OpenCV Version: 4.2.0 OpenCV-Contrib Version: 4.2.0 CMake Version: 3.20.0 When developing image algorithms with OpenCV, being able to display the pixel where the mouse falls on the image can greatly improve development efficiency. I searched this issue and found that most bloggers use callback functions to solve it, which not only adds extra complexity but … Read more
CMakeLists.txt file contains a set of instructions and descriptions that define the source files and targets (executable files, libraries, or both) of a project. When you create a new project, CLion automatically generates a CMakeLists.txt file and places it in the project root directory. To open the project, you can point CLion to the top-level … Read more

The settings required to build a CMake project are consolidated into a CMake configuration file. It includes the toolchain and build type, as well as CMake options such as generators and environment variables. You can configure multiple configuration files for a project to build targets with different compilers or different settings. To set up a … Read more
Link: https://ukabuer.me/blog/more-modern-cmake/ For C/C++ developers, managing projects often becomes quite tricky when it comes to complex third-party dependencies, especially when cross-platform development is required. CMake, as a cross-platform build process management tool, provides mature solutions for finding and introducing third-party dependencies, creating build systems, testing programs, and installation. By writing a CMakeLists.txt file once and … Read more
1 Overview In our daily development and operations work, we encounter various software packages; software packages can be broadly divided into two categories: binary files, such as (exe, rpm, bin, etc.); the other category is source files (various tarballs). This article will introduce the most commonly used RPM software package in Linux systems, discussing the … Read more
