On the Windows platform, when using MSVC to compile, if both `openmp` and `flang` are specified in `LLVM_ENABLE_PROJECTS`, an error occurs during the build:
```bash
ninja: error: 'projects/openmp/runtime/src/omp_lib.F90', needed by 'include/flang/omp_lib.mod', missing and no known rule to make it
```
If I remove either `openmp` or `flang` from `LLVM_ENABLE_PROJECTS`, it can build successfully in either case.
```bash
git log -1
