Describe the Issue

I have had this issue for a few weeks now, I cannot update from the Arch Aur.

I have since tried to manually build the source with the same results. The files that are requested in the cmakefile.txt are indeed in the repo but I do not have the relevant skills to debug any more than I have.

Two things you can check here, as it seems the ImGui submodule isn't properly checked out:

1. Run git submodule init && git submodule update in the main project dir, this should properly initialize submodules. Without init, update doesn't have anything to work on as it only updates initialized submodules.
2. If the submodule is checked out and the issue persists, try switching to the v1.90.2 tag in vendor/imgui manually.

I should probably update the build instructions to use the separate for commands.

[b14ckw1d0w]

Thank you for the reply. I can now build the project and have notified the Aur maintainer of the change required.

Good to hear! I've also updated the build instructions accordingly, closing the issue then.
