You need to run generate.py first. It needs a better error message to inform the user.

Can this be automated as part of running cmake?

It could be. https://cmake.org/cmake/help/latest/command/execute_process.html But it will make the configure time longer.

That seems ok. Better to keep the build process as simple as possible.
