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.

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

Grateful for any advice you can give me.

Kind regards,
Vanessa
