-- Detect GHS compiler and version Detect ARCHITECTURE_ID for PPC / ARM / 86 targets Detect PLATFORM_ID for Integrity and Integrity178 platforms Using defines specified in the documents for the compilers: 201416 PPC / 201754 ARM / 201714 86 -- Fallback C/CXX compiler ID to GHS if not otherwise detected and using GHS MULTI generator Works around issue with some GHS compilers not setting __ghs__ compiler define -- Tweak Compiler ID checking so major id of 002017 is not replaced with 217 -- Prefer try_compile() library targets when testing for working GHS compilers -- Avoid CMake errors if reading past end of file for checking if file is PE executable
