In the previous article, “Introduction to CMake Build Tool for ESP32,” we introduced the most basic usage of CMake with a “Hello World” program. Today, we will provide a detailed explanation of the CMakeLists.txt file. CMakeLists.txt The CMakeLists.txt file is the core configuration file for the CMake build tool. It contains a series of instructions … Read more
Most open-source storage systems are built on the Linux operating system. This article introduces storage technology while also covering some Linux content, focusing on practicality. It will be helpful for both application development and kernel understanding. When our project consists of thousands of files, manually writing a Makefile will be a nightmare. Fortunately, CMake helps … Read more
Introduction: Projects usually start with a single CMakeLists.txt file, which grows over time. In this article, we will demonstrate a mechanism to split the CMakeLists.txt into smaller units. The motivation for splitting CMakeLists.txt into modules: The main CMakeLists.txt is easier to read; CMake modules can be reused in other projects Combined with functions, modules can … Read more
Hello, today we will delve into a very practical and challenging topic—Integrating External Libraries in CMake: How to Manage Third-Party Libraries Using find_package and ExternalProject. In most C++ projects, integrating external libraries is an indispensable part. Efficiently and elegantly managing these dependencies, especially during multi-platform builds, is a skill every developer needs to master. 1. … Read more
1. Introduction to CMake CMake is a cross-platform installation (compilation) tool that can describe the installation (compilation process) for all platforms using simple statements. It can output various makefiles or project files, and can test the C++ features supported by the compiler, similar to automake under UNIX. The configuration file for CMake is named CMakeLists.txt. … Read more
1. CMake Variable Reference and Definition (1) Use ${} to reference variables. In statements like IF, use the variable name directly without ${}. (2) Custom variables can be defined implicitly and explicitly. For example, the PROJECT command implicitly defines <projectname>_BINARY_DIR and <projectname>_SOURCE_DIR. Explicitly defining variables can be done using the SET command. For example: SET(HELLO_SRC … Read more
