/*! \page installation GUDHI installation
 *  \tableofcontents
 * As GUDHI is a header only library, there is no need to install the library.
 * 
 * Examples of GUDHI headers inclusion can be found in \ref utilities.
 * 
 * \section compiling Compiling
 * The library uses c++17 and requires <a target="_blank" href="https://www.boost.org/">Boost</a>  &ge; 1.66.0
 * and <a target="_blank" href="https://cmake.org/">CMake</a> &ge; 3.8.
 * It is a multi-platform library and compiles on Linux, Mac OSX and Visual Studio 2017.
 * 
 * \subsection utilities Utilities and examples
 * To build the utilities, run the following commands in a terminal:
\verbatim  cd /path-to-gudhi/
mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=Release ..
make \endverbatim
 * By default, examples are disabled. You can activate their compilation with
 * <a href="https://cmake.org/cmake/help/latest/manual/ccmake.1.html">ccmake</a> (on Linux and Mac OSX),
 * <a href="https://cmake.org/cmake/help/latest/manual/cmake-gui.1.html">cmake-gui</a> (on Windows) or by modifying the
 * cmake command as follows :
\verbatim  cmake -DCMAKE_BUILD_TYPE=Release -DWITH_GUDHI_EXAMPLE=ON ..
make \endverbatim
 * A list of utilities and examples is available <a href="examples.html">here</a>.
 * 
 * \subsection libraryinstallation Installation
 * To install the library (headers and activated utilities), run the following command in a terminal:
 * \verbatim  make install \endverbatim
 * This action may require to be in the sudoer or administrator of the machine in function of the operating system and
 * of <a href="https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html">CMAKE_INSTALL_PREFIX</a>.
 *
 * \note Python module will be compiled by the `make` command, but `make install` will not install it. Please refer to
 * the <a href="https://gudhi.inria.fr/python/latest/installation.html#gudhi-python-module-installation">Python
 * module installation documentation</a>.
 * 
 * \subsection testsuites Test suites
 * To test your build, run the following command in a terminal:
 * \verbatim make test \endverbatim
 * `make test` is using <a href="https://cmake.org/cmake/help/latest/manual/ctest.1.html">Ctest</a> (CMake test driver
 * program). If some of the tests are failing, please send us the result of the following command:
 * \verbatim ctest --output-on-failure \endverbatim
 * Testing fetching datasets feature requires the use of the internet and is disabled by default. If you want to include this test, set WITH_GUDHI_REMOTE_TEST to ON when building in the previous step (note that this test is included in the python module):
 * \verbatim cmake -DCMAKE_BUILD_TYPE=Release -DWITH_GUDHI_TEST=ON -DWITH_GUDHI_REMOTE_TEST=ON --DWITH_GUDHI_PYTHON=ON .. \endverbatim
 * 
 * \subsection documentationgeneration C++ documentation
 * To generate the C++ documentation, the <a target="_blank" href="http://www.doxygen.org/">doxygen</a> program
 * is required (version &ge; 1.9.5 is advised). Run the following command in a terminal:
 * \verbatim make doxygen \endverbatim
 * Documentation will be generated in a folder named <code>html</code>.
 *
 * In case there is not a full setup present and only the documentation should be build the following command sequence
 * can be used:
\verbatim  cmake -DWITH_GUDHI_THIRD_PARTY=OFF ..
make doxygen\endverbatim
 *
 * \subsection helloworld Hello world !
 * The <a target="_blank" href="https://github.com/GUDHI/hello-gudhi-world">Hello world for GUDHI</a>
 * project is an example to help developers to make their own C++ project on top of the GUDHI library.
 *
 * \section optionallibrary Optional third-party library
 * \subsection gmp GMP
 * The multi-field persistent homology algorithm requires GMP which is a free library for arbitrary-precision
 * arithmetic, operating on signed integers, rational numbers, and floating point numbers.
 * 
 * The following example requires the <a target="_blank" href="https://gmplib.org/">GNU Multiple Precision Arithmetic
 * Library</a> (GMP) and will not be built if GMP is not installed:
 * \li \gudhi_example_link{Persistent_cohomology,rips_multifield_persistence.cpp}
 *
 * Having GMP version 4.2 or higher installed is recommended.
 * 
 * \subsection cgal CGAL
 * Some GUDHI modules (cf. \ref main_page "modules list"), and few examples require CGAL, a C++ library that provides
 * easy access to efficient and reliable geometric algorithms.
 *
 * \note There is no need to install CGAL, you can just <CODE>cmake -DCMAKE_BUILD_TYPE=Release . && make</CODE> CGAL
 * (or even <CODE>cmake -DCMAKE_BUILD_TYPE=Release -DCGAL_HEADER_ONLY=ON .</CODE>), thereafter you will be able to
 * compile GUDHI by calling <CODE>cmake -DCMAKE_BUILD_TYPE=Release -DCGAL_DIR=/your/path/to/CGAL-X.Y .. && make</CODE>
 * 
 * The procedure to install this library according to
 * your operating system is detailed here http://doc.cgal.org/latest/Manual/installation.html
 * 
 * The following examples/utilities require the <a target="_blank" href="http://www.cgal.org/">Computational Geometry Algorithms
 * Library</a> (CGAL \cite cgal:eb-19b) and will not be built if CGAL version 4.11.0 or higher is not installed:
