I don’t see why the runtimes wouldn’t be included in this, especially when using the runtimes build which already supports building multiple configurations of libc++ from a single LLVM CMake invocation which in turn runs CMake for the runtimes multiple times. In fact, I think runtimes is basically the only place where we can currently cleanly handle building with different options. > While I'm very sympathetic to the use case, it looks like this is working > against the design of CMake. The way Compiler-RT builds for Darwin is certainly against the design of CMake, but I don’t think the same is true for how the runtimes build works. I think the general idea of configure LLVM once, define multiple different “distributions” to get different groups of targets that you can install into different root directories and package for separate installation makes a lot of sense and is useful even if it doesn’t handle distributions that have different configurations.
