Hi,

I am currently trying to build ros from sources on Fedora 29. I run throught the previous issue already commented on Answers.

My new issue is that the package image_view does not find the include repository of the gtk package:

==> Processing catkin package: 'image_view'
==> Building with env: '/PATH/ros_catkin_ws/install_isolated/env.sh'
Makefile exists, skipping explicit cmake invocation...
==> make cmake_check_build_system in '/PATH/ros_catkin_ws/build_isolated/image_view'
==> make -j4 -l4 in '/PATH/ros_catkin_ws/build_isolated/image_view'

I did install the gtk2, gtk3 and gtk+ package using dnf:

$ ls /usr/include/gtk*
/usr/include/gtk-1.2:
gdk  gtk

/usr/include/gtk-2.0:
gdk  gtk

/usr/include/gtk-3.0:
gdk  gtk  unix-print

/usr/include/gtk-unix-print-2.0:
gtk

I guess cmake does not find the repository, or is missing a FindGTK.cmake? How could I help him find it?
