THE example on the documentation page can't be compiled

Nobody has claimed this yet.

The documentation page
https://immediate-mode-ui.github.io/Nuklear/
contains ONE prominent example, following directly after the gallery of screenshots.

I could not compile it. There is no command that shows how to compile it, so I reused what I found in the Makefile of the examples folder and adapted it. I just got a lot of error messages.
Starting with one prominent (the one) example on the documentation page and not getting a running example is rather discouraging.

I tried other examples from the examples-folder and had to tweak things there also, to get something that runs and makes sense.

Please fix the one example (or replace it with a working one) and add a line that can be used to compile the code.

Open the prominent example on the Nuklear documentation page and compare it with the compilation commands in the examples folder's Makefile. Verify the example builds and runs, then document a usable compile command on the page; done means a newcomer can compile the featured example without additional tweaks.
