My terminology might be off, but:
* most of this function adds some specific to a particular hardware _target_
(i.e. AMDGPU),
* `addDependentLibs` is something linked to specific to a particular _platform_
(i.e. MSVC/Windows).
My suggestion:
* keep `addDependentLibs` as an independent hook,
* rename `addTargetSpecificMLIRItems` as `addAMDGPUSpecificMLIRItems` (we can
rename this later if people want to add support for other targets).
@jsjodin - is that consistent with what you had in mind?
