Re: [Buildroot] [PATCH 2/2] package/qt6/qt6declarative: fix select of host-qt6base network

[Thomas Perale via buildroot <buildroot@buildroot.org>]

In reply of:
> The BR2_PACKAGE_QT6DECLARATIVE_QUICK option has some logic to select
> network support in host-qt6base if network support is enabled in
> qt6base. However, it turns out that this is actually required at the
