cmake version

Hi,

I've got a flutter app setup with Drift. I'm running on linux using the snap install of flutter.

When I build the app I get the following error message:

CMake Error at flutter/ephemeral/.plugin_symlinks/sqlite3_flutter_libs/linux/CMakeLists.txt:1 (cmake_minimum_required):
  CMake 3.14 or higher is required.  You are running version 3.10.2

I made a bit of research and found that using the snap install of flutter I cannot upgrade the cmake version used for the build. That's mentioned in the following ticket: flutter/flutter#100183

I tried to manually decrease the cmake requirement in the cmakefile but that's also failing with error

CMake Error at flutter/ephemeral/.plugin_symlinks/sqlite3_flutter_libs/linux/CMakeLists.txt:9 (include):
  include could not find load file:

    FetchContent


CMake Error at flutter/ephemeral/.plugin_symlinks/sqlite3_flutter_libs/linux/CMakeLists.txt:20 (FetchContent_Declare):
  Unknown CMake command "FetchContent_Declare".


Exception: Unable to generate build files

So I suppose that cmake 3.14 is really required here. I have absolutely no knowledge on how cmake works, but I was wondering if it would be possible to make some changes to lower the minimum requirement of cmake is order to support the default flutter installation on linux?

Thanks

I should have done a bit more research before opening this one..they published an upgraded version of cmake flutter snap: canonical/flutter-snap#53

It is in core 20 so can already be installed with: snap refresh --channel=edge/core20 flutter

Unfortunately, we really need that cmake version. I'm not too familiar with all the depths of cmake either, but I think there's no good way around FetchContent which we need to download the native sqlite3 dependency. If anyone is aware of one, I'm happy to take a look at that and lower our minimum required version.

Nice find with the updated snap and the new base snap though! Hopefully this won't be a problem much longer then :)
