crt static link error

[bigdogs]

Hi,

I compile yara rust with

[target.'cfg(all(windows, target_env = "msvc"))']
rustflags = ["-C", "target-feature=+crt-static"]

yara = { version = "0.13.0", features = ["vendored", "bundled-4_1_3"] } 

failed with the following errors

set flags by RUSTFLAGS env seems OK
