FindProtobuf

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})

protobuf_generate_cpp
