# other build types are assumed to be incremental and the following items
# are removed to ensure stale build objects don't interfere with each other:
#   - build/bin/**: if libraries are removed from cmake they are not deleted
#                   from bin and can cause random failures
#   - build/ExternalData/**: data files will change over time and removing
#                            the links helps keep it fresh
