You are misinformed. The LLVM CMake scripts can build LLVM/Clang as
shared libraries since almost day one.

If you are thinking of Windows, well, there is a fundamental limitation
there, not an issue with CMake. Autoconf has a hack for building LLVM as
a single, monolithic dll while using MinGW. That hack can be easily
replicated on CMake. As for Visual Studio, autoconf is pretty useless,
so no dll's there in any case until someone sprinkles the LLVM C++
sources with the necessary declarations.
