Why this specific commit back in May?
For a new recipe, without upstream release, I think starting with just a current commit would be enough.

It's the mavlink version used by the latest mavsdk. The latest mavlink version (which is also included in the recipe) was causing issues, if I remember correctly.

This package is not independent of the options.dialect. Having different dialect means generating different headers, isn't it?

Good point. Thanks! Limited it to just settings.

But pymavlink requires other transitive dependencies that will not be found: https://github.com/ArduPilot/pymavlink/blob/master/requirements.txt, this will most likely fail.

I have tested this and it indeed fails:
CUSTOMBUILD : error : Could not find a version that satisfies the requirement lxml>=3.6.0 (from versions: none) [C:\Users\memsharded\.conan2\p\b\mavli7342ae94e4fe c\b\build\generate_c_headers.vcxproj]
This seems quite a challenge to me.

I replaced the pip install ... && python -m pymavlink.tools.mavgen ... call via CMake with a direct self.run() for a better control over the temporary Python env. A temporary site-packages folder is created in the build folder, and caching is disabled to not pollute ~/.cache/pip.
I have used the same pattern for Python build-time deps in a few other recipes and it has worked without issues, afaik:
Summary
Changes to recipe: mavsdk/2.13.0
Motivation

MAVLink is a very lightweight messaging protocol for communicating with drones (and between onboard drone components).
