Qt 5 for ROS melodic

I'm wondering about the proper way to get Qt 5 for ROS melodic on Ubuntu 18.04. I searched for hours but couldn't find any recent tutorials. Last year, I developed this package where I used catkin_create_qt_pkg with qt_create and depending on qt_build and libqt4-dev. Since these packages are not available for ROS melodic, I can not compile the package anymore.

I've found and installed the following package: qt_gui, but without any hint what it does. I assume the qt_gui_cpp package installs Qt 5 and creates the bindings. Can someone give me an overview of what is needed and what these packages do? Is there a recent example for the package.xml and CMakeLists out there? I assume the source code is the same.

I installed the ROS Qt Creator Plug-in 4.9.2, but I assume this does just install a "ROS-ready" IDE without any Qt libraries, right?

I'm also wondering about the differences between ros-melodic-qt-gui, ros-melodic-libqt and ros-melodic-qt.

Needed to make some changes to make the old Qt4 ROS Kinetic GUI compile with Qt5 ROS Melodic. These were:

Renaming the QtGui include to QtWidget
package.xml according to: https://github.com/facontidavide/Plot...
CMakeLists according to: https://gist.github.com/facontidavide...

It's now using only "non-ROS" Qt libraries.

I made a package template here: https://github.com/jstiefel/qt5_ros_m...

Thank you very much! Using the CMake.txt file from your Github repo help us a lot!

I believe I faced the same issue and solved it here. Maybe try changing the macros to Qt5?

The packages seem to be available. There is ros-melodic-qt-gui and there is ros-melodic-libqt. I just don't see how they are used...
