I’ve done the same thing for a ‘project’ ‘written’ in assembly language. Again, it just kinda works, with the caveat that the output messages are less then perfect:

```auto
$ CMAKE_TOOLCHAIN_FILE=../xmos_cmake_toolchain/xmos_toolchain.cmake cmake -B build && cmake --build build
-- The ASM compiler identification is unknown
-- Found assembler: /usr/local/bin/XMOS/XTC/15.1.0/bin/xcc
System is unknown to cmake, create:
Platform/XMOS to use this system, please post your config file on discourse.cmake.org so it can be added to cmake
