Dependencies

Wuwe separates C++ build dependencies from runtime sidecars and external services. This matters because the release contains a static SDK: consuming applications must still make the enabled public link dependencies available to CMake.

Official release profiles

Capability	Windows x64	Linux x64	macOS 14+ arm64
Default HTTP backend	cpr/libcurl	cpr/libcurl	cpr/libcurl
TLS	Schannel	OpenSSL	OpenSSL
SQLite	Required	Required	Required
Document parsing	Tika and bundled Temurin 21	Tika and bundled Temurin 21	Tika and bundled Temurin 21

The configure step uses vcpkg.json and its pinned builtin-baseline to restore missing manifest dependencies into the selected build tree. It does not install them globally.

Inventory

Dependency	Used for	Delivery
CMake and a C++20 compiler	Building Wuwe and consumers	Build environment
cpr/libcurl	Default HTTP transport	Fetched at the revision pinned in src/CMakeLists.txt for official builds; source consumers may provide an existing cpr::cpr target
cpp-httplib	Alternate HTTP client and MCP HTTP listener	Checked-in header
OpenSSL	Linux/macOS TLS and the optional Windows OpenSSL profile	vcpkg or another compatible development package
Python 3	Controlled Python execution and the macOS restricted-process backend	Host installation; configure python_interpreter explicitly when it is not on PATH
SQLite3	Durable memory and knowledge storage	vcpkg in official profiles; compatible package for SDK consumers
nlohmann/json	JSON representation and codecs	Checked-in headers
Apache Tika Server	PDF and Office parsing	Default bundled sidecar; may be omitted or externally managed
Temurin 21 JRE	Runs the bundled Tika server	Default platform bundle; may be omitted when Java is supplied by the host
Qdrant	Optional vector service	Deployed separately and accessed over HTTP

TLS selection

Set WUWE_TLS_BACKEND at configure time:

Value	Behavior
native	Uses the platform/libcurl-native backend; Windows selects Schannel
openssl	Requires OpenSSL and links it explicitly
auto	Uses OpenSSL when found, otherwise the native backend

The official presets use deterministic choices: native on Windows and openssl on Linux/macOS. The Windows OpenSSL variant is available as windows-vcpkg-openssl.

cmake --preset windows-vcpkg-openssl
cmake --build --preset windows-vcpkg-openssl-release

WUWE_ENABLE_HTTPLIB_SSL controls HTTPS in the cpp-httplib backend. It is effective only when the selected build has OpenSSL.

SQLite selection

Set WUWE_SQLITE_MODE at configure time:

Value	Behavior
on	Requires SQLite; configuration fails when it is unavailable
auto	Enables SQLite when found
off	Builds without SQLite-backed capabilities

The official presets use on. A SQLite-enabled installed package calls find_dependency for the provider selected during the Wuwe build.

SQLite provides durable local storage, not a vector database. sqlite_knowledge_index stores embeddings as JSON and computes similarity with a linear scan in C++. Use Qdrant or an application-specific remote index for large semantic collections or service-scale concurrency.

Installed-package behavior

find_package(wuwe 1 CONFIG REQUIRED)
target_link_libraries(my_app PRIVATE wuwe::wuwe)

The exported configuration exposes the resolved HTTP, TLS, OpenSSL, cpp-httplib HTTPS, and SQLite capabilities. Missing required link dependencies fail during find_package(wuwe) instead of appearing later as unresolved targets.

The bundled curl build disables Brotli and zstd to keep the static link interface reproducible. gzip and deflate remain available through curl's zlib support.

Dependency-specific CPR and curl options are scoped to the dependency fetch. Wuwe no longer forces global BUILD_SHARED_LIBS, TLS, or compression cache values in a parent CMake project.
