build failed on windows: unknown escape sequence

[prvnprk]

windows uses "\" in paths. that is causing problems when i try building it using zig build.

here is the error message:

Hi @prvnprk, thanks for sharing these details and proposing a fix; however, I'm not able to reproduce this build issue on my windows machine or the windows CI/CD build agent on GitHub.

Can you share some more information about how to reproduce the issue? Which version of Zig are you using, which version of zig-luajit, and are you able to build and run any of the examples in zig-luajit?
