Build Dependency

• llvm-msvc

Build

git clone --recurse-submodules https://github.com/NewWorldComingSoon/UnknownField.git
cd UnknownField
set LLVM-MSVC-BIN=E:\llvm\llvm-msvc-bin  -> You need to replace your path.
cmake -Bbuild -DLLVM_DIR=%LLVM-MSVC-BIN%\lib\cmake\llvm -DClang_DIR=%LLVM-MSVC-BIN%\lib\cmake\clang
cmake --build build --config Release -- -m
