I would suggest it's the VS Code Extension regime somehow being incompatible with entirely valid 'CMakeLists.txt' files.Most probably the old CMakeLists.txt is not compatible with the new system, and it makes the mess you see.
There is no reason why a './build' directory needs to contain anything to successfully build a project from the command line or from within VS Code. That it's wanting to find something specific in './build' to undertake a build is down to the VS Code Extension.
The accepted wisdom has been, that if builds aren't working when expected to, delete the './build' directory and start again. That has worked in the past, had for the OP, still works for me with my VS Code builds, but seemingly not with the new VS Code Extension regime.
