When writing C++ projects with Qt, many people’s first reaction is to directly use Qt Creator to create a <span>.pro</span> project, compile, and run, which goes smoothly. However, once the project needs to interface with an existing CMake build system or needs to be built in a cross-platform CI environment, the <span>.pro</span> file becomes inflexible, … Read more
Introduction: Have you encountered these “dependency hell” issues? Have you ever found yourself debugging a complex CMake project, staring at a screen full of <span>add_subdirectory</span> and <span>target_link_libraries</span>, feeling like you’re solving a maze? Have you wanted to showcase the dependency structure in project documentation, but could only rely on drawing tools to sketch it out … Read more

Introduction: In this article, we will learn how to implement unit testing using the CMake build system with the Google Test framework. Compared to the previous configuration with Catch2, the Google Test framework is not just a header file; it is a library that includes two files that need to be built and linked. We … Read more
Recently, while developing ARM applications, I used Qt version 6.2 to cross-compile the source code. The compilation went smoothly and quickly. However, when I was about to compile the program I had written using the Qt library, I found that it could not be compiled with QMake due to a missing connection in Qml. After … Read more
The traditional development of AutoCAD plugins (.arx) often gets mired in the “project configuration hell” of Visual Studio: from complex SDK integration to version dependencies and manual debugging, a small change can lead to the collapse of the entire project. In the face of today’s strong demand for automation, testability, and portability, this model is … Read more
Using macros as feature switches during compilation is a common practice in C++. Below is a simple example (this example is not simple enough; in fact, it could be done with just one source file. However, for the sake of demonstration, two files are used here).The content of the first source file name.cpp is as … Read more
