I'm afraid that we are miscommunicating. The first paragraph quoted on
this message is a question by someone who clearly asks if is it possible
(i.e. technically achievable) to execute a CMake build from another. The
answer is yes, as demonstrated by how tablegen is managed while
cross-compiling by the LLVM CMake scripts. AFAIK solving the compiler-rt
case would be achieved by a similar (not identical, but similar)
