FFI can work - P/Invoke with C# for example doesn't care if you're cross compiling or not, but it comes at the cost of needing a definition of the interface in your code. Windows makes cross compiling work by shipping the libs for each of the architectures in the SDK. I think that's quite reasonable for macOS since Apple controls the SDK, but it's always seemed to be a mess on Linux. Disclaimer: I work at Microsoft on Windows but I have tried cross compiling code on both Windows and Linux in the past and I've always found it painful on Linux.
