Clang toolchain

The compiler is stored at Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v16_clang-9.0.1-centos7/x86_64-unknown-linux-gnu/. Or something similar, depending on Unreal Engine version. We call this the "compiler directory". The standard library is stored at Engine/Source/ThirdParty/Linux/LibCxx/lib/Linux/x86_64-unknown-linux-gnu/. We call this the "LibCxx" directory.

Different versions of Unreal Engine use different versions of Clang:

UE4 Version    Toolchain
4.27           v19_clang-11.0.1
4.26           v17_clang-10.0.1
4.25           v16_clang-9.0.1
4.23           v15_clang-8.0.1
4.24           v15_clang-8.0.1
4.22           v13_clang-7.0.1
4.21           v12_clang-6.0.1
