CGAL installation + CGAL and QT5

Question

I just installed CGAL from ubuntu 16.04 package manger and tried to run an example according to this: http://www.cgal.org/FAQ.html#debian_demos

after runing, the following message appeared: NOTICE: This demo requires CGAL and Qt5, and will not be compiled.

But the following packages are already installed:

Package , Installed version

libcgal-demo , 4.7-4

libcgal-dev , 4.7-4

libcgal-ipelets , 4.7-4

libcgal-qt5-11 , 4.7-4

libcgal-qt5-dev , 4.7-4

libcgal-11v5 , 4.7-4

cmake , 3.5.1-1ubuntu1

cmake-data , 3.5.1-1ubuntu1

g++ , 4:5.3.1-1ubuntu1

I'm wondering what is the problem?

Answer 1

Try installing the following packages: qtscript5-dev, libqt5opengl5-dev, libqt5svg5-dev or alternatively try to find demo that is not compiling and change the line in CMakeLists.txt containing

find_package(Qt5 QUIET COMPONENTS Xml Script OpenGL Svg)

into:

find_package(Qt5 COMPONENTS Xml Script OpenGL Svg)

This will allow you to track the necessary packages (you are probably missing different packages than me).
