I'm looking for "what am I doing wrong" help. "cmake build" is failing, and I don't know where to start.

Log:

keybounceMBP:obs-studio michael$ git status

  It fails with the following output:

Just as a quick example question: How do I "clean" and have cmake regenerate everything from scratch? What stuff in "build" is input to cmake, and what stuff in there is output from cmake?
