Improved the loading of the external software library: try to load only the dll which is available under the lib/windows-xxx directory, based on the CPU capabilities. E.g.: if the CPU supports AVX2 but only the SSE41 library is available, load it. As soon as the AVX2 library is present, prefer the AVX2 library.
