[yocto] Using yocto as a build system

[mamta0925 at yahoo.com]

Hi,

Apologies if these are basic questions but thought this will be the best place to find answers to the point

So our requirement is to build open source packages in Linux, windows and Mac on a build system. Currently we have an internal build system which is quite cumbersome to manage. Hence we are looking for outside options

Given our situation, is Yocto our best solution? Does it even provide for building windows and Mac open source packages? 

Thanks,
Mamta
