update dependencies

[bc0n]

The dependencies should be more explicit that you need to be building OpenModelica from source; make hangs on:

./OMSensPlugin.h:7:10: fatal error: ../OMEdit/OMEditLIB/Interfaces/InformationInterface.h: No such file or directory
 #include "../OMEdit/OMEditLIB/Interfaces/InformationInterface.h"

This header isn't in OpenModelica/OMEdit's source...and building it failed on not having antlr installed. Though I see that project is archived now and might not provide the correct header. I also needed to install qttools5-dev-tools.

Equivalently, is there a docker image building all of the dependencies?
