During January 2026, Levizh focused on build system hardening for the levizh/rt-thread repository, addressing a persistent issue in CMakeLists.txt generation. By enhancing the handling of CPPDEFINES and macro definitions, Levizh resolved TypeErrors that arose from varied macro formats, including those generated by SCons. The core fix was implemented in Python within cmake.py, ensuring robust support for different macro definition types during CMake target generation. This targeted patch improved build reliability and reduced CI flakiness across projects. Levizh’s work demonstrated depth in build system management, CMake, and Python scripting, with added documentation to guide manual verification of the solution.
