Can't build EOS plugin

Hello there. I am trying to use EOS plugin from Redpoint Games (free edition) for my project. Plugin itself isn’t compatible with my engine (engine is built from source) and I am trying to rebuild it myself. When I build it I get lots of errors exactly like this but with different .dll files in the end of path:

LINK : error LNK2001: unresolved external symbol _DllMainCRTStartup

C:\Users\User\Desktop\UnrealEngine-release\OnlineSubsystemRedpointEOS\HostProject\Plugins\OnlineSubsystemRedpointEOS\Binaries\Win64\UE4Editor-RedpointEOSTests.dll file:C:/Users/User/Desktop/UnrealEngine-release/OnlineSubsystemRedpointEOS/Plugins/OnlineSubsystemRedpointEOS/Binaries/Win64/UE4Editor-RedpointEOSTests.dll : fatal error LNK1120: 1 unresolved externals

I went to that files and inside them wasn’t much information about line _DllMainCRTStartup. Trying to add _DllMainCRTStartup line to them and copying same files from other places didn’t help. Did you had a similar problem? How did you resolve them? What you think I should do in order to successfully rebuild EOS plugin from Redpoint Games? Thanks in advance
