I think you'll have to do this.

this exists basically.
The files cmake loads are named <OS>-<tool>-<language>.cmake.
In CMake there are e.g. Generic-SDCC-C.cmake.
This would be "BareMetal" using sdcc.
You can write your own files for your own platforms.
OS and other settings can be set up in your toolchain file.

Are you familiar with cmake cross-compiling support in CMake ?
If not, please get into this, it handles many of the issues you have.
