Building wheel suitable for extensions

Me and @berendkleinhaneveld were investigating if we could build extensions against this package. It seems to be a runtime-only package, which is great, but we need the development files, such as headers and the wrapPython executable.

It looks like overriding the option -DVTK_INSTALL_NO_DEVELOPMENT:BOOL=ON to OFF should do the trick. So we tried that, and more development files ended up in the wheel. However, we are not seeing any header files!

We've been investigating all day, but it's unclear to us what is causing this. Do you guys have any suggestions for where we should be looking?

まず、リポジトリのセットアップスクリプトと VTK_INSTALL_NO_DEVELOPMENT オプションを追跡し、wheel の内容がどのように選択されるかを確認します。生成された wheel に開発用ヘッダーと wrapPython 実行可能ファイルが含まれているか検証します。これらの拡張機能ビルド用ファイルが存在し、使用可能であれば完了です。
