I would suggest to move examples to examples-src or to src/examples.

At the very least - if renaming is not an option - I would suggest to note within the Readme.md that this folder consists of sources and not running examples.

I would have expected that a root folder that is called examples would provide running examples, instead of sources that were not built; while the ones that are fully working are residing in the build folder. The fact, that those example sources are partially working was very confusing to me

This took me at least 2 hours. I was able to resolve it thanks to a forum reply. In retrospection I could have found the reason for the non-working examples if I were to open index.html or started browsing the build folder, but that was not an intuitive approach for me.
