orionp and I were discussing on irc today, the idea to add
-DCMAKE_BUILD_TYPE=ReleaseWithDebInfo
to %cmake by default in /etc/rpm/macros.cmake , while making it easy to
set/override manually, similar to how %_cmake_lib_suffix64 is currently
handled.
the idea being that many cmake projects default to Release (or not,
sometimes goofy things like Debug)
The idea being that many projects default to CMAKE_BUILD_TYPE=Release and
end up pulling in -O3 (and -DNDEBUG).
There's 2 issues we'd like some wider input. What disadvantages or side-
effects are there to:
1. setting a default CMAKE_BUILD_TYPE?
2. building with -DNDEBUG by default?
I own several packages that use cmake and I've taken to setting the release type to RelWithDebugInfo like you suggest. One question I've had but never gotten around to asking is: Regardless of whether you use Release or RelWithDebugInfo, should we be building with -O3? It seems odd that the rpm macro defaults to doing something that is explicitly against the packaging guidelines.
Thanks,
Richard
