Kisak-Strike is a project by a developer using the leaked CSGO source code to create an open-source version of the game. The post recounts the initial leak, the difficulty of building CSGO, and the transition to a new build system using CMake. The developer includes examples of the benefits of using CMake, such as code completion and finding classes that derive from specific interfaces. The project aims to preserve and maintain the game at its 2017-era stage, but many parts are still not functional, and the developer must use debug versions of the game to analyze the missing features.
