Fix cmake install target on windows (#315)

* Fix cmake install target on windows

Install the dll to the bin directory, instead of a non-existent CMAKE_INSTALL_RUNTIMEDIR.

* Combine install targets

The only difference was the `RUNTIME DESTINATION` for windows. Since
that is set to the default path, they can use the same definition.
