The "CMAKE_<LANG>_COMPILER" variables are not used for compiling GHS Multi projects. The GHS build tool gbuild handles those kinds of details. You do need to set GHS_TARGET_PLATFORM and specify the target architecture so that a correct GHS Multi project for your target can be built. You can inspect the GHS example projects delivered to you as part of your GHS installation to determine those values. Usually its something like "arm" and "integrity", which is one of the reasons those were chosen as the default. I'd highly recommend reading the GHS manual and looking at the example projects to understand how a GHS Multi project works if you are not already familiar with it. -- F
