# On Windows, if eigenpy.dll is not in the same directory than
# the .pyd, it will not be loaded.
# We first try to load eigenpy, then, if it fail and we are on Windows:
#  1. We add all paths inside eigenpy_WINDOWS_DLL_PATH to DllDirectory
#  2. If EIGENPY_WINDOWS_DLL_PATH we add the relative path from the
#     package directory to the bin directory to DllDirectory
# This solution is inspired from:
