I'm super interested in CMake support for modules (both Clang's back-compat
modules (with modulemaps) and C++ standard modules) - I'll be talking at
the developer meeting about some of the issues around Modules TS build
system impact (following on from the talk I gave last year on modular code
generation) & honestly would love to have a CMake prototype/demo (for clang
back-compat modules and/or modules TS modules), with the intent to get
something usable for self-hosting one form of explicit modules or another
(modular code generation, etc) with the LLVM build, but not sure I really
have the CMake skills to pull that off in time.
