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.
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 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:
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_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 add_executable() or add_library()
calls only work properly within the same directory.
-
protobuf_generate_cpp¶ Add custom commands to process
.protofiles to C++:protobuf_generate_cpp (<SRCS> <HDRS> [<ARGN>...])
SRCS- Variable to define with autogenerated source files
HDRS- Variable to define with autogenerated header files
ARGN.protofiles
-
protobuf_generate_python¶ Add custom commands to process
.protofiles to Python:protobuf_generate_python (<PY> [<ARGN>...])
PY- Variable to define with autogenerated Python files
ARGN.protofiless
