From d99b3c451b31b935be914e6238fa631dba0aafc6 Mon Sep 17 00:00:00 2001 From: Oliver Wolff Date: Mon, 10 Dec 2018 08:33:14 +0100 Subject: ANGLE: Dynamically load D3D compiler from a list If the default compiler cannot be found, load it from a list of DLL names, including a non-versioned proxy DLL provided by Qt. On Desktop Windows, the default compiler can also be specified by an environment variable, QT_D3DCOMPILER_DLL.
