ANGLE is based on the DirectX SDK. While Mingw-w64 ships the appropriate headers, it's apparently missing the runtime library (d3dcompiler AFAIR) and the fxc.exe effect compiler from the Direct X SDK, used at compile time. So yes, right now you've to either install a Direct X SDK, or pass -opengl desktop .

(I'm also worried that these dependencies break crosscompiling... we should really consider including pre-generated files here instead of relying on fxc.exe being available at compile time).
