Currently, we use
LOAD_WITH_ALTERED_SEARCH_PATHto load DLL libraries on Windows. With this pull request, if loading with the above fails, we useLOAD_LIBRARY_SEARCH_USER_DIRS.This is a minimalist version of the idea proposed on Discourse. Rather than replacing
LOAD_WITH_ALTERED_SEARCH_PATHwithLOAD_LIBRARY_SEARCH_DEFAULT_DIRS, we only useLOAD_LIBRARY_SEARCH_USER_DIRSif loading with ``LOAD_WITH_ALTERED_SEARCH_PATH` fails.This allows the user to manually build a search list of directories via
