 commands to a separate file and set CMAKE_PROJECT_INCLUDE to point to it, so
 project() will execute it immediately after initialization.
 
+* After executing the toolchain file, CMake generates and attempts to build

 * 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
