imgui is purely sourcecode. There are no build artefacts, so no need to create an AUR package.
According to meson docs...
Since 0.49.0 if source_filename or patch_filename is found in the project's subprojects/packagecache directory, it will be used instead of downloading the file, even if --wrap-mode option is set to nodownload. The file's hash will be checked.
So it's likely that anyone who has previously fetched the repo and built into AUR package, has a cached version of the imgui subproject. This will be used regardless of the wrap-mode, so you won't get this error. Pretty sure if you delete your clone and reclone the repo, you'll get this error.

Mangoapp will remain disabled until GLFW version 3.4 arrives which will allow you to choose the backend at runtime. Now stop crying.
