libchamplain under msys2

[Andrea Zagli <andrea zagli free gmail com>]

hi and thanks for libchamplain

i built libchamplain under msys2  
(http://sourceforge.net/projects/msys2/) but it seems that it doesn't  
work correctly

i only tried the sample from

https://wiki.gnome.org/Projects/libchamplain/documentation

and it doesn't resize correctly and it doesn't zoom with double click  
or scroll mouse button (under linux it works)

may the problem is clutter?

someone can help me?

thanks in advance
