<pre>
    It's taken me a long time to get to this point (due to a very hard-to-diagnose [bug](https://github.com/llvm/llvm-project/issues/58541) involving symlinks), but [building](https://github.com/conda-forge/compiler-rt-feedstock/pull/53) compiler-rt as for LLVM 14 does not work anymore. In particular, just a very simple invocation of

```
mkdir build
cd build
cmake [options] ../compiler-rt 
cmake build .
cmake install .
```

does not work anymore - nothing gets built or installed.

After digging around a bit in some of the associate CMake [files](https://github.com/llvm/llvm-project/blob/llvmorg-15.0.4/compiler-rt/cmake/Modules/AddCompilerRT.cmake), I tried to exchange the last two lines with
```
cmake --build . --target compiler-rt
cmake --install .
```
since compiler-rt [should](https://github.com/llvm/llvm-project/blob/llvmorg-15.0.4/compiler-rt/cmake/base-config-ix.cmake#L21) contain everything (sidenote: CMake throws up over `cmake build . --target xxx` without the dashes before `build` - but 🤷)

This seems to be building most libraries, in particular

But fails upon installation:
```
cmake --install . 
-- Install configuration: "Release"
CMake Error at lib/stats/cmake_install.cmake:36 (file):
  file INSTALL cannot find
  "D:/bld/compiler-rt-packages_1667989486494/work/build/lib/windows/clang_rt.stats-x86_64.lib":
  File exists.
```

The problem does not appear on linux/osx.
