I'm missing a `tar -xf` after the `wget`, but with that in place, it builds on my Ubuntu system.

Does Arch have its own packaging of LLVM? Which packages do you have installed?

The first thing the build does on my system is to copy the clang headers from `${LLVM_LIBRARY_DIR}/clang/${llvm_ver}/include`, so it could be that the headers are missing on your system.

Also, it might be a good idea to use `-DCMAKE_PREFIX_PATH=/usr/lib/llvm-13` to be more specific with LLVM version, but I don't know what the library layout looks like on Arch, so maybe that's not workable there.

I put some `MESSAGE` in the CMake for debugging purposes:
```
-- LLVM_LIBRARY_DIR /usr/lib
-- CLANG_INCLUDE_DIRS /usr/include
-- clang_headers_src /usr/lib/clang/13.0.0/include
```
In `/usr/lib/` are all the `/usr/lib/libLLVM*` and `/usr/lib/clang/13.0.0/include` are all the Clang include files.

I wonder if `make -d` gives any additional information?

`make -d` not much:

Found a workaround. If I change the CMake generator to Ninja with `cmake -G Ninja`, it builds without issue. Maybe, it's a CMake bug.
```
$ cmake --version
cmake version 3.21.4
```

Closing this issue, as there is no clear indication it's an IWYU issue. Thanks!

It would be interesting to run `make` under `strace -f`, to try to figure out what operation got "Access denied".
