Usage: ./build.sh [options]

Possible options:
  -h,         --help                  Display help
  -p,         --pybind                Compile python bindings
  -n,         --no-tests              Don't build tests
  -u,         --no-unpack             Don't unpack datasets
  -j[N],      --jobs[=N]              Allow N jobs at once (default [=1])
  -d,         --debug                 Set debug build type
  -s[S],      --sanitizer[=S]         Build with sanitizer S (has effect only for debug build).
                                      Possible values of S: ADDRESS, UB.
                                      ADDRESS - Address Sanitizer
                                      UB      - Undefined Behavior Sanitizer
  -l                                  Use Link Time Optimization
  -g                                  Use GDB's debug information format
