Broken Enzyme_LLVM_BINARY_DIR environment variable

After having run `brew install enzyme` on WSL, the following CMakeLists.txt fails

```
cmake_minimum_required(VERSION 3.20)

find_package(Enzyme REQUIRED CONFIG) # must install enzyme & lld through Brew / Spack
set(CMAKE_CXX_COMPILER "${Enzyme_LLVM_BINARY_DIR}/bin/clang++")
```

With the following error:

> CMake Error at CMakeLists.txt:7 (project):The CMAKE_CXX_COMPILER:

>

My correct LLVM path is `/home/linuxbrew/.linuxbrew/Cellar/llvm/22.1.2`.

Is this a small bug with Enzyme or an issue with how I have installed it?
