What

Change the CMake install(EXPORT) name destination from lib/cmake/DatabaseSystem to
lib/cmake/database_system so find_package(database_system CONFIG) resolves natively.

Why

The monitoring_system vcpkg overlay ports standardized on snake_case PACKAGE_NAME
to match vcpkg port naming conventions (kcenon-database-system → database_system).

Currently the portfile must work around this with a wrapper config file:

# vcpkg-ports/kcenon-database-system/portfile.cmake (wrapper workaround)
vcpkg_cmake_config_fixup(
    PACKAGE_NAME database_system
    CONFIG_PATH lib/cmake/DatabaseSystem   # <-- PascalCase upstream path
)
file(WRITE ".../database_system-config.cmake"
    "include(\".../DatabaseSystemConfig.cmake\")\n"  # <-- indirection wrapper
)

Once this upstream adopts snake_case natively, the CONFIG_PATH override and
wrapper file in the portfile can be removed.

Where

• CMakeLists.txt — install(EXPORT) and configure_package_config_file() calls
• Tracked from: docs(deps): Document snake_case PACKAGE_NAME convention for ecosystem ports monitoring_system#543

How

Acceptance Criteria

• find_package(database_system CONFIG) works directly from the installed cmake directory
• No wrapper config file needed in the vcpkg portfile
• DatabaseSystem::database target still usable (target namespace unchanged)
• Existing consumers' target_link_libraries(... DatabaseSystem::database) still compile

Implementation

In CMakeLists.txt:

# Before
install(EXPORT DatabaseSystemTargets
    NAMESPACE DatabaseSystem::
    DESTINATION lib/cmake/DatabaseSystem
)
configure_package_config_file(... INSTALL_DESTINATION lib/cmake/DatabaseSystem)

# After
install(EXPORT DatabaseSystemTargets
    NAMESPACE DatabaseSystem::
    DESTINATION lib/cmake/database_system
)
configure_package_config_file(... INSTALL_DESTINATION lib/cmake/database_system)
