CGAL users discussion list

Dear Zohar,

Unlike most Windows installers (including CGAL 3.3.1), CGAL 3.4 Windows installer only 
downloads CGAL sources and precompiled third-party libraries.
After running the installer, you should:
- configure CGAL (ie run CMake in CGAL root folder)
- compile CGAL libraries

Then, in order to compile your own application, you have to:
- create a file CMakeLists.txt in your application's folder
- run CMake in your application's folder
- compile your application

This process is detailed in the installation guide
http://www.cgal.org/Manual/3.4/doc_html/installation_manual/contents.html

As the parameterization package requires third-party libraries (TAUCS, LAPACK and BLAS), I 
recommend you to create your CMakeLists.txt from 
CGAL-3.4\examples\Surface_mesh_parameterization\CMakeLists.txt.
