rviz_QT_VERSION Error for a rviz plugin on ROS1
Hello. I'm going to try the Rviz tutorial. I got the source codes from here.
I checked out to the kinetic-devel branch ' for ROS1 Kinetic.
And, I just build with catkin_make.
Then, I got below error.
-- catkin 0.7.14

CMake Error at visualization_tutorials/librviz_tutorial/CMakeLists.txt:25 (find_package):
Could not find a configuration file for package "Qt5" that exactly matches
requested version "5.5.1".
The following configuration files were considered but not accepted:
/usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.6.1
-- Configuring incomplete, errors occurred!
How to fix this issue? Do I should to install Qt5?
Thanks.

The EXACT argument is there to avoid incompatibilities between the version of Qt5 being linked by the tutorial package and the packages that it depends on (ie: RViz). If you don't use the same version, there is a risk of running into ABI incompatibilities, which are hard to diagnose.
Hello, I solved this problem by myself.
I remove the EXACT option on CMakeList.txt placed on each packages.
like
Before
...
find_package(Qt5 ${rviz_QT_VERSION} EXACT REQUIRED Core Widgets)
...
After
...
find_package(Qt5 ${rviz_QT_VERSION} REQUIRED Core Widgets)
...
The point of those is that you need to do every package which have same error.
