Every serious plugin developer probably has to deal with this problem: WordPress is not supporting composer or any dependency management by default. I have written a great plugin which I would like to put into the official repository on WordPress.org.
Problem is: I do not want to write all of those options pages (including network options pages) on my own - this is why I am using the CMB2 library. It is actually a well known framework used by a lot of WordPress developers in order to create options pages: https://github.com/CMB2/CMB2
Most probably it is not a good idea to put the CMB2 library into my Plugin (which would also require constant updates). But what other option do I have? What is a good way to deal with this problem?
