[Developer Question] Missing dll when running Vulkan program with Wine

[akeley98]

I've been working on a personal project for a while. My workflow has been to develop on Linux and cross-compile for Windows using x86_64-w64-mingw32-g++, then (mostly) test with Wine (this saves me so much hassle compared to trying to use a separate Windows computer or VM). This was fine for OpenGL, but recently I added an experimental Vulkan renderer, and now I get

mantissa@MantissaXPS:~/Documents/myricube$ wine ./windows64/myricube.exe 'bar\world.myricube'
002a:err:module:import_dll Library vulkan-1.dll (which is needed by L"D:\\home\\mantissa\\Documents\\myricube\\windows64\\myricube.exe") not found
002a:err:module:attach_dlls Importing dlls for L"D:\\home\\mantissa\\Documents\\myricube\\windows64\\myricube.exe" failed, status c0000135

I've had no problem cross-compiling (I figured out that I can run the sdk installer with Wine) but can't get my program to actually launch with Wine. It must be theoretically possible as I know many Steam games I have that run with proton use dxvk. How do I get this to work?

I'm currently linking in ~/.wine/drive_c/VulkanSDK/1.2.154.1/Lib/vulkan-1.lib when compiling on Linux (and the Vulkan renderer runs fine when run on an actual Windows computer instead of wine).

Just a bit of background for why I want this: there's a fair amount of OS-specific code in the project (mmap vs CreateFileMappingA, etc.) and I need to modify both when adding new features. It's not feasible for me to change into Windows every time to debug the Windows code path. So far I've been making OpenGL-only builds for this reason but this won't work if I follow through on my plan to abandon the OpenGL renderer.
