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.
Getting Started with CGAL
Since version 5.0, CGAL is a header-only library, meaning that
it is no longer needed to build CGAL libraries before it can be used.
Head over to the CGAL manual
for usage guides and tutorials that will get you started smoothly.

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 configuring and building programs,
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-supportMaintenance- infrastructural supportCore,CGALimageIO,Qt_widget,GraphicsView- component librariesScripts- scripts to simplify developer's and user's workTestsuite- infrastructure for testsuiteDocumentation- infrastructure for CGAL's manualSTL_Extension- extensions to the standard template library
