You can set bindgen to only use the .dll instead of requiring both the .lib and .dll
via:
let bindings = bindgen::Builder::default() .header("inc/wrapper.h") .clang_arg("-v") .dynamic_library_name("SymCryptLib")
This will cause errors with unresolved errors for pub static variables exported from SymCrypt. Investigate if there is a way to circumvent this so that we can only rely on the .dll
