Install recent versions of MinGW, CMake and Ninja. Make sure everything
is reachable through PATH environment variable.

Let's suppose that LLVM sources are installed in C:\LLVM and Clang in
C:\LLVM\tools\clang

Execute this commands on a Windows command prompt and you are done:


mkdir \buildLLVM

cd \buildLLVM

cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=c:/llvm_installed ../llvm

ninja

ninja install


Be sure that ../llvm is indeed the path to the LLVM sources from the
build directory.

You can change CMAKE_BUILD_TYPE to Debug, depending on your usage. Last
time I tried (long time ago) it was not strictly required to install
Clang to use it.
