That looks generally correct, though I think you may need to add clang to the list of LLVM projects to enable (clang-tidy relies on clang and I've never tried building clang-tools-extra without clang before). Also, you shouldn't need to do the install step for local development (so my own setup doesn't set the install prefix). FWIW, I do my development on Windows using Visual Studio and its integrated CMake support, so my CMake settings are going to be a bit different than yours anyway. FWIW, I use `-DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_IDE=ON -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DLLVM_PARALLEL_COMPILE_JOBS=112 -DLLVM_PARALLEL_LINK_JOBS=16`
