While m4sugar is from GNU Autoconf (which is GPLv3), it's properly listed as a dependency and ISC is GPL-compatible, so there's no licensing issue that I know of. The code explicitly seems to avoid GNU m4-specific features for BSD compatibility, and it goes well beyond header-only testing. While shell scripting is a valid approach, m4conf provides structured macros for maintainable configuration and advanced features like runtime CPU capability detection. As far as I can tell, the code is well-documented and organized, though you raise fair points about the tradeoffs between shell and m4 approaches, but as others have mentioned it (and seen in example m4 file), it is extremely simple to use and works with third-party libraries as well. |

You mean build-time (with m4conf, that is).
