Unresolved external symbol errors while linking project

[disarray2077]

This issue seems related to #2123, but this time I'm getting linker errors when I try to compile the project.

Here's a sample of the errors:

LuaTinker__.lib(LuaTinker_StackHelpers_StackHelper@LuaTinker_Tests.obj) : error LNK2019: unresolved external symbol "public: static int bf::LuaTinker::Tests::TestMemVar::Actor::sBfTypeData" (?sBfTypeData@Actor@TestMemVar@Tests@LuaTinker@bf@@2HA) referenced in function "private: static void __cdecl bf::LuaTinker::StackHelpers::StackHelper::GetBestLuaClassName<struct bf::LuaTinker::Tests::TestMemVar::Actor>(class bf::LuaTinker::LuaTinkerState *,class LuaTinker::System::String *)" (??$GetBestLuaClassName@UActor@TestMemVar@Tests@LuaTinker@bf@@@StackHelper@StackHelpers@LuaTinker@bf@@CAXPEAVLuaTinkerState@LuaTinker@bf@@PEAVString@System@2@@Z)

I tried to create a minimal reproduction for this but haven't been able to isolate the issue yet. So the full project that has this problem is available here: https://github.com/disarray2077/LuaTinker-Beef/tree/linkerissue

The specific line that triggers the linker errors is here: https://github.com/disarray2077/LuaTinker-Beef/blob/b362a9fdeb21ef9e3f249264f3f33b2922cec2aa/src/StackHelpers/StackHelper.bf#L87

Commenting out that line allows the project to compile successfully.
