cd <build dir>cmake <path to repo clone>make
buildingextractor <osm extract file> <bin count> <min building size> <output dir>
bin count tell the program to split the input data in multiple bins. It is useful to be able to handle big data sets.
All building whose area is below min building size will be rejected. The unit is roughly square metres. (It is an approximation though.)
