Best version of Ogre to build this against?

[Slamy]

Hello. I've tried to build this project but I can't find a version of Ogre to be compatible with this project.
It should be 2.1 but I get compiling errors. So maybe there are multiple revisions of ogre-next which call themselves 2.1.
It would be helpful to know the commit revision which would suit this project.

vs2019 x64, win10, hlmsedtior ,ogre-next2.1 can compile well
