This switches the default Make build type to `build_type=Release`. This offers: - higher optimization level, including loop vectorization on older GCC - adds NDEBUG define, which disables assertions, which could cause speedups if assertions are in loops etc - no `-g` means smaller install size Downsides are: - worse backtraces (though this does NOT strip symbols) - perf reports may be useless - no function arguments / local variables in debugger (could be of course) - no file path / line numbers in debugger The downsides can be mitigated by overriding to `build_type=RelWithDebInfo` in `packages.yaml`, if needed. The upside is that builds will be MUCH smaller (and faster) with this change. --------- Co-authored-by: Gregory Becker <becker33@llnl.gov>
