[Windows Ninja Clang/LLVM] Failed to load GetEngineFactoryXXX function from GraphicsEngineXXX_64d.dll library

[LeSnow-Ye]

Platform: Windows 11

The whole project is basically the same as Samples/GLFWDemo, but linked to DiligentEngine using add_subdirectory.

A: Using Ninja + Clang/LLVM toolchain:

• Vulkan: Successfully built. Failed to run:
  • Failed to load GetEngineFactoryVk function from GraphicsEngineVk_64d.dll library
  • at IEngineFactoryVk* pFactoryVk = LoadAndGetEngineFactoryVk();
• OpenGL: Successfully built. Failed to run:
  • Failed to load GetEngineFactoryOpenGL function from GraphicsEngineOpenGL_64d.dll library
  • at IEngineFactoryOpenGL* pFactoryOpenGL = LoadAndGetEngineFactoryOpenGL();
• DX11/DX12: Successfully built. Runs well.

B: Using Visual Studio 17 2022 + MSVC:

• All: Successfully built. Runs well.

---

Copy GraphicsEngineXXX_64d.dll from B into A: Runs well.

So the problem is that when building with clang, DX11/DX12 works well, but Vulkan/OpenGL fails to get the GetEngineFactory* function from the DLL? This is strange, all factories are implemented identically in all backends.

Yes? I'm new to C++. So I don't know much about what's going on. I just tried these setups. If additional information is needed, please let me know.
