Just to inform.

I have made a step by step Installation guideline for CGAL and Polyhedron Demo.

Please see the link

https://sites.google.com/site/singhsukhraj/Home/tutorials

And download the pdf provided named: CGAL_Installation_Guide_V2.1.pdf 

You can compare your steps from this guide.

Did you check that QGlviewer has been compiled using Qt5 and not Qt4 ?
You can run ldd on libqglviewer.so for example.

Thanks for that quick reply!

I set the Qt5_DIR environment variable, and also QGLVIEWERROOT=/usr/local/libQGLViewer-2.7.0
This allowed cmake to run and make also compiled with no complaints.

But then trying to run the demo I get

./periodic_3_triangulation_3_demo

dyld: Library not loaded: QGLViewer.framework/Versions/2/QGLViewer
  Referenced from: /Users/vanessa/Software/cgal-releases-CGAL-4.10/Periodic_3_triangulation_3/demo/Periodic_3_triangulation_3/./periodic_3_triangulation_3_demo
  Reason: image not found
Trace/BPT trap: 5

Any hints on this one?

Regards,
Vanessa

Did you set the environment variable Qt5_DIR to point to the path to
the directory containing the file Qt5Config.cmake from your Qt5 installation?

I've downloaded and installed CGAL-4.10 on Mac OS 10.10.5

I build and compiled with Qt5 and got the following libraries
~/cgal-releases-CGAL-4.10/build/lib/ :

libCGAL.13.0.0.dylib            libCGAL_Core.13.0.0.dylib       libCGAL_ImageIO.13.0.0.dylib
libCGAL_Qt5.13.0.0.dylib
libCGAL.13.dylib                libCGAL_Core.13.dylib           libCGAL_ImageIO.13.dylib
libCGAL_Qt5.13.dylib
libCGAL.dylib                   libCGAL_Core.dylib              libCGAL_ImageIO.dylib           libCGAL_Qt5.dylib

I set the CGAL_DIR=~/cgal-releases-CGAL-4.10/build

I then tried to compile demos for Periodic_3_triangulation_3:
In the directory
~/cgal-releases-CGAL-4.10/Periodic_3_triangulation_3/demo/Periodic_3_triangulation_3
I ran

cmake .

and get the following

-- libCGAL_Qt5 is missing the dependencies: Qt5OpenGL Qt5Svg Qt5 cannot be
configured.
-- NOTICE: The CGAL_Qt5 library was not configured.

I don't understand why cmake can't find the CGAL_Qt5 library.

Grateful for any advice you can give me.

Kind regards,
Vanessa
