build failure due to missing "utf8.h"

[Fergus Cameron]

Noted a couple of previous posts on the subject but none of the actions resolved the issue for me.  I'm sure it must be something simple but, currently at a loss as to how to debug this further.  'cmake .' appear to complete successfully (no error file in the 'CMakeFiles') and './acprep update' then bombs with the following

Tried cleaning the repository and then simply checked out a fresh copy; all with the same result.  Certainly I have the 'system.hh' and no 'utf8.h'.

Attaching the CMake log.

Pointers / thoughts, greatly appreciated.

Try: git submodule update --init

The utf8.h file is within a submodule in the lib directory.
