aea2734
aea2734Patch CMakeLists to install CMake modules to share/llvm instead of lib/cmake/llvm. This works better than vcpkg_fixup_cmake_targets because other parts of the LLVM build system really want all the variables set correctly. Also set other options to prevent creation of any bin/* instead of removing them after the fact, for the same reason.
