Build error after running switch_ms-van3t-CARLA.sh

[jakir-ansari]

After installing CARLA, OpenCDA and then running the switch_ms-van3t-CARLA.sh script, I am getting the following error upon executing "./ns3 build":

ninja: build stopped: subcommand failed.
Finished executing the following commands:
cd build; cmake --build . -j 7 ; cd ..

I am thinking that it may be due to a bug in the adapt_files.py script but I'm not sure.

Note: I installed CARLA 0.9.12 externally and OpenCDA externally as well through conda. I am running on Ubuntu 20.04.
