commands to a separate file and set CMAKE_PROJECT_INCLUDE to point to it, so
project() will execute it immediately after initialization.

+the toolchain script (which is why you'll see commands executed multiple times)

* There is no way to use multiple toolchains (PS1 + host) in a single project,
even if you use add_subdirectory() to execute multiple project files (which,
confusingly, adds their targets to the parent project rather than treating them
