support make check

as a smoke test. I got the following error when following the readme instructions:

Start with the README instructions and reproduce the shown ./compgpt.bin command, then inspect how the project defines or invokes the requested make check smoke test. Trace the failing executable lookup and confirm the finished check runs successfully using the documented setup.
