Allow space character in pathname during build

[Martin Fischer <martinfischer8@xxxxxxxxxxx>]

Hi,

during build on my Windows systems I noticed that generation of Doxygen 
documentation doesn't work if the pathname includes space characters. 
This patch solves the situation

This is the first time sI submit a git patch via email. So please let me 
know if anything is wrong.

Regards
Martin
