I have started using autotools for the C++ applications I create (very much as an amateur). I typically use assert statements during development, and would disable these by using -DNDEBUG when the release version is built. How should I configure things so that when a user installs from the tarball they compile by default with the -DNDEBUG option?
Do you actually see a performance difference from adding -DNDEBUG? In GraphicsMagick (which uses many assertions) I did not see a tangible performance difference so I did not worry about it.
The Autoconf default is already to compile with debug enabled so it seems that leaving assertions enabled by default is also a reasonable default.
