Ok building in a clean chroot worked, I will figure out why it failed on my main system later.

It seems that way currently. I could successfully build a package on three different systems. Dirty and clean builds alike.
And the output of pkg-conf is how it should be. The lib is available.
But I am currently at a loss what is happening. Especially if you can build other (AUR) packages? That link to wlroots? What happens if you try to build cage? Did you customize makepkg.conf? Maybe you could try to build the source directly? It would at least tell us if it generally doesn't work or something on the way happens. Another method would be to look into building in a clean chroot. The arch wiki has a section on that

Yeah, just cloning the pkgbuild and doing makepkg -si results in the same error. the output of pkg-config --libs wlroots-0.18 is -lwlroots-0.18. I assume something is wrong on my end?

pkg-config --libs wlroots-0.18 executes successfully?
And just for completeness: Could you please try to build the package with just makepkg?

How do you try to build the package, Max_UA9000?
And what is the output of pacman -Qi wlroots?

Hello, I cannot compile on a fully up to date system, Run-time dependency wlroots-0.18 found: NO (tried pkgconfig and cmake) I have wlroots installed.

Any particular reason why there should be a variant without xwayland, enihcam?

can we have a labwc version without xwayland compiled in? please.

okay so apparently it's a wlr-randr's job

wlr-randr --output eDP-1 --scale 1.5
