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

リンク先の CMake ExternalProject ドキュメントと、参照先リポジトリにあるサンプルの CMakeLists.txt から始めてください。Polyscope、Eigen、Boost、CGAL をどのようにまとめてダウンロードし、ビルドすべきかを判断してください。この依存関係のワークフローに対する、文書化され動作する ExternalProject の例が完成すれば完了です。
