    Make CGAL3.9 work on Mac OS X 10.7.2 to run only CGAL examples(Demos will not run with this procedure)

    • Download src code from the website
      • Extract it in your home directory
      • Open Terminal and go to the folder CGAL3.9
      • run cmake-gui . (don’t forget the dot after a space in this command)
      • Configure : upper window will look red
      • un-mark CGAL-QT3 and CGAL-QT4 in the camke-gui upper window
      • Configure again
      • make
      • make install
      • Done!

    To run demos:

    • Install QT4 then open Cmake-gui in CGAL src code (of CGAL src code)
      • Mark CGAL_QT4 in the cmake-gui upper window
      • Configure again
      • make
      • make install
      • Done!
