CMake ExternalProject

Hi,

How you download Polyscope with its main dependencies using CMake ExternalProject command:

https://cmake.org/cmake/help/latest/module/ExternalProject.html

This is a command that downloads github repository. But it must be setup so that dependencies are included and built. Do you have any example using it?

I use this command to download Eigen, Boost, CGAL and would like to add Polyscope in the same workflow, but it is out of my learning knowledge since it is not a header only library. This is one example how I use this command in my CMake projects: https://github.com/petrasvestartas/CMAKE/blob/main/super_build/example_eigen/CMakeLists.txt

Commencez par la documentation CMake ExternalProject liée et par le CMakeLists.txt d’exemple du dépôt référencé. Déterminez comment Polyscope, Eigen, Boost et CGAL doivent être téléchargés et compilés ensemble. Le travail est terminé lorsqu’un exemple ExternalProject documenté et fonctionnel pour ce flux de dépendances est disponible.
