[HIPIFY] Linking fails when LLVM libraries were compiled as shared library.

Problem Description

When trying to link HIPIFY on Arch linux using LLVM from the arch package repository I get the following error when linking:

This is because on Arch the LLVM libraries are compiled with LLVM_LINK_LLVM_DYLIB=ON to one shared library llvm.so instead of multiple static ones.
The same goes for clang.

For LLVM it is recommended in llvm/llvm-project#34593 to use the "llvm_config" macro to get the correct library names for a list of modules.

For clang it seems one could use the clang_target_link_libraries function from the Clang package for cmake to get the correct library names for a list of modules.

Operating System

Arch Linux

CPU

Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz

ROCm Version

ROCm 6.0.0

ROCm Component

HIPIFY

Steps to Reproduce

1. Compile LLVM with LLVM_LINK_LLVM_DYLIB=ON.
2. Try to compile and link HIPIFY using that LLVM. For example by pointing CMAKE_PREFIX_PATH to the according LLVM directory.

ROCm HIP and HIPIFY tools do not support Arch Linux yet.
