Returning to build environment can fail with: remove before copying

[omus]

I was using the wizard when I ran into this:

...
			# Step 4: Select build products

ERROR: The build has produced no binary artifacts.
       This is generally because an error occurred during the build
       or because you forgot to `make install` or equivalent.

How would you like to proceed? (CTRL-C to exit)
 > Return to build environment
   Retry with a clean build environment
   Edit the script
