+option(OPENSIM_DISABLE_STATIC_TYPE_REGISTRATION
+"Disable OpenSim from registering bundled `Object` types at static
+initialization time.
+
+By default, the static initializer for each OpenSim library will
+call `RegisterTypes_osimCommon`. This has the handy side-effect of
+making all available `Object` types available at (post-static-init)
+runtime, so that (e.g.) downstream code can immediately load XML
+files. However, it has the drawback that downstream code cannot
+control when, or in which order, registration happens, which can
+(e.g.) prevent setting up application-level logging before registering
+things.
+
+If this is set to `ON` (i.e. disable static type registration) then
+downstream code *must* manually register the OpenSim types it plans
+on using by calling `RegisterTypes_osimLIBRARY` (e.g. `RegisterTypes_osimActuators`),
+or by manually registering each type (e.g. `Object::registerType(PhysicalOffsetFrame());`)." OFF)
