Subject: [PATCH 68/83] Move the addition of -Wno-deprecated-copy to CGAL_Qt5
 setup

That way:
  - that will work, even if CGAL CXX_FLAGS are copied (when hte CMake
    options `CGAL_DEV_MODE` or `RUNNING_CGAL_AUTO_TEST` are `ON`),
  - that will affect all CGAL Qt5 demos at once.

```

The warning is because an uninitialized `optional` is copied (in a
`push_back()`). The fix is to use `emplace_back()` to construct it
directly in the vector, instead of copying it.
