mkdir llvm-install
mkdir llvm-build
cd llvm-build
cmake -DCMAKE_BUILD_TYPE=Release  -DCMAKE_INSTALL_PREFIX=../llvm-install\
        -DLLVM_ENABLE_PROJECTS="clang;lld;clang-tools-extra" \
        -DLLVM_TARGETS_TO_BUILD="X86;ARM;NVPTX;AArch64;Mips;Hexagon;WebAssembly" \
        -DLLVM_ENABLE_TERMINFO=OFF -DLLVM_ENABLE_ASSERTIONS=ON \
        -DLLVM_ENABLE_EH=ON -DLLVM_ENABLE_RTTI=ON -DLLVM_BUILD_32_BITS=OFF \
