    Pretty much as title says, run something like
```shell
cmake -G Ninja "${LLVM_PROJECT_DIR}/llvm" \
 -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_C_COMPILER=clang \
 -DCMAKE_CXX_COMPILER=clang++ \
  -DCLANG_DEFAULT_LINKER=lld \
 -DCLANG_DEFAULT_RTLIB=compiler-rt \
 -DLLVM_DEFAULT_TARGET_TRIPLE="x86_64-pc-linux-gnu" \
 -DLLVM_TARGETS_TO_BUILD=X86 \
  -DLLVM_ENABLE_PROJECTS='clang;lld' \
 -DLLVM_ENABLE_RUNTIMES='compiler-rt;openmp' \
  -DLLVM_USE_LINKER=lld \
  -DLLVM_CCACHE_BUILD=ON
ninja
```
and get
```console
