"""Invoke cargo with the correct Rust target on Windows cross-compilation.

Works around three issues: GYP's MSVS generator mangles executable names in
host-toolset actions (breaking direct cargo calls), GYP cannot set different
variable values per toolset, and cargo's output directory layout uses Rust
target triples while MSBuild expects platform names (x64/arm64). This script
reads MSBuild's $(Platform) to select the right Rust target and copies the
built library to a path MSBuild can resolve per-project.
