That would mean a lot of duplication for just redefining a particular value. Each compiler will have likely a way too handle the definition of multiple flags with the same purpose and based on that prepending or adding could be performed internally. ________________________________ Van: Brad King <brad.k...@kitware.com> Verzonden: woensdag 23 augustus 2017 17:33:25 Aan: maikel van den Hurk CC: cmake-developers@cmake.org Onderwerp: Re: [cmake-developers] Extend CMAKE_<LANG>_FLAGS(_<CONFIG>) from a CMake Toolchain

If you want to change the default flags instead of only adding (prepending) to them then you need to set all the flags by setting the cache entry directly. A toolchain file that wants such control should be setting all the flags anyway. -Brad
