... and fix d3d11 specific enum type name GST_CUDA_HAS_D3D is a build time define which indicates whether GstD3D11 library is available or not, but DirectX SDK headers must be available on the build system already. Expose Direct3D related symbols if the build target is Windows (i.e., if G_OS_WIN32 is defined) Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3018>
