wayland-protocols need to be a makeopt, or the make process not include wayland support,which is bad for a clean chroot build

I'm unable to use this at all in wayland. If I manually build the package from the github, I don't have this issue.

Fails to link at runtime with the newest version of ffmpeg:

Maybe a dumb question, but can this be written to link against /usr/lib/libavcodec.so directly so new updates to ffmpeg don't require an update of linux-wallpaperengine? Unless I'm misinterpreting this error message.

@Almamu After adding permissions it works. I see that the third line of PKGBUILD defines _pkgname but the whole script doesn't use it.

@wustdsh to me seems to work after the install command, but I've added the permissions for it nonetheless (will take some minutes for the change to hit AUR). If that fixes it for you I'll do some cleanup and use some variables where It should instead of hardcoding names.

chmod +x ${pkgdir}/opt/${_pkgname}/linux-wallpaperengine is also needed

Should add: install -d -m755 "${pkgdir}/usr/bin" before line 38 of PKGBUILD. Otherwise it will report an error：No such file or directory.

Installed using paru, but it won't run with: linux-wallpaperengine: error while loading shared libraries: libcef.so: cannot open shared object file: No such file or directory The problem seems to be in package().

Where do I put the assets folder?
