I was trying to get the LBPH classifier for Java for OpenCV and to do that I need to use cmake. For this case thy are saying that the minimum version for the cmake is: "3.29" and I had 3.22.
I upgraded as it is suggested here: how I upgreaded
I am trying to use this command with cmake:"cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=/home/alex/opencv_contrib" as it is presented in here: cmake
But I still have this error:
CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.CMake Warning (dev) in CMakeLists.txt: No project() command is present. The top-level CMakeLists.txt file must contain a literal, direct call to the project() command. Add a line of code such as project(ProjectName) near the top of the file, but after cmake_minimum_required(). CMake is pretending there is a "project(Project)" command on the first line.This warning is for project developers. Use -Wno-dev to suppress it.CMake Warning (dev) in CMakeLists.txt: cmake_minimum_required() should be called prior to this top-level project() call. Please see the cmake-commands(7) manual for usage documentation of both commands.This warning is for project developers. Use -Wno-dev to suppress it.CMake Error at CMakeLists.txt:2 (ocv_define_module): Unknown CMake command "ocv_define_module".CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as cmake_minimum_required(VERSION 3.29) should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project. For more information run "cmake --help-policy CMP0000".This warning is for project developers. Use -Wno-dev to suppress it.and I have used the "cmake --version" command and this is the result:
cmake version 3.29.3CMake suite maintained and supported by Kitware (kitware.com/cmake).
