Thanks Maxime,

Will I need to uninstall libcgal-dev before doing so? Is this like an extension to libcgal-dev or is this libcgal-dev + qt5 component?

I think you should install libcgal-qt5-dev then.

Hi,

I just followed the CGAL's getting started guide: sudo apt-get install libcgal-dev

I have compiled and run CGAL program in the past but for some reason I decided to not use Qt5 or create_single_source_cgal_program. I used add_executable and it has always worked fine. But now I would like to ultilise CGAL's integrated graphic library to speed up my work.

Thanks & Regards

I installed CGAL through apt-get so everything is in the default folder
(/usr/lib/x86_64-linux-gnu/cmake/CGAL). My main concern here is the command
"create_single_source_cgal_program" is not recognised, but you can also see
that I also having trouble getting Qt5 to work probably (NOTICE: The
CGAL_Qt5 library was not configured. CGAL was configured with
WITH_CGAL_Qt5=ON, but one of the dependencies of CGAL_Qt5 was not configured
properly).

I have not modified the CMakeLists.txt file.

Help a learner out? Thank you.
