The debug version has the -DSPARSE_DEBUG enabled. It is intended to include more verification in the debug version. For now the debug version remain the same as the release version. Because the debug version has different compile flags, all *.o file need to be recompile under the debug flag. These debug version object file is stored in debug/ directory. <name>-dbg is the finial debug version of the program <name>. Full compile time is doubled because every thing needs to compile twice. One for release version. One for debug version.
