cmake complains:
```
CMake Error at /usr/lib/llvm-20/lib/cmake/llvm/LLVMExports.cmake:1914 (message):
The imported target "mlir-pdll-lsp-server" references the file
"/usr/lib/llvm-20/bin/mlir-pdll-lsp-server"
but this file does not exist. Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
"/usr/lib/llvm-20/lib/cmake/llvm/LLVMExports.cmake"
but not all the files it references.
Call Stack (most recent call first):
/usr/lib/llvm-20/cmake/LLVMConfig.cmake:370 (include)
CMakeLists.txt:15 (find_package)
-- Configuring incomplete, errors occurred!
```
Workaround: install `mlir-20-tools` and `libpolly-20-dev` as well.
