@ClausKlein No,
I haven’t found it necessary to use one. I do use a small script to run the CMake command. For me it’s working fine. I’m using the Green Hills MULTI generator to use gbuild to parse the integrate file, generate header files, build the kernel, build the applications, and then integrate everything into a Monolith image, then a custom command to deploy image.
I’m not using Ninja for running the build with the GHS compilers. I pushed some changes that incorporates some of the ideas of #19743. cmake/cmake!4136 and cmake/cmake#20089 make it easy to at least compile a file with Ninja but there would be more work for archiving libraries. Then there would be the custom rules for running the integrate and other commands required for building a monolith image.
