Problems with chocolatey cmake install (.bat) in windows client.

Reported in: http://forum.biicode.com/t/bii-configure-reports-cmake-not-found-but-cmake-is-installed/392/3 by @kirkshoop

It seems that .bat file has some problem for being launched with the current implementation.

@Manu343726 also uses chocolatey packages on win, could you please have a look?.
