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