My 50 cents about the inclusion of C/C++ libraries in Hugo is that can only happen if
- This is a functionality that Hugo really, really needs, and
- It’s not available as a native Go library and it it’s not likely to happen in the near future.
- It is available from a trusted source with a license that’s compatible with Apache 2.
E.g. LibSASS back in the days, or the Webp encoder from Google.
Govips does not fall into that category, I think.
