It is *not* going to be used by QEMU developers, because QEMU developers have conflicting requirements: * Not getting in the business of maintaining a distribution of all their dependencies (glib, pixman, etc.) * Not wanting to maintain multiple build systems both of which are non-negotiable. What you might do is use the configure script and the ninja backend to build all generated sources (produced by either configure, meson or make); then copy those generated file over to a new build directory, invoke meson again with the xcode backend, and distribute the result so that it is ready to build from source using xcode. The resulting distribution is not appropriate to develop QEMU, but it would be okay to install it and even for some simple debugging. The above approach still doesn't solve the problem of building glib and friends as part of the same xcode project. Perhaps this can be fixed by patching the xcodeproj that Meson generated. The scripts needed to do so should be relatively stable and can certainly be included in the upstream QEMU sources. You can't expect that other people will test them unless you also include them somehow in our CI, but just having the scripts would be a start.
