Traditional MSVC linking of a large C++ project (say, Chrome or Unreal Engine) can take minutes. LLD reduces that to seconds.
set CC=clang-cl set CXX=clang-cl CMake is the universal bridge. Create a CMakeLists.txt and build: windows clang
mkdir build && cd build cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl cmake --build . Note: clang-cl is a drop-in driver that accepts most MSVC cl.exe flags. This makes porting existing build scripts trivial. The single best reason to use Clang on Windows is LLD . Traditional MSVC linking of a large C++ project
