+# sibling PluginV2 are two SEPARATE binaries that deliberately export
+# the SAME extern "C" symbol names (see ../Shared/PluginApi.h) --
+# that's exactly what lets HotReloadContext line them up and patch one
+# into the other at runtime. add_lib_module() assumes one canonical
+# build per module name and would not fit two builds of the same name
+# needing to coexist, so this is plain add_library(), reusing the
+# project's usual output-directory/warnings helpers directly. Gated on
