put the previous commit behind cmake option ZIG_PREFER_CLANG_CPP_DYLIB Without this, building from source caused: CommandLine Error: Option 'mc-relax-all' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options This is due to LLVM static libs compiled in multiple times. But without the LLVM static libs on the linker line, it caused undefined symbol linker errors. So our hands are tied. Homebrew users will have to specify `-DZIG_PREFER_CLANG_CPP_DYLIB`.

include(FindPackageHandleStandardArgs)
cmake: address new warnings from cmake-3.17 Match package-name case from CMakeLists.txt . New warning sample: The package name passed to `find_package_handle_standard_args` (LLVM) does not match the name of the calling package (llvm). This can lead to problems in calling code that expects `find_package` result variables (e.g., `_FOUND`) to follow a certain pattern.
