So, if all you want to do with this is to hold a shared pointer, then this can
be done in a simpler way. You can have the class take a
`std::shared_ptr<mutex>` and call this using the shared_ptr [aliasing
constructor](https://en.cppreference.com/w/cpp/memory/shared_ptr/shared_ptr)
from the shared pointer of your choice (e.g.
`TargetAPILock(std::shared_ptr<mutex>(target_sp, target_sp->m_mutex))`)
