Error while build LibCarla Client

[awiswasi]

Hey guys,
I have built my CARLA 0.9.14 from source with Unreal Engine 4.26, and I am using it with ROS bridge.
I wanted to create a bounding box UI to detect other cars in the ego vehicle's front view the same way done in /opt/carla/PythonAPI/examples/client_bounding_boxes.py. From my understanding, I would need LibCarla's Client API in order to compile and build my program (I am using CMake).

When I tried to make LibCarla in my /opt/carla/ directory, I got this error:

BuildLibCarla.sh: Building LibCarla "Server.Release" configuration.
ninja: no work to do.
[0/1] Install the project...
-- Install configuration: "Server"
BuildLibCarla.sh: Success!
BuildLibCarla.sh: Building LibCarla "Client.Release" configuration.

I also tried building LibCarla with CMake using the CMakeLists.txt provided in /opt/carla/LibCarla/cmake/, and I got the same error for -DCMAKE_BUILD_TYPE=Client.
Does anyone know how to fix this, or another way to use LibCarla with CMake?
Thanks!

Hello,
I am facing same issue due to the params.obb doesnt exist in the Recast lib,
any news please ?

Go to the carla root, delete build folder and do a make PythonAPI that should fix it if you have proper dependencies
