README.md

The Computational Geometry Algorithms Library (CGAL) is a C++ library that aims to provide easy access to efficient and reliable algorithms in computational geometry.

CGAL releases

The primary vector of distribution of CGAL are sources tarballs, released twice a year, announced on the web site of CGAL. The sources distributed that way can be built using the CGAL installation manual.

CGAL Git repository layout

The Git repository of CGAL has a different layout from release tarballs. It contains a CMakeLists.txt file that serves as anchor for building, and a set of subfolders, so called packages. Most packages implement a data structure or an algorithm for CGAL (e.g., Convex_hull_2, or Triangulation_3); however some packages serve special needs:

Installation - meta-files and CMake-support
Maintenance - infrastructural support
Core, CGALimageIO, Qt_widget, GraphicsView - component libraries
Scripts - scripts to simplify developer's and user's work
Testsuite - infrastructure for testsuite
Documentation - infrastructure for CGAL's manual
STL_Extension - extensions to the standard template library

Compilation and installation

The compilation and installation of CGAL from a sources tarball are described in the CGAL installation manual and in the file INSTALL.md that is at the root of any sources tarball.

CGAL developers, however, usually compile CGAL directly from a local Git repository. That kind of compilation is called a branch build, and is described in the file INSTALL.md that is at the root of the Git repository.
