From a85ea41fd18cb6521655e0fceb58b2b8ce23b563 Mon Sep 17 00:00:00 2001 From: Shoaib Meenai Date: Wed, 13 Dec 2017 21:12:37 +0000 Subject: [PATCH] [cmake] Explicitly set VS 2017 compatibility When cross-compiling using clang-cl 5.0 (which is currently the latest stable release of the compiler), the default MS compatibility level is set to VS 2013, which is too low to build LLVM. Explicitly set the compatibility level to VS 2017 to support cross-compiling LLVM for Windows using clang-cl 5.0. This will be a no-op when using clang-cl 6.0 and above, where the default MS compatibility level is already VS 2017.
