It seems that the necessary 3rd party library qscintilla is not correctly linked to your project. All missing references belong to methods from the qscintilla library. Please make sure, that you have the qscintilla package installed. If you use qt5, the command looks like this:
sudo apt-get install libqt5scintilla2-dev
which will also install the main libqt5scintilla2 package. Then, make sure that the QSCINTILLA_LIBRARY entry in CMake is correctly set to the qscintilla2.so file (or similar filename,
use the latest version that you can locate in your lib directory) and re-generate the itom project before calling make again.
As you can see, it is also necessary to install the -dev package of qscintilla and not only the main package.
I hope that this hint might help. Else I have to check my linux CMake settings, which I cannot do before monday next week.
