[LyX/master] Cmake doc creations: Setting environment PYTHONIOENCODING

[Kornel Benko]

commit a68ef98103497ada9d53877f4ee93414c514777b
Author: Kornel Benko <kor...@lyx.org>
Date:   Tue Oct 17 12:28:36 2017 +0200

    Cmake doc creations: Setting environment PYTHONIOENCODING
    
    This should force the python executable to use the desired encoding.
    The command is moved to a wrapper script to be able to set the environment
    at make-run-time.
