Rebuild when you switch to a new build and compile in parallel:
./cmk.sh -bj5

Rebuild python
./cmk.sh -p
 
For only make:
./cmk.sh

For make clean;make:
./cmk.sh -c

For using hdf5 without default dir /opt/hdf5v1.10.0:
./cmk.sh -h

For using hdf5 without custom dir /blabla:
./cmk.sh -h -d /blabla

For rebuilding cmake without hdf5 (Use this if you had previously run with hdf5 and now you dont want it)
./cmk.sh -b

For using multiple cores to compile faster:
(all these options work)
./cmk.sh -j9
./cmk.sh -cj9 #with clean
./cmk.sh -hj9 #with hdf5
./cmk.sh -j9 -h #with hdf

For rebuilding only certain sections
./cmk.sh -tg #only text client and gui
./cmk.sh -r #only receiver
