Dear all

THX. at least we're getting closer to the problem.

Simply put I don't have libCGAL_Qt5

I did install Qt5 for the MAC
I have done:

sudo port install cgal +qt5 +universal +demos

cmake -gui .

yields

libCGAL_ImageIO is configured
-- Sources for CGAL component library 'CGAL_Qt3' detected
-- Sources for CGAL component library 'CGAL_Qt5' detected
Configuring libCGAL_Qt5
-- libCGAL_Qt5 is missing the dependencies: Qt5Svg Qt5 cannot be
configured.
-- Sources for CGAL component libraries
'CGAL_Core;CGAL_ImageIO;CGAL_Qt3;CGAL_Qt5' detected

So it can sense the CGAL_Qt5.

I think the problem is listed in the CHANGES file:

To
compile libCGAL_Qt5 and demos, you must set the cmake or environment
variable Qt5_DIR to point to the path to the directory containing the
file
Qt5Config.cmake created by your Qt5 installation. If you are using the
open
source edition it should be /path-to/qt-everywhere-opensource-src-
<version>/qtbase/lib/cmake/Qt5.


So apparently libCGAL_Qt5 has to be compiled i.e. built and this was not
clearly
specified in the doc.

Moreover, I don't how to do it. Oh I can find Qt5Config.cmake and it is
correctly
listed in CMakeCache.txt. I just have no idea how to build libCGAL_Qt5

best wishes

Tony
