… Windows. (pytorch#159080) See https://cmake.org/cmake/help/latest/command/file.html#path-conversion. Paths stored in environment variables may use `/` or `\` (e.g. on Windows), while cmake-style paths always use `/`. This fixes configure errors like: ``` CMake Error at D:/b/pytorch_main/build/CMakeFiles/CMakeScratch/TryCompile-srhq07/CMakeLists.txt:2 (set): Syntax error in cmake code at D:/b/pytorch_main/build/CMakeFiles/CMakeScratch/TryCompile-srhq07/CMakeLists.txt:2 when parsing string D:\projects\TheRock\external-builds\pytorch\.venv\Lib\site-packages\_rocm_sdk_devel/cmake/;D:/b/pytorch_main/cmake/Modules Invalid character escape '\p'. CMake Error at D:/projects/TheRock/external-builds/pytorch/.venv/Lib/site-packages/cmake/data/share/cmake-3.31/Modules/Internal/CheckSourceCompiles.cmake:108 (try_compile): Failed to configure test project build system. ``` (note the mixed usage of `\` and `/` in that string) Pull Request resolved: pytorch#159080 Approved by: https://github.com/jeffdaily
