Missing header `llvm/IR/LegacyPassManager.h` after build

IR & Optimizations
,
#1

Hi, I’m trying to build llvm on windows. My build steps are:

  1. download source from https://codeload.github.com/llvm/llvm-project/zip/refs/tags/llvmorg-13.0.1
  2. cd llvm-project-llvmorg-13.0.1 && mkdir build && cd ./build
  3. cmake ../llvm -Thost=x64 -DLLVM_ENABLE_PROJECTS='clang'
  4. using Visual Studio 2022 to open the generated LLVM.sin and press Build - Build solution

After successful build, I can’t find llvm/IR/LegacyPassManager.h in ./build/include file, Did I miss some settings?

I’m not familiar with building on Windows but that header is in the source tree rather than in the build dir

thanks. header is under the llvm directory and llvm-config can help me to locate it.
