Pulled from Crates.io, nuklear-sys build script panics

[khionu]

When pulling from Git, there is no issue, it is exclusively when nuklear-sys is imported from a Cargo repository.

Panic with trace: https://gist.github.com/khionu/cac71a3176ed42840caa79b53af26bbd

OS: Win 10 Pro (1903)

The stacktrace shows problems with pulling the Nuklear C library via Git to the Cargo registry folder. Can you please go to C:\Users\Khionu\.cargo\registry\src\github.com-<hashed> and delete all the nuklear-* folders, and try building nuklear-test again?
