Building 3.13.4 on Windows using Visual Studio 2022 17.6.2 and OneAPI 2023.1

[loopless]

I have having a difficult time building Embree 3.13.4 on Windows VS 2022 17.6 due to include file conflicts

From what I can see, platform.h includes "memory" which ultimately includes "cstring" which includes "string.h" but the compiler finds the Embree "string.h" and everything falls apart.

Hi, unfortunately I could not reproduce this.
I was using a clean windows 11 installation using VS 2022 with the Intel OneAPI 2023.1 and cmake 3.27.0

inside embree-3.13.4 folder

cmake -B build -G "Visual Studio 17 2022"
cmake --build build
