Comment:
I can build libcyaml manually fine but xbps-src can't find "cyaml/cyaml.h":
```
src/mem.h:15:10: fatal error: cyaml/cyaml.h: No such file or directory
   15 | #include "cyaml/cyaml.h"
      |          ^~~~~~~~~~~~~~~
compilation terminated.

`srcpkgs/libcyaml-devel` symlinked to `srcpkgs/libcyaml`.
Maybe someone with more packaging experience can see the issue?
