Changes: - 'r' key now correctly enables RTSP source (was enabling MP4) - 'm' key now correctly enables MP4 source (was enabling RTSP) - Updated method documentation to be clearer about relay() behavior - Simplified comments removing confusing "inverted logic" notes The relay() method controls whether a source feeds data to the decoder.

Solution: + +```cmake +if(DEFINED VCPKG_INSTALLED_DIR) + # TIFF + set(TIFF_INCLUDE_DIR "${VCPKG_INSTALLED_DIR}/include" CACHE PATH "...") + set(TIFF_LIBRARY "${VCPKG_INSTALLED_DIR}/lib/tiff.lib" CACHE FILEPATH "...") + + # ZLIB + set(ZLIB_INCLUDE_DIR "${VCPKG_INSTALLED_DIR}/include" CACHE PATH "...") + set(ZLIB_LIBRARY "${VCPKG_INSTALLED_DIR}/lib/zlib.lib" CACHE FILEPATH "...") + + # PNG, JPEG, LibArchive, WebP (similar pattern) + ... + + # Common paths + set(CMAKE_INCLUDE_PATH "${VCPKG_INSTALLED_DIR}/include" CACHE PATH "...") + set(CMAKE_LIBRARY_PATH "${VCPKG_INSTALLED_DIR}/lib" CACHE PATH "...") +endif() +``` + +### Build Results + +**CMake Configuration**: ✅ SUCCESS +``` +-- Found OpenCV: D:/dws/ApraPipes/_build/vcpkg_installed/x64-windows (found version "4.8.0") +-- Found Protobuf: ...

In standalone sample builds: +- Main build: `CMAKE_BINARY_DIR = _build/` → packages in `_build/vcpkg_installed/` ✓ +- Samples build: `CMAKE_BINARY_DIR = samples/_build/` → vcpkg looks in `samples/_build/vcpkg_installed/` ✗ + +The samples build needed to explicitly point to the main build's vcpkg installation. + +**Secondary Issue**: OpenCV's dependencies use FindModule.cmake (FindTIFF, FindZLIB, etc.) instead of Config files. These modules search standard system locations, not vcpkg directories, requiring explicit hints. + +### Key Learnings + +1. **vcpkg manifest mode complications**: Standalone projects can't easily share a manifest mode installation without explicit configuration. + +2. **Find modules vs Config files**: Modern CMake prefers Config files (`find_package(Foo CONFIG)`), but many legacy dependencies still use Find modules that need path hints. + +3. **Dependency cascades**: OpenCV → Protobuf → TIFF → HDF5 → ZLIB → LibArchive...
