Support for Qt 5 [FeatureRequest]

[yossioo]

Compiling with catkin build on Kubuntu 18.04+Melodic:
Found unsuitable Qt version "5.9.5" from /usr/bin/qmake, this code requires Qt 4.x

Any plans to adapt to Qt 5?

We are already supporting Qt 5. See the CMakeLists.txt.

I also just checked this and succeeded compiling the plugin with the following setup:

• Ubuntu 18.04.2
• ROS melodic
• Qt 5.9.5

Please check your Qt installation and check that rviz_QT_VERSION inside of CMakeLists.txt is really equal to 5.9.5.

Well, for some reason I had some really old version of this package:<version>0.0.2</version>
Cloning fresh resolved the problem.
