Issue with Enabling Shaderc, D3D11, and Vulkan Features in MPV Cross Compilation on Ubuntu using Meson

[Windev2024]

mpv-player/mpv#14389

System Details:

Host OS: Ubuntu 22.04
Target OS: Windows (cross-compiling)
Cross-Compiler: MinGW (x86_64-w64-mingw32)
Description:
I am following the steps outlined in the MPV documentation for cross-compiling on Windows: MPV Compilation Guide. I successfully built 32-bit and 64-bit versions of MPV, and the standalone MPV is able to play. However, I need to add full-fledged features, and I am encountering issues enabling certain features.

Meson Setup Command:
meson setup --wrap-mode=forcefallback -Ddefault_library=static -Dprefer_static=true \ -Dc_link_args='-static' -Dcpp_link_args='-static' \ -Dffmpeg:default_library=static -Dffmpeg:tests=disabled -Dffmpeg:programs=disabled -Dffmpeg:sdl2=disabled -Dffmpeg:vulkan=auto \ -Dlcms2:fastfloat=true -Dlcms2:jpeg=disabled -Dlcms2:tiff=disabled \ -Dlibusb:tests=false -Dlibusb:examples=false -Dlibplacebo:demos=false \ -Dlibplacebo:lcms=enabled -Dlibplacebo:shaderc=enabled -Dlibplacebo:d3d11=enabled \ -Dvulkan=enabled -Dd3d11=enabled -Dxxhash:inline-all=true -Dxxhash:cli=false \ -Ddrm=disabled -Dlibarchive=disabled -Drubberband=disabled -Dwayland=disabled \ -Dx11=disabled -Djavascript=enabled \ --cross-file /home/x86_64-w64-mingw32.txt build
