Hi Chris!

Thanks for the review.

I tried, but:
1. breeze is a different package from the ones in the repo (url is
https://github.com/Alexhuszagh/BreezeStyleSheets).  It does not seems to
be compiled, I can try to package it.
2. there are files in lib/cmark that are not present in the cmark
distribution (thei are .h files generated by their .h.in), so I cannot
extract our cmark source directly
   - I tried keeping those files, but build fails [[failed-build]].  Not sure if it's
   a patched version or if it's an older one.  But I can investigate
   probably
3. Should I do the same for fonts file? It depends on Noto (that we have
in the store) and on OpenMoji (I can package it)

Just for reference, I attached the current WIP package definition
([[current-package-definition]] which is getting complex.  Is there a
better way to achieve the "delete a folder, but keep some file"?)


Thanks!
Nicolò
