// Lets this crate's tests run without manual setup when the `shim` feature
// links the Noesis library. noesis_runtime's build script publishes the
// resolved Bin/<platform> path as DEP_NOESIS_LIB_DIR (`links = "Noesis"`); it is
// unset without `shim` and under DOCS_RS, when nothing links Noesis.
//
// Linux bakes that path into the rpath. Windows has no rpath, so Noesis.dll is
// copied next to the test binaries instead.
