Using QtCreator as your IDE
Download the binary for your system from https://www.qt.io/download-open-source/#section-9
Download the deal.II indentation style from qtcreator-dealii-format and set it under Tools->Options->C++->Code style->Import.
If you use a cmake build that is installed in your local user acccount, it needs to be set under settings->build&run->cmake.
In your default kit (settings->build&run->kits) select Qt version "none". Otherwise some reserved words like "signal" are not parsed correctly by qtcreator.
You can download dealii-prm.xml and put it into ~/.config/QtProject/qtcreator/generic-highlighter to get syntax highlighting for .prm files.
Open the CMakeLists.txt and then choose the existing build directory.
Note that version 3.6 and newer revamped the cmake support which means that setting up the project takes a few more clicks (uncheck all but one build types/directories).
