[llvm-dev] How to Switch to Static Runtime and Enable C++ Exceptions?

I ran this command "cmake -S../llvm -G"Visual Studio 16 2019" -Thost=x64 -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_BUILD_TYPE=Release -DCMAKE_MSVC_RUNTIME_LIBRARY=MT -DCMAKE_CXX_FLAGS="/permissive- /EHsc /std:c++17 /O2 /MT /D_SILENCE_ALL_CXX_DEPRECATION_WARNINGS" -DLLVM_ENABLE_RTTI=On -DLLVM_ENABLE_EH=ON -DCMAKE_CXX_STANDARD=17 -DPYTHON_HOME=C:/Users/Osman/AppData/Local/Programs/Python/Python38 -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;lld;lldb;libcxx;libcxxabi"".  But I still get "Using Release VC++ CRT: MD", and also the CMake warning: "CMake Warning at utils/benchmark/CMakeLists.txt:244 (message):
  Using std::regex with exceptions disabled is not fully supported".

Please help.
