Summary

Add missing required ecosystem dependencies to vcpkg.json and fix empty feature dependency arrays.

5W1H Specification

• Who: monitoring_system maintainers
• What: Add common_system/thread_system dependencies, fix feature definitions
• Where: vcpkg.json
• When: Q1 2025, Tier 3 priority
• Why:
  • Required ecosystem dependencies missing from manifest
  • Feature dependencies are empty arrays (invalid)
  • vcpkg build will fail without declared dependencies
• How:
  1. Add kcenon-common-system as required dependency
  2. Add kcenon-thread-system as required dependency
  3. Fix feature dependency declarations
  4. Update vcpkg.json to standard format

Current Issues

Missing Ecosystem Dependencies

README.md states:

Required Dependencies:

• common_system: IMetricCollector, Result
• thread_system: Async metric collection

Current vcpkg.json:

{
  "dependencies": [
    "gtest"
  ],
  "features": {
    "thread-system": {
      "description": "Enable thread_system integration",
      "dependencies": []
    },
    "logger-system": {
      "description": "Enable logger_system integration",
      "dependencies": []
    }
  }
}

Tasks

• Add kcenon-common-system to dependencies (required)
• Add kcenon-thread-system to dependencies (required)
• Fix feature dependencies (add actual deps or remove features)
• Update vcpkg.json to standard format
• Verify vcpkg manifest mode build succeeds

Acceptance Criteria

• vcpkg.json includes all required ecosystem dependencies
• No empty dependency arrays in features
• vcpkg.json follows ecosystem standard template
• vcpkg install --manifest-mode succeeds
