Rust support?

[kkimdev]

I'm trying to generate Oryol Rust binding and code in Rust. What would be the most proper way to integrate Rust compilation (Cargo)?

External build systems aren't really supported right now, you may be able to workaround with a custom verb that will prepare the rust library and trick fips to use the generated output or a fips-generator.

In any case, this is how one would integrate Rust in a CMake project: https://stackoverflow.com/questions/31162438/how-can-i-build-rust-code-with-a-c-qt-cmake-project

There are other issues related to external build systems #140 and #124. I believe that a simple support to CMake ExternalProject could be done in a simple way and integrating Rust can be easy without adding too much code (as rustup and cargo will do the heavy part).

I learned about CMake Rust Language Support recently, and tried to wrap a simple-to-use module fips-rust around it.

Right now, it only allows to add a Cargo project as a static library, so that it can be conveniently linked with fips_libs() and called from C/C++ code.

I did not try yet to link other fips libraries to a Rust project. That's probably the difficult part.
