cp is sometimes not available on Windows.

Hi, were you able to solve the problem? I have the same error

You can temporarily use the older version v0.4, which doesn't have this issue.

libsql = "0.4.0"

No. The only solution is to use libsql 0.4.0

[milen-denev]

The reason this occurs is because in the build.rs script the developers have put the Linux cp command for copying. I created my own copycat of cp, rust_cp. The repository has compiled binary, put this in any location you want on your windows system, and add Path environment variable, restart the system, and it should work.

I'm also hitting the same problem, calling "cp" directly was obviously going to break the Windows build, does that mean Windows support is not properly tested?
