I am getting this error, which seems to originate in openroad: runs/user_proj_example/logs/placement/basic_mp.log:[ERROR] Cannot find any macros in this design. (The full log is available here: https://pdk.libresilicon.com/caravel-build.html)

First thing is the

Makefile

needs

bash

it doesn' work well under

sh

Yes, I couldn't figure out where this error comes from
