Creating a CMake Script for a Program Using CGAL

To compile a program that is not shipped with CGAL, it is recommended to also rely on a CMake-supported configuration using a `CMakeLists.txt`.

The Bourne-shell script `cgal_create_CMakeLists.txt` can be used to create such `CMakeLists.txt` files. This script resides in the `scripts` directory of CGAL (e.g. `CGAL-5.6.3``/scripts` directory if you have downloaded a tarball). Executing `cgal_create_CMakeLists.txt` in an application directory creates a `CMakeLists.txt` containing rules to build the contained application(s). Three command line options determine details of the configuration.

`-s source`

  If this parameter is given the script will create a single executable for 'source' linked with compilations of all other source files (`*.cc`, `*.cp`, `*.cxx`, `*.cpp`, `*.CPP`, `*.c++`, or `*.C`). This behaviour is usually needed for (graphical) demos.

  If the parameter is not given, the script creates one executable for each given source file.

`-c com1:com2:...`

  Lists components ("com1", "com2") of CGAL to which the executable(s) should be linked. Valid components are CGAL's libraries (i.e. "Core", "ImageIO", and "Qt5"). An example is `-c Core`.

`-b boost1:boost2:...`

  Lists components ("boost1", "boost2") of Boost to which the executable(s) should be linked. Valid options are, for instance, "filesystem" or "program_options".

These options should suffice to create a `CMakeLists.txt` script for most directories containing programs. However, in some special cases, it might still be required to create the script manually, for instance, if some source files/executables need a different linking than other source files. The Section How to use CGAL with CMake provides more details.
