./CarlaSetup.sh: line 130: cmake: command not found

I'm trying to build Carla (ue5-dev) from source in a Docker container, but it fails. The build ends with the following messages:

+ echo 'Installed CMake 3.28.3.'
Installed CMake 3.28.3.
Found CARLA content.
Found CARLA Unreal Engine at /home/carla/CarlaUE5/UnrealEngine5_carla. Assuming already built...
Configuring the CARLA CMake project...
./CarlaSetup.sh: line 130: cmake: command not found

I'm following the build instructions on https://carla-ue5.readthedocs.io/en/latest/build_linux_ue5/

A minimal Dockerfile is attached. (remove .txt)
build_carla.sh.txt

Not pretty but it works for me: I have cmake installed and in my PATH, however when echoing the PATH from within CarlaSetup.sh the cmake path is not included... so I added
export PATH=$PATH:/opt/cmake-<yourversion>/bin
in CarlaSetup.sh and Util/SetupUtils/InstallPrerequisites.sh infront of the first cmake call :)

If you found a nicer fix please let me know :)

I found a "better" solution, which is to add it to the path when calling the setup script.

sudo -E env "PATH=/opt/cmake-3.28.3-linux-x86_64/bin:$PATH" GIT_LOCAL_CREDENTIALS=github_username@github_token ./CarlaSetup.sh

This way you don't need to edit the .sh scripts.

While this worked, I then had a lot of issues with directory permissions due to the fact the directories were created by root and therefore root is the owner of those directories. I had to sudo chown -R $USER:$USER ~/CarlaUE5/ and a number of other directories to be able to launch UE5.
Therefore I think it's actually best to build using the interactive mode of the script without sudo, instead of unattended mode.
