2. cd build
3. cmake .. -G Ninja -D CMAKE_BUILD_TYPE="Debug" -D CMAKE_CXX_COMPILER="C:/Program Files/LLVM/bin/clang++.exe" -D CMAKE_C_COMPILER="C:/Program Files/LLVM/bin/clang.exe" -D CMAKE_RC_COMPILER="C:/Program Files/LLVM/bin/llvm-rc.exe
4. ninja

Some observations

• Debug builds on Windows are slow to run. Thus, configure a release build:
  • cmake .. -G Ninja -D CMAKE_BUILD_TYPE="Release" -D CMAKE_CXX_COMPILER="C:/Program Files/LLVM/bin/clang++.exe" -D CMAKE_C_COMPILER="C:/Program Files/LLVM/bin/clang.exe" -D CMAKE_RC_COMPILER="C:/Program Files/LLVM/bin/llvm-rc.exe"
