Unable to run on linux

[lil5]

A clear and concise problem description:
I have tried to add objectbox to my project, but just having objectbox in my dependencies is already enough to trigger an error.

This error is that CMake version is not up to date enough (requires 3.11 or higher) and perceives an installed version of 3.10.2. This is strange as my installed version is 3.16.3 which fits the requirement.

The project I am running this on is a flutter project where the flutter run command uses linux-x64 as device a.k.a. (desktop).

Flutter is installed using snap.

Speculation
I fear that snap provides a different version of CMake.

Basic info (please complete the following information):

• ObjectBox version: 1.2.0
• Flutter/Dart SDK: 2.5.0
• Null-safety enabled: yes
• Reproducibility: always
• OS: Linux mint 20.2 x86_64, Kernel: 5.4.0-86-generic
• Device/Emulator: linux-x64

Steps to reproduce

1. Install Linux mint or Ubuntu 20.10 derivative
2. Install flutter using snap
3. Create a project
4. Add ObjectBox as per examples of ObjectBox-flutter to dependencies

Expected behavior

Project still works

Code

dependencies:
  flutter:
    sdk: flutter
  objectbox: ^1.2.0
  objectbox_flutter_libs: ^1.2.0

dev_dependencies:
  build_runner: ^1.0.0
  objectbox_generator: any
  flutter_test:
    sdk: flutter

This is indeed a snap issue.

Please follow on to canonical/flutter-snap#53

My advise like others have said in other related issues is, don't use snap.
