec file as desired.

Right. I've enabled the Debug build type now for most of the CI

What's the debugrelease target? I can't find any cmake documentation
about that...? Running "cmake -DCMAKE_BUILD_TYPE:STRING=debugrelease ."
simply seems to compile without any CFLAGS at all, so this build type
does not seem to exist?
