If you encounter any issues building a package from this PKGBUILD and/or running the resulting binaries:

DO NOT CONTACT UPSTREAM!!!

This PKGBUILD is not supported nor provided by upstream!

Only leave messages here on the AUR!

Now depends on libpulse and libpipewire-03.so

Package fails to build. I was told by looking-glass maintainers that in-source builds are not supported and that may be a reason.

You are correct. My bad.

@Netboy3; I'm not pulling/building against master submodules or otherwise diverting those definitions to commits not specified by upstream. Each git repo defines the submodule version/commit being used. That means (at the time of writing) for looking-glass it's using cimgui@83f729b (a.k.a. cimgui 1.82), which in turn uses imgui@64aab84 (1.82 + 2 extra). This isn't functioning any differently from the submodules it had already; PureSpice and LGMP.

Thx for adding the new cimgui/imgui dependency. Only thing you should consider is that the devs are currently building against version 1.82 of cimgui/imgui and you are pulling cimgui master which seems to be quite active and might cause LG builds to break or be inconsistent with the way the LG devs use it.
