Problem with building mogre from source

Hi everybody,In tutorial there is a step like this
Before we begin you need to unzip the OGRE dependencies in the ogrenew folder but DONT OVERWRITE OIS.lib, OIS_d.lib or any other .dll related to OIS. The reason is that MOGRE uses a modified version of OIS and overwriting it with the one in the dependencies would cause severe problems during this process!
but I can not find any OGRE dependencies zip in ogrenew folder , is there any other mean with these?

Thanks any help!

I'am so sorry about my poor English!

There are precompiled dependencies on this page http://www.ogre3d.org/download/source
