The fist compilation was done by "qmake; make". This lead to problems which were described earlier.

I removed the source, and just issued a ./build command and now the project was compiled. The application loads, but it seems I still need some dependencies to build some libraries.

It's a shame there is no documentation about the building process, and not the requirements for building (a build.txt file in the root of the project should be enough).

The application seems HUGE, and kinda funky, it will take me a few days until I know how to use it, since now a simple "plot" command does not work (I am missing a library).
