Just linking to it would be easier.  However, the file markdownrenderer
requires access to implementation details of the struct cmark_node
(it includes the file node.h, which is not installed by cmark, and fails
with: ../src/renderers/markdownrenderer.cpp:83:23: error: invalid use of incomplete type ‘const cmark_node {aka const struct cmark_node}’)

I replaced references such as `node.as.heading.level` to
`cmark_node_get_heading_level(node)` and so on.  I could compile it (by
also adding -I/gnu/store and -lcmark to the build process), and markdown
seems to be working (tested here
gemini://tilde.team/~supernova/blog/this-is-a-test-of-using-markdown.md).

I'm going to send a patch to the author, linking to this mail exchange.

I'll let you know.
