Complex Build Scripts Fail with MSVC Targets

[Alexhuszagh]

Summary

When trying to compile a crate with a complex, external build system, MSVC's cl frequently fails, due to unexpected arguments. Another example is #14.

Example

Cargo.toml

[package]
name = "openssl"
version = "0.1.0"
edition = "2021"

[dependencies]
openssl = "0.10"

[features]
default = []
vendored = ["openssl/vendored"]

Building then with cross build --target x86_64-pc-windows-msvc fails.

Error Output

The error output is as follows:
