Error building OSM Renderer: Missing CMakeLists.txt in lunasvg-source/plutovg

[MikaYeghi]

I am following the digital twin tutorial. It says the following: "You first need to build the OSM renderer before proceeding to build CARLA." That is what I do. First, I follow "Part One: Prerequisites" on this page. Second, I clone the CARLA repository and switch to the dev branch without building CARLA (in the link shared above it clearly states that this is a feature of the dev branch only):

(carla-dev) acrl-uiuc@ACRL:~/Mikael/CARLA_latest$ git clone https://github.com/carla-simulator/carla && cd carla && git switch dev
Cloning into 'carla'...

Switched to a new branch 'dev'

Then, I try to build the OSM Renderer before building CARLA, and this is where I encounter a problem:

(carla-dev) acrl-uiuc@ACRL:~/Mikael/CARLA_latest/carla$ make osmrenderer

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at e83e4881a Issue #1045 - Update projection

make: *** [Util/BuildTools/Linux.mk:160: osmrenderer] Error 1

The build does not finish properly because of the error above --- does not contain a CMakeLists.txt file. Has anyone else encountered this error before? How can I fix it?
