| FindProtobuf |
| ------------ |
| |
| Locate and configure the Google Protocol Buffers library. |
| |
| The following variables can be set and are optional: |
| |
| ``Protobuf_SRC_ROOT_FOLDER`` |
| When compiling with MSVC, if this cache variable is set |
| the protobuf-default VS project build locations |
| (vsprojects/Debug and vsprojects/Release |
| or vsprojects/x64/Debug and vsprojects/x64/Release) |
| will be searched for libraries and binaries. |
| ``Protobuf_IMPORT_DIRS`` |
| List of additional directories to be searched for |
| imported .proto files. |
| ``Protobuf_DEBUG`` |
| Show debug messages. |
| ``Protobuf_USE_STATIC_LIBS`` |
| Set to ON to force the use of the static libraries. |
| Default is OFF. |
| |
| Defines the following variables: |
| |
| ``Protobuf_FOUND`` |
| Found the Google Protocol Buffers library |
| (libprotobuf & header files) |
| ``Protobuf_VERSION`` |
| Version of package found. |
| ``Protobuf_INCLUDE_DIRS`` |
| Include directories for Google Protocol Buffers |
| ``Protobuf_LIBRARIES`` |
| The protobuf libraries |
| ``Protobuf_PROTOC_LIBRARIES`` |
| The protoc libraries |
| ``Protobuf_LITE_LIBRARIES`` |
| The protobuf-lite libraries |
| |
| The following :prop_tgt:`IMPORTED` targets are also defined: |
| |
| ``protobuf::libprotobuf`` |
| The protobuf library. |
| ``protobuf::libprotobuf-lite`` |
| The protobuf lite library. |
| ``protobuf::libprotoc`` |
| The protoc library. |
| ``protobuf::protoc`` |
| The protoc compiler. |
| |
| The following cache variables are also available to set or use: |
| |
| ``Protobuf_LIBRARY`` |
| The protobuf library |
| ``Protobuf_PROTOC_LIBRARY`` |
| The protoc library |
| ``Protobuf_INCLUDE_DIR`` |
| The include directory for protocol buffers |
| ``Protobuf_PROTOC_EXECUTABLE`` |
| The protoc compiler |
| ``Protobuf_LIBRARY_DEBUG`` |
| The protobuf library (debug) |
| ``Protobuf_PROTOC_LIBRARY_DEBUG`` |
| The protoc library (debug) |
| ``Protobuf_LITE_LIBRARY`` |
| The protobuf lite library |
| ``Protobuf_LITE_LIBRARY_DEBUG`` |
| The protobuf lite library (debug) |
| |
| Example: |
| |
| .. code-block:: cmake |
| |
| find_package(Protobuf REQUIRED) |
| include_directories(${Protobuf_INCLUDE_DIRS}) |
| include_directories(${CMAKE_CURRENT_BINARY_DIR}) |
| protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS foo.proto) |
| protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS EXPORT_MACRO DLL_EXPORT foo.proto) |
| protobuf_generate_cpp(PROTO_SRCS PROTO_HDRS DESCRIPTORS PROTO_DESCS foo.proto) |
| protobuf_generate_python(PROTO_PY foo.proto) |
| add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS}) |
| target_link_libraries(bar ${Protobuf_LIBRARIES}) |
| |
| .. note:: |
| The ``protobuf_generate_cpp`` and ``protobuf_generate_python`` |
| functions and :command:`add_executable` or :command:`add_library` |
| calls only work properly within the same directory. |
| |
| .. command:: protobuf_generate_cpp |
| |
| Add custom commands to process ``.proto`` files to C++:: |
| |
| protobuf_generate_cpp (<SRCS> <HDRS> |
| [DESCRIPTORS <DESC>] [EXPORT_MACRO <MACRO>] [<ARGN>...]) |
| |
| ``SRCS`` |
| Variable to define with autogenerated source files |
| ``HDRS`` |
| Variable to define with autogenerated header files |
| ``DESCRIPTORS`` |
| Variable to define with autogenerated descriptor files, if requested. |
| ``EXPORT_MACRO`` |
| is a macro which should expand to ``__declspec(dllexport)`` or |
| ``__declspec(dllimport)`` depending on what is being compiled. |
| ``ARGN`` |
| ``.proto`` files |
| |
| .. command:: protobuf_generate_python |
| |
| Add custom commands to process ``.proto`` files to Python:: |
| |
| protobuf_generate_python (<PY> [<ARGN>...]) |
| |
| ``PY`` |
| Variable to define with autogenerated Python files |
| ``ARGN`` |
| ``.proto`` filess |
