Network Isolation and CMake FetchContent

Rudolf J Streif

I have a vendor project which uses CMake FetchContent.

It's simple to override FETCHCONTENT_FULLY_DISCONNECTED=ON which is set in the cmake class. However, that does not fix the issue since network isolation prevents the CMake from downloading the content.

I have not found a way to override the network isolation. Is there one?

Now this is not a discussion about whether FetchContent or not is a good idea and any potential other issues that could arise from using it. For me it's to quickly enable a functionality without jumping through hoops of patching the vendor sources etc.
