install wwWidgets failed

[SimbadSubZero]

hi all,
I have downloaded the last wwWidgest wwWidgets-0.9.6.tar.gz and tried to follow the installation guide from wwWidgets website but with no success.
Could you please write the specific instructions which I need to do from terminal.
qmake and make commands and maybe more.

Thanks a lot
Simbad

The make command is failed with
/usr/bin/ld: cannot find -lwwwidgets4
