Worked on build system improvements for the intel/pti-gpu repository, focusing on refining include-path handling to reduce compiler warnings and simplify environment setup. The approach involved consolidating include-path management across C and C++ code, replacing the use of CPATH with explicit C_INCLUDE_PATH and CPLUS_INCLUDE_PATH variables to enhance build determinism and cross-language compatibility. Leveraging skills in build system configuration and environment variable management, the changes streamlined developer onboarding, improved CI reliability, and reduced build noise. All modifications were implemented using Shell scripting, resulting in a more robust and maintainable build process while maintaining compatibility across different development environments.
