What

Add snake_case find_package() wrapper config files for 4 systems whose upstream CMake installs use PascalCase package names. Without these wrappers, consumers calling find_package(container_system CONFIG) cannot find the package — only find_package(ContainerSystem CONFIG) works.

• Current: Portfiles use PascalCase PACKAGE_NAME (LoggerSystem, ContainerSystem, DatabaseSystem, NetworkSystem) without snake_case wrappers
• Expected: Both find_package(container_system) and find_package(ContainerSystem) resolve correctly
• Scope: vcpkg-ports/ overlay portfiles + kcenon/vcpkg-registry portfiles

Affected Systems

Why

• Consumer integration test (integration_tests/vcpkg_consumer/CMakeLists.txt) uses snake_case find_package() calls (lines 29, 40, 60, 74)
• These 4 calls silently fail because no snake_case config files exist
• CI passes because these packages are marked optional — creating a false positive
• Any external consumer following the documented find_package() convention will hit the same failure

Where

Overlay ports (this repo):

• vcpkg-ports/kcenon-logger-system/portfile.cmake
• vcpkg-ports/kcenon-container-system/portfile.cmake
• vcpkg-ports/kcenon-database-system/portfile.cmake
• vcpkg-ports/kcenon-network-system/portfile.cmake

Registry (kcenon/vcpkg-registry):

• ports/kcenon-logger-system/portfile.cmake
• ports/kcenon-container-system/portfile.cmake
• ports/kcenon-database-system/portfile.cmake
• ports/kcenon-network-system/portfile.cmake

How

Technical Approach

Append wrapper file creation to each portfile after vcpkg_cmake_config_fixup():

# Create snake_case wrapper for find_package(container_system CONFIG)
file(WRITE "${CURRENT_PACKAGES_DIR}/share/${PORT}/container_system-config.cmake"
    "include(\"\${CMAKE_CURRENT_LIST_DIR}/ContainerSystemConfig.cmake\")\n"
)
if(EXISTS "${CURRENT_PACKAGES_DIR}/share/${PORT}/ContainerSystemConfigVersion.cmake")
    file(WRITE "${CURRENT_PACKAGES_DIR}/share/${PORT}/container_system-config-version.cmake"
        "include(\"\${CMAKE_CURRENT_LIST_DIR}/ContainerSystemConfigVersion.cmake\")\n"
    )
endif()

Acceptance Criteria

• find_package(logger_system CONFIG) works after vcpkg install
• find_package(container_system CONFIG) works after vcpkg install
• find_package(database_system CONFIG) works after vcpkg install
• find_package(network_system CONFIG) works after vcpkg install
• PascalCase find_package() still works (backward compatible)
• Wrappers added to both overlay ports and vcpkg-registry ports
• validate-vcpkg-chain CI passes with all 8 ports found
