Hi,

I ran make -j build_franka=1 and encoutered errors. Here is an excerpt:

Any idea what is causing the issue? Thank you!

[zhbihao]

I resolved the issue. For anyone with the same problem, change the PROTO_LIB protobuf in CMakeLists.txt to PROTO_LIB protobuf::libprotobuf and see if it works!

This worked for me too! thanks @zhbihao

@zhuyifengzju @ut-rpl-robots could this be fixed on main? It's a bit frustrating that the installation scripts don't work! Thanks.

[zhuyifengzju]

Feel free to submit PR for review or create a fork. I've graduated and no longer have access to franka panda robots to verify the correctness of the scripts.
