[RFC] A vision for building the runtimes

How is CMake rigged to build these libs using the just-built Clang? If this functionality is built into the current build system, can you kindly point me to where this is rigged up? Is add_custom_command being used?

Thanks,

It's in llvm/runtimes/CMakeLists.txt.
