[AD] building trunk with cmake on windows with mingw

[Thomas Fjellstrom <tfjellstrom@xxxxxxxxxx>]

After managing to get all of the dependencies sorted, all the makefile does 
now is shell out to cmd.exe 5 times and sits there. I tried changing SHELL to 
sh.exe but all of the paths use \s which of course doesn't work with sh.exe 
from MSYS.

So what am I supposed to do exactly? I've messed something up no doubt...
