We represent stub libraries, e.g., for CUDA, using imported `SHARED` library targets with only `IMPORTED_IMPLIB`, and no `IMPORTED_LOCATION`, to indicate that the stub file is meant only for linkers and not dynamic loaders. See commit7351d590ee(cmTarget: Add a way to represent imported shared library stubs, 2023-07-17, v3.28.0-rc1~344^2) and commitfc6508921c(cmComputeLinkInformation: Restore soname lookup for non-imported targets, 2023-12-05, v3.28.0~4^2). If a shared library is linked to a stub, it has a `NEEDED` field populated with the `SONAME` found in the stub. When a dependent target links to such a shared library, some linkers want to find a library file on disk and load it to see what symbols it provides. This is necessary for linkers that enforce `--no-allow-shlib-undefined`. On hosts with only the stub library installed, e.g., with only the CUDA toolkit development package, the real runtime library corresponding to the stub's `SONAME` may not even exist, so no `-rpath-link` flag can help linkers find it. Pass the stub library to linkers explicitly so they can find it without searching.
