Found it: https://cmake.org/pipermail/cmake/2013-March/054161.html Looks like something Bill Hoffman suggested years ago. I still don't remember why I started using it, it was definitely to work around some sort of issue. What is the proper, public API solution that gives identical functionality? Should I be using `CMAKE_C_COMPILER` instead, and appending to it as a string from my toolchain file?
