Pull Request Overview

This PR adds an end-to-end test to ensure <string> is correctly detected as a missing system include and then resolved when its directory is supplied, fixing issue #13928.

• Introduced test_preprocess_system_include in other_test.py
• Imported glob to locate the system <string> header
• Verified cppcheck emits a missing‐include warning without -I and suppresses it when the include path is provided

Comments suppressed due to low confidence (3)

test/cli/other_test.py:3333

• [nitpick] Hard-coding /usr/include/c++/*/string may not work on all platforms or compiler installations. Consider detecting system include paths via sysconfig or a test fixture, or skip more robustly on unsupported environments.

    g = glob.glob('/usr/include/c++/*/string')

test/cli/other_test.py:3333

• [nitpick] The variable name g is ambiguous. Rename it to something more descriptive like matches or header_paths.

    g = glob.glob('/usr/include/c++/*/string')

test/cli/other_test.py:3345

• [nitpick] The name g0 is not descriptive. Consider renaming it to header_path or string_header for clarity.

    g0 = str(g[0])
