Is it possible to compile LibCarla client without installing Unreal Engine?

[poyrazogluyigit]

I plan to use CARLA's C++ API in a container. Going through the setup scripts, it's apparent at a glance that the script itself relies on the existence of $UE4_ROOT. I have no idea about the dependencies of libcarla-client, so here is my question: Is there a certain workaround (for instance, pointing to independent C/C++ compilers in the setup file) that is known not to break libcarla-client?
