<pre>
    I was setting up my workspace to use a pre-compiled installation of the MLIR project. The rest of the tools are working fine as far as I have tested. The only issue I saw was with the executables for `tblgen-lsp-server` and `mlir-pdll-lsp-server` which I discovered while setting up LSP support for neovim.

**TL;DR:** When installing the MLIR project and building as shared libraries, the libraries `libMLIRPdllLspServerLib.so` and `libTableGenLspServerLib.so` aren't installed. The same behaviour is observe when packaging the project with `cpack`.

# Steps to reproduce

Checkout to the current latest stable tag at `llvmorg-18.1.5`.

## Build

I followed more or less the same instructions as [the official documentation](https://mlir.llvm.org/getting_started/). I only added where it should be installed and that I need to build shared libraries to reduce the size of the resulting installation due to space issues.

## Post compilation scenario


The executables are built in `build/bin/` and the libraries `libMLIRPdllLspServerLib.so` and `libTableGenLspServerLib.so` are built in `build/lib/` and the binaries run just fine.

## Post installation scenario



The executables can't find the `.so`s because they aren't installed.

## Packaging scenario


Packaging using CPack also shows the same behaviour. The same libraries are absent from the package but other libraries are present.
