Error: CMake 3.18 or higher is required on Linux

[YancyHsu]

opencv_dart/linux/CMakeLists.txt

Line 4 in dcb17be

cmake_minimum_required(VERSION 3.18)

my system cmake version is :
linux cmd>> cmake --version
result>> cmake version 3.29.6

but when run this line above, it throws:
CMake 3.18 or higher is required. You are running version 3.16.3

i add this line in this CmakeLists.txt, it shows:
add in CmakeLists.txt>> message(WARNING "----${CMAKE_VERSION}")
result>> ----3.16.3

i cant find what is wrong

[YancyHsu]

add in CmakeLists.txt>> message(WARNING "----${CMAKE_ROOT}")
then I got:

----/snap/flutter/145/usr/share/cmake-3.16

so the flutter itself use 3.16

• Snap uses an old version of CMake canonical/flutter-snap#53

Download and install flutter manually, do not use snap.

It requires a minimum cmake verson of 3.18 because file(ARCHIVE_EXTRACT) is only available since 3.18, https://cmake.org/cmake/help/latest/command/file.html#archive-extract

get it, tks

Never mind, I have published v1.0.10+1 with #107 fixed, you can now use it to setup manually if you still want to use snap-installed flutter, remember to set OPENCV_DART_DISABLE_AUTO_BUILD environment variable.
