BufferOverflowK.lib: unresolved external symbol __guard_fids_table

[Yurii Cherkasov]

I'm compiling a huge open-source project (Actually Virtualbox 6.0.4 Open Source Edition)
https://www.virtualbox.org/browser/vbox/trunk
and getting stuck with the following error (formatted for readability):

__guard_fids_table is a part of Microsoft anti-malware Control Flow Guard API, introduced in Windows 8.1. As far as I know, it requires Visual C++ version 14.0 (which is MSVS 2015 Update 3), however, it's still lack of official documentation of this API, so I'm not 100% sure.

Also, there's literally no official documentation how to build Virtualbox 6.*, so there I'm also not sure, is that a bug of their build system, or some additional configuration required, or different build toolchain required.

Visual C++ 2010 is still officially supported compiler for Virtualbox OSE project, because of massive backward compatibility of COM interfaces, all my attempts to migrate at least to 2013 failed. I suspect that VC++ 10.0 is a wrong compiler for this piece of project, but it's again just a guess. I'll appreciate any directions of further investigating how to solve the problem
