I just commited ( rev 58461 ) a patch which change the name of the generated solution file for a CMake build. (from 'project' to 'LLVM').
This has the consequence that if you use the GUI of MSVC, you will need to manually open to the new solution (the old one isn't deleted but will not be updated anymore). This will also force a full rebuild.
ps: Is it just me or the VS linker crash (Internal error) on some projects when doing a full rebuild? it work the second time through...
