Windows has no RPATH to help executables locate their shared
libraries.  The simplest solution is to put the .exe and .dll
files in the same directory (which can be different from the .lib
import libraries corresponding to the .dll files).

Add code like this at the top of your project:

```
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/bin)
```

This will make all executables go to that one directory, which
may require some other adaptation in your code for other platforms
too.  However, once done this will also put .dll files on Windows
in that directory.
