Revert prior attempted optimisation. Gridding the land pays in some situations, but not all. Restricting to an upper bound might help, but overall, seems too fuzzy to be worth it. On one side is increased cost of Add/Delete + extra test on collision check, on the other is skipping the list iteration. Perhaps for large lists.

#
#  FIND_LIBRARY_WITH_DEBUG
#  -> enhanced FIND_LIBRARY to allow the search for an
#     optional debug library with a WIN32_DEBUG_POSTFIX similar
#     to CMAKE_DEBUG_POSTFIX when creating a shared lib
#     it has to be the second and third argument
