From 7dd1de8a519324e6ec7dbfede1b446980cb5954f Mon Sep 17 00:00:00 2001 From: Oliver Wolff Date: Tue, 1 Mar 2016 13:28:02 +0100 Subject: [PATCH 2/7] 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.
