I’m sure I’m missing something as I work through the initial steps but the files (specifcially the CMakeList.txt) contained in the Step 2 download don’t seem to be migrated from Step 1. They’re essentially blank.

Do I need to recreate the file in Step 2 by copying the requisite lines before getting to the new TODOs? I can’t copy the Step 1 file since that would overwrite the new TODO notes. This is not addressed in the tutorial text.

Just as bad, the CMakeList.txt file in the MathFunctions sub-folder is, at the start of the tutorial, identical to the one in the project root directory. No help is provide to clarify to a beginner what the contents of this “sub” CMakeList.txt should be. Does it need repeats of cmake\_minimum\_require() and project() commands?

It’s got to be me because no one else has complained, so what am I not understanding?
