Mesh network with NOT only MikroTik devices.

Hello. I want to build mesh network on my campus. I chose OpenWRT with 802.11s or batman-adv for existing routers(controlled by students) and RB711 for newly(controlled by our university). But i can’t find any information about implementing any open mesh protocol on RouterOS, B.A.T.M.A.N. or 802.11s. This is real to combine MikroTik’s devices and routers with OpenWRT on board?

Deleted because not related.

MME is “B.A.T.M.A.N. like”, but not compatible
HWMP+ is HWMP like, but not compatible

… this looking to documentation, never tried
