Why do two build steps (6 and 7) have to be done to satisfy the file depends after the touch? I must be doing something wrong with the file depends above, but I cannot see what it is.
Actually, this bad behaviour was due to a long-standing (at least from 2.8.0) bug in CMake -E touch which truncates the time to the nearest second for the file it creates rather than using an accurate time. So the time stamp was being truncated to a time that was less than the file creation date of the copied file with the result that build commands were being done twice.
