CGAL users discussion list

[Martin Baeker <>]

Dear all,

I have a program library based on CGAL3.3. It consists of several
C++-Classes, each with its own .hpp and .cpp-file. 

I am at a loss on how to achieve the same thing with newer versions of
CGAL that use cmake. The cgal_create_cmake_script is not sufficient because
I need to link to the library from my classes together when building
an executable. OTOH, I need correct compilation with all CGAL-stuff as
well.

Here is a very simple example (not meaningfulin itself) of what I want to do:

File Pointclass.H

#include <CGAL/Gmpq.h>
#include <CGAL/Cartesian.h>

typedef CGAL::Cartesian<CGAL::Gmpq>   Kernel;
typedef Kernel::Point_3    Point;

class Mypoint: public Point
{
public:
  int index;
  Mypoint(int in);
};

File Pointclass.C

#include "Pointclass.H"

Mypoint::Mypoint(int in)
{
  index = in;
}

File main.C

#include "Pointclass.H"

int main()
{
  Mypoint p(1);
  std::cout << p.index << std::endl;
  return 0;
  
}


So how do I set up cmake so that main can be linked to Pointclass and
that the dependence of the two is known?

I suppose there is a simple way how to do this, but I'm not able to
find it...

Thanks for any help,

Martin.
