I have found a fix to my problem. It was actually much easier than I was making it out to be. The variable `CMAKE_<LANG>_LINK_EXECUTABLE` does not _need_ to be defined before calling `project()` as I was attempting to do by defining it as a `Platform/` or in the toolchain file. It can actually be defined in the `CMakeLists.txt` file, _after_ the call to `project()`.

Defining this rule variable before the call to `project()` might be possible in a `Platform/` file or some other way, but I had no luck with that approach.
