From dd62ee376e4cd3018906f7a913a88d2352b637bc Mon Sep 17 00:00:00 2001 From: Brad King Date: Mon, 27 Apr 2020 08:29:52 -0400 Subject: Tutorial: Restore MakeTable.cxx in step 6 In commit c754a3d4b7 (Tutorial: Remove MakeTable.cxx from Steps 5 and 6, 2020-04-23) it was incorrect to remove the file from step 6. The instructions for that step show the addition of a reference to it from the `CMakeLists.txt` file. Each step shows the addition of content to lead to the next step, so removing the file from step 6 was an off-by-one error.
