Ugh, apparently I'm out of the loop here. While looking at the mkspecs, I
noticed the (to me) new *_RELEASE_WITH_DEBUGINFO qmake variables. That lead me
in turn to try out the (still mac-only) -debug-and-release once more which
prints the somewhat cryptic message that its not required anymore thanks to
separate debug information. Reading the output of configure -help then finally
gave me -force-debug-info, so I'm now trying this out.
./configure ... -release -force-debug-info
Is that the recommended way to get this done?
Thanks, sorry for the noise (probably)
