NOTICE

Since Version 5.0, CGAL is a header-only library it is not needed to build and install it. Usage of CGAL should thus simply amount to:

git clone https://github.com/CGAL/cgal.git /path/to/cgal.git
cd /path/to/cgal.git/Triangulation_2/examples/Triangulation_2
mkdir -p build/debug
cd build/debug
cmake -DCMAKE_BUILD_TYPE=Debug -DCGAL_DIR=/path/to/cgal.git
make

in the case of the building of an example in debug mode.

For more information head over to the CGAL manual. Note that this page describes the setting of CGAL as a sources release and, as such, files are organized in a slightly different way, see the Layout of the CGAL Git Repository.

Building a Program Using CGAL

To compile a program using CGAL, simply set CGAL_DIR to the location of the directory containing CGALConfig.cmake (for example the root of the extracted source archive or the root of a git checkout).

Here is an example of how to build in debug the examples from the 3D Triangulations package:

 cd /path/to/cgal.git/Triangulation_3/examples/Triangulation_3
 mkdir -p build/debug
 cd build/debug
 cmake -DCGAL_DIR:PATH=/path/to/cgal.git ../..
 make

If you are trying to build examples or tests that do not already have a CMakeLists.txt, you can trigger its creation by calling the script cgal_create_cmake_script found in /path/to/cgal.git/Scripts/scripts/ at the root of the example/test directory. Here is an example for the examples of the 2D Triangulation package:

 cd /path/to/cgal.git/Triangulation_2/examples/Triangulation_2
 /path/to/cgal.git/Scripts/scripts/cgal_create_cmake_script
 cd /path/to/cgal.git/Triangulation_2/examples/Triangulation_2
 mkdir -p build/debug
 cd build/debug
 cmake -DCGAL_DIR:PATH=/path/to/cgal.git ../..
 make
