I remembered that there was an MR that wanted to add dxcore for MinGW, but I don't personally use MinGW myself.

I tried adding the template wrappers using cpp_quote but the built header had them outside the interface block.

```

    local,
    object,
    uuid(526c7776-40e9-459b-b711-f32ad76dfc28),
]
interface IDXCoreAdapterList : IUnknown
{
    HRESULT  GetAdapter(uint32_t index, REFIID riid, [out, iid_is(riid)] void **ppv);
    uint32_t GetAdapterCount();
    BOOL     IsStale();
    HRESULT  GetFactory(REFIID riid, [out, iid_is(riid)] void **ppv);
    HRESULT  Sort(uint32_t num_preferences, const DXCoreAdapterPreference *preferences);
    BOOL     IsAdapterPreferenceSupported(DXCoreAdapterPreference preference);

cpp_quote("#ifdef __cplusplus")
    cpp_quote("template<class T> HRESULT STDMETHODCALLTYPE GetAdapter(uint32_t index, T **ppv)")
    cpp_quote("{")
    cpp_quote("    return GetAdapter(index, IID_PPV_ARGS(ppvAdapter));")
    cpp_quote("}")
    cpp_quote("template <class T> HRESULT GetFactory(T **ppv)")
    cpp_quote("{")
    cpp_quote("    return GetFactory(IID_PPV_ARGS(ppvFactory));")
    cpp_quote("}")
    cpp_quote("#endif")
};
```
Resulted in:

```
#ifdef __cplusplus
template<class T> HRESULT STDMETHODCALLTYPE GetAdapter(uint32_t index, T **ppv)
{
    return GetAdapter(index, IID_PPV_ARGS(ppvAdapter));
}

{
    return GetFactory(IID_PPV_ARGS(ppvFactory));
}

        uint32_t num_preferences,
        const DXCoreAdapterPreference *preferences) = 0;

virtual BOOL STDMETHODCALLTYPE IsAdapterPreferenceSupported(

};
```
I didn't see a way around it without manually hard-coding the lines for C++, which was not worth it at that point.
